-# TIG Repository Cleanup - JPL Proprietary Files Removed
-
-**Date**: April 23, 2026  
-**Branch**: `opensource-vicar-build`
-
-## Summary
-
-Cleaned up the TIG repository by removing all files that reference JPL internal/proprietary resources, ensuring the repository contains only publicly distributable open-source code.
-
-## Files Removed
-
-### Dockerfiles (3 files)
-1. **`vicar-native-toolkit/docker/Dockerfile.with-rpms`**
-   - Used JPL Artifactory for RPM packages
-   - Required JPL internal CA certificates
-   - Contained hardcoded Artifactory URLs
-
-2. **`vicar-native-toolkit/docker/Dockerfile.tig-demo`**
-   - Depended on `vicar-tools:with-rpms` base image
-   - Indirectly required JPL resources
-
-3. **`vicar-native-toolkit/docker/Dockerfile.local-binaries`**
-   - Used local pre-built binaries (potentially from JPL builds)
-   - No clear provenance of binary source
-
-### Scripts (3 files)
-1. **`vicar-native-toolkit/scripts/build-image-with-rpms.sh`**
-   - Built Docker image using JPL Artifactory RPMs
-   - Required JPL network access and credentials
-
-2. **`vicar-native-toolkit/scripts/build-tig-demo-image.sh`**
-   - Built demo image based on RPM-based build
-   - Indirectly required JPL resources
-
-3. **`vicar-native-toolkit/scripts/build-image-local-binaries.sh`**
-   - Used local binaries without clear source
-
-### Configuration Files (2 files)
-1. **`vicar-native-toolkit/docker/rpm-repo.repo`**
-   - JPL Artifactory repository configuration
-   - Contained internal URLs and authentication setup
-
-2. **`vicar-native-toolkit/docker/rpm-repo.repo.example`**
-   - Example Artifactory configuration
-   - Exposed internal infrastructure details
-
-## What Remains (Open Source Only)
-
-### Dockerfiles
-- ✅ **`Dockerfile.opensource`** - Downloads pre-built binaries from public GitHub releases
-  - Source: https://github.com/NASA-AMMOS/VICAR/releases
-  - No proprietary dependencies
-  - Fully reproducible by anyone
-
-### Scripts
-- ✅ **`build-opensource-image.sh`** - Builds open-source Docker image
-- ✅ **`vicario`** - VICAR to PNG/JPEG/TIFF converter (Python script)
-- ✅ **`setup.sh`**, **`setup-linux.sh`**, **`setup-macos.sh`** - Local dev setup
-- ✅ **`test-wrapper.sh`** - Testing utilities
-
-### Documentation
-- ✅ All documentation files remain (README, guides, etc.)
-- ✅ No proprietary information in docs
-
-## Verification
-
-### No JPL References Remaining
-```bash
-$ cd /Users/han/IdeaProjects/NASA-AMMOS/tig
-$ grep -r "artifactory\|jpl.*internal\|rpm-repo" vicar-native-toolkit/ --include="*.sh" --include="Dockerfile*"
-# (No results - clean!)
-```
-
-### Remaining Files Check
-```bash
-$ ls vicar-native-toolkit/docker/
-Dockerfile.opensource
-
-$ ls vicar-native-toolkit/scripts/
-build-opensource-image.sh  setup-macos.sh  test-wrapper.sh
-setup-linux.sh             setup.sh        vicario
-```
-
-## Impact
-
-### ✅ Benefits
-1. **Public Distribution Ready**: Repository can now be made public without concerns
-2. **Clear Provenance**: All artifacts trace back to public GitHub releases
-3. **Reproducible**: Anyone can build the same images without special access
-4. **Compliance**: No exposure of internal infrastructure or credentials
-5. **Maintenance**: Simpler codebase with single build path
-
-### ⚠️ Considerations
-1. **JPL Internal Use**: Internal JPL users will need to use separate private repo for RPM-based builds
-2. **Migration Path**: Existing internal users should migrate to open-source build
-3. **Documentation**: Internal docs should be updated to reference new build process
-
-## Open Source Build Details
-
-### What's Included
-- **VICAR 5.0 binaries** from GitHub releases
-- **External libraries** (GDAL, HDF5, OpenJPEG, etc.) from GitHub releases
-- **VISOR calibration files** for open-source missions (Phoenix, MER)
-- **VISOR sample data** for testing and demos
-- **Vicario converter** for image format conversion
-
-### Build Process
-```bash
-# Local build
-cd vicar-native-toolkit
-./scripts/build-opensource-image.sh
-
-# GitHub Actions (automatic)
-# Triggers on push to branches, tags, or PRs
-# Publishes to: ghcr.io/nasa-ammos/tig/vicar-native-toolkit
-```
-
-### Image Tags
-- `opensource` - Latest open-source build
-- `pr-N` - Pull request builds
-- `sha-XXXXXX` - Specific commit builds
-- `vX.Y.Z` - Version releases
-
-## Next Steps
-
-1. ✅ **Cleanup complete** - All proprietary files removed
-2. ✅ **Open-source build tested** - Verified locally (~6 min build)
-3. ✅ **GitHub Actions workflow** - Automated CI/CD in place
-4. ⏳ **Verify Actions build** - Ensure GitHub Actions completes successfully
-5. ⏳ **Create PR to master** - Merge changes when ready
-6. ⏳ **Repository visibility** - Consider making repository public
-

-| Aspect | This Implementation | Build from Source | RPM-Based |
-|--------|-------------------|-------------------|-----------|
-| **Build Time** | 5-10 min | 30-60 min | 5-10 min |
-| **Requirements** | Docker only | Docker + Build tools | Docker + JPL access |
-| **Internet Access** | GitHub only | GitHub + Deps | JPL Artifactory |
-| **Reproducibility** | Exact binaries | Varies by toolchain | Exact RPMs |
-| **Distribution** | Freely distributable | Freely distributable | Internal only |
-| **Size** | ~2-3 GB | ~2-3 GB | ~1.5 GB |
-| **Maintenance** | Track releases | Track source changes | Track RPM updates |
-
-## Benefits
-
-1. **Fast Builds**: 5-10 minutes vs 30-60 minutes for source builds
-2. **Reproducible**: Uses specific release versions (5.0)
-3. **Public Distribution**: No proprietary dependencies
-4. **Complete**: Includes calibrations and sample data
-5. **Easy to Use**: Simple commands, wrapper scripts
-6. **CI/CD Ready**: GitHub Actions workflow included

-
-## Potential Issues and Solutions
-
-### Issue 1: Large Image Size
-**Solution**: This is expected for a complete VICAR distribution. Future optimization possible.
-
-### Issue 2: Limited Calibration Data
-**Current**: Only Phoenix and MER calibrations included  
-**Reason**: These are openly available; mission-specific data (M20, MSL) requires JPL access  
-**Solution**: Users can mount additional calibration data as needed
-
-### Issue 3: Platform Specificity
-**Current**: Only linux/amd64 supported  
-**Reason**: VICAR pre-built binaries only available for x86-64 Linux  
-**Future**: Could add macOS support using mac64-osx binaries
-
-### Issue 4: Network Dependency
-**Observation**: Build requires downloading from GitHub  
-**Solution**: GitHub is highly available; builds are cached in CI/CD
-

-
-## Benefits
-
-1. **Public Distribution**: The tig repository can now be shared publicly without concerns about proprietary dependencies.
-
-2. **Reproducible Builds**: Anyone can build the same VICAR environment from source.
-
-3. **CI/CD Integration**: Automated testing and deployment ensure quality.
-
-4. **Version Control**: Multiple tags allow users to pin to specific versions.
-
-5. **Transparency**: Open-source build process increases trust and allows community contributions.
-
-## Considerations
-
-1. **Build Time**: The open-source build using pre-built binaries is fast (5-10 min), comparable to RPM-based builds.
-
-2. **Image Size**: The final image will be ~2-3GB (includes binaries, libraries, calibrations, and sample data).
-
-3. **Maintenance**: Need to keep VICAR version in sync with upstream releases (currently using v5.0).
-
-4. **Testing**: Initial testing is recommended before publicizing the repository.
-
-5. **Calibrations**: Only includes open-source mission calibrations (Phoenix, MER). Mission-specific M20/MSL calibrations are not included.
-
-6. **VISOR Data**: Includes calibration files and sample data for testing and demos.
-
-## Testing Plan
-
-Before making the repository public, verify:
-
-- ✅ Dockerfile builds successfully
-- ⏳ GitHub Actions workflow runs without errors
-- ⏳ Smoke tests pass (basic VICAR commands)
-- ⏳ Integration tests with real data
-- ⏳ X11 forwarding works on Linux and macOS
-- ⏳ Documentation is clear and complete
-
-## Questions to Resolve
-
-1. **Repository Visibility**: Is the TIG repository ready to be made public, or should it remain internal?
-
-2. **Naming**: Is `vicar-native-toolkit` the desired name, or should it be changed?
-
-3. **Licensing**: Does the repository need a LICENSE file?
-
-4. **Demo Data**: Should we include sample VICAR images for testing?
-
-5. **Additional Packages**: Are there Python packages or other tools that should be added to the image?
-

+# Quick Start - Running Demos with Your Data
+
+## Option 1: Original Demo (Temporary Container)
+
+Fast, one-time mesh generation from stereo pairs or XYZ files.
+
+### With Pre-computed XYZ
+
+```bash
+./demo-mesh-generation-with-xyz.sh \
+  --xyz /path/to/pointcloud.xyz \
+  --texture /path/to/texture.img
+```
+
+**Time:** ~90 seconds
+
+### With Stereo Pair
+
+```bash
+./demo-mesh-generation-with-xyz.sh \
+  --stereo-left /path/to/NLM_*_FDR_*.VIC \
+  --stereo-right /path/to/NRM_*_FDR_*.VIC
+```
+
+**Time:** ~10+ minutes (full resolution images)
+
+**Requirements:**
+- Left and right images from **same acquisition** (matching SCLK timestamp)
+- Full-resolution or subframe images (not downsampled/thumbnails)
+- MARS calibration files mounted at `./calibration/` (see setup below)
+
+**Output:** `terrain-intelligence-generator/docker/workspace/terrain.obj`, `texture.png`
+
+**Cleanup:**
+```bash
+docker stop tig-mesh-demo && docker rm tig-mesh-demo
+```
+
+---
+
+## Option 2: Native Toolkit Demo (Persistent Container)
+
+Native-looking commands for interactive development. Container stays running.
+
+### One-time Setup
+
+```bash
+# 1. Install direnv
+sudo apt install direnv  # Ubuntu/Debian
+brew install direnv      # macOS
+
+# 2. Add to shell (choose one)
+echo 'eval "$(direnv hook bash)"' >> ~/.bashrc
+echo 'eval "$(direnv hook zsh)"' >> ~/.zshrc
+
+# 3. Restart shell
+source ~/.bashrc  # or source ~/.zshrc
+
+# 4. Trust the toolkit directory
+cd vicar-native-toolkit
+direnv allow
+cd ..
+```
+
+### With Pre-computed XYZ
+
+```bash
+./demo-mesh-native-toolkit.sh \
+  --xyz /path/to/pointcloud.xyz \
+  --texture /path/to/texture.img
+```
+
+### With Stereo Pair
+
+```bash
+./demo-mesh-native-toolkit.sh \
+  --stereo-left /path/to/NLM_*_FDR_*.VIC \
+  --stereo-right /path/to/NRM_*_FDR_*.VIC
+```
+
+**Output:** `vicar-native-toolkit/workspace/terrain.obj`, `texture.png`
+
+**Container Management:**
+```bash
+cd vicar-native-toolkit
+
+# Check status
+toolkit-status
+
+# Open shell in container
+toolkit-shell
+
+# Stop container
+toolkit-stop
+```
+
+---
+
+## Where to Get Data
+
+### Mars 2020 NavCam Stereo Pairs
+
+**VISOR (Recommended):**
+- https://mars.nasa.gov/mmgis-maps/M20/Layers/json/
+- Look for `*_FDR_*.VIC` files (Full Data Record format)
+- Download matching left (NLM) and right (NRM) pairs
+
+**PDS Geosciences Node:**
+- https://pds-geosciences.wustl.edu/missions/mars2020/
+- Navigate to NCAM data products
+- Download stereo pairs with matching SCLK timestamps
+
+**Example filenames:**
+```
+Left:  NLM_1835_0829848458_777FDR_N0874924NCAM00230_0A02LLJ01.VIC
+Right: NRM_1835_0829848458_777FDR_N0874924NCAM00230_0A02LLJ01.VIC
+        ^^^^^^^^^^^^^^^^^^^^  <-- Must match (SCLK timestamp)
+```
+
+### Pre-computed XYZ Files
+
+VISOR provides pre-computed XYZ point clouds:
+- Search for `*_xyz_*.img` files
+- Much faster than stereo processing
+
+---
+
+## Troubleshooting
+
+### "MARS calibration not found"
+
+```bash
+# Calibration must be mounted at runtime (not included in image)
+# Check calibration location
+ls calibration/camera_models/
+
+# If missing, download from: https://github.com/NASA-AMMOS/VICAR
+# Place in ./calibration/ directory
+```
+
+### "Stereo images don't match"
+
+**Error:** Disparity calculation fails or produces garbage
+
+**Solution:** Verify images are from same acquisition:
+```bash
+# Check SCLK timestamp in filename
+# Must match exactly between left (NLM) and right (NRM)
+```
+
+### "direnv not allowed"
+
+```bash
+cd vicar-native-toolkit
+direnv allow
+```
+
+### "Out of memory"
+
+**Increase Docker memory:**
+- Docker Desktop: Settings → Resources → Memory (recommend 16GB)
+
+**Or use smaller images:**
+- Use subframe/windowed images instead of full resolution
+- Reduce marsmesh `res_max` parameter
+
+### "Container won't start"
+
+```bash
+# Check Docker running
+docker ps
+
+# Remove stale container
+docker stop vicar-sidecar && docker rm vicar-sidecar
+
+# Re-enter toolkit directory
+cd vicar-native-toolkit
+cd .. && cd vicar-native-toolkit
+```
+
+---
+
+## Comparison: Which Demo to Use?
+
+| Feature | Original Demo | Native Toolkit |
+|---------|--------------|----------------|
+| **Setup** | None | direnv one-time setup |
+| **Speed** | Container startup each run (~5s) | Instant (persistent) |
+| **Use case** | One-off processing | Interactive development |
+| **Cleanup** | Manual | Automatic (optional) |
+| **Commands** | `docker exec ...` | Native-looking |
+| **Best for** | Production pipelines | Exploration, testing |
+
+---
+
+## Example Workflows
+
+### Quick Test with Sample Data
+
+```bash
+# Using vicar-native-toolkit workspace data
+./demo-mesh-generation-with-xyz.sh \
+  --xyz vicar-native-toolkit/workspace/pointcloud.xyz \
+  --texture vicar-native-toolkit/workspace/texture.img
+```
+
+### Process Real Mars 2020 Data
+
+```bash
+# 1. Download stereo pair from VISOR
+cd /tmp
+wget https://mars.nasa.gov/.../NLM_1835_0829848458_777FDR_*.VIC
+wget https://mars.nasa.gov/.../NRM_1835_0829848458_777FDR_*.VIC
+
+# 2. Generate mesh
+cd /path/to/tig
+./demo-mesh-generation-with-xyz.sh \
+  --stereo-left /tmp/NLM_*.VIC \
+  --stereo-right /tmp/NRM_*.VIC
+
+# 3. View mesh
+# Import terrain-intelligence-generator/docker/workspace/terrain.obj into Blender/MeshLab
+```
+
+### Interactive Exploration
+
+```bash
+# 1. Setup toolkit (one-time)
+cd vicar-native-toolkit
+direnv allow
+
+# 2. Work interactively
+cd workspace
+gen out=test.img nl=100 ns=100
+label test.img
+marsmesh inp=pointcloud.xyz out=custom.obj
+
+# 3. Container stays running for next session
+```
+
+---
+
+## Viewing Meshes
+
+**Desktop Applications:**
+- **Blender:** File → Import → Wavefront (.obj)
+- **MeshLab:** File → Import Mesh

+### Option 1: Automated Native Toolkit (Recommended)
+
+Get native-like VICAR commands in one step:
+
+```bash
+cd vicar-native-toolkit
+./bootstrap.sh
+# ✓ Pulls Docker image
+# ✓ Starts container  
+# ✓ Creates ~550 command wrappers
+# ✓ Ready in <30 seconds
+
+# Now use VICAR commands directly
+gen out=test.img nl=10 ns=10
+toolkit-status
+```
+
+See [vicar-native-toolkit/README.md](vicar-native-toolkit/README.md) for details.
+
+### Option 2: Run Mesh Generation Demo
+
+```bash
+# Pull the Docker image
+docker pull ghcr.io/nasa-ammos/tig/terrain-intelligence-generator:opensource
+
+# Run NavCam mesh generation demo
+./demo-mesh-generation-with-xyz.sh \
+  --stereo-left /path/to/left.VIC \
+  --stereo-right /path/to/right.VIC
+```
+
+**Output**: Textured 3D mesh in Wavefront OBJ format (~10 minutes)
+
+### View Results

+
+### Camera Models
+- **CAHVORE**: Camera model format (Center, Axis, Horizontal, Vertical, Optical, Radial, Entrance)
+- **Purpose**: Geometric projection, distortion correction
+- **Usage**: Automatic lookup by MARS tools based on image labels
+
+## Docker Architecture
+
+### Image Layers
+
+```
+Base Layer: Ubuntu 20.04
+    ↓
+VICAR Build Layer: Dependencies + VICAR source
+    ↓
+MARS Tools Layer: Compiled MARS programs
+    ↓
+Runtime Layer: Java + vicario.jar + calibration
+    ↓
+Entry Point: Shell with VICAR environment
+```
+
+### Volume Mounts
+
+- `/workspace` - Input/output files
+- `/usr/local/vicar/mars_calib` - M2020 calibration (read-only)
+- `/usr/local/vicar/visor_data` - Sample data (optional)
+
+### Environment Variables
+
+- `V2TOP` - VICAR installation root
+- `MARS_CONFIG_PATH` - Calibration path for MARS tools
+- `TAE` - TAE configuration directory
+
+## Performance Characteristics
+
+### Processing Time (1280x960 images)
+
+| Stage | Tool | Time | Parallelizable |
+|-------|------|------|----------------|
+| Initial correlation | marscorr | ~6 min | CPU cores |
+| Refinement | marscor3 | ~2 min | Yes (-omp_on) |
+| XYZ generation | marsxyz | ~1 min | No |
+| Mesh creation | marsmesh | ~30 sec | No |
+| Texture convert | vicario | <1 sec | No |
+| **Total** | | **~10 min** | |
+
+### Memory Requirements
+
+- **Minimum**: 8GB RAM
+- **Recommended**: 16GB RAM
+- **High-res meshes**: 32GB RAM (5120x3840 inputs)
+
+### Disk Usage
+
+- **Container**: ~15GB
+- **Per mesh output**: ~300MB (1280x960 input)
+- **Temporary files**: ~30MB (disparity maps)
+
+## Security Considerations
+
+- Container runs as root (VICAR requirement)
+- Volume mounts use `:Z` flag for SELinux compatibility
+- Calibration mounted read-only (`:ro`)
+- No network access required

+Three demos are available for generating 3D terrain meshes from Mars 2020 NavCam stereo images:
+
+1. **Full Pipeline** (`demo-mesh-generation-with-xyz.sh`) - Complete stereo correlation → XYZ → mesh
+2. **Quick Demo** (`demo-mesh-generation-complete.sh`) - Fast mesh generation from pre-computed XYZ
+3. **Native Toolkit** (`demo-mesh-native-toolkit.sh`) - Native-looking commands via vicar-native-toolkit
+
+## Demo 1: Full Pipeline with XYZ Calculation
+
+Complete stereo mesh generation pipeline from raw stereo pair.
+
+### What It Does
+
+1. **Stereo Correlation** (marscorr + marscor3) - Generate disparity maps (~8 minutes)
+2. **XYZ Generation** (marsxyz) - Convert disparity to 3D coordinates (~1 minute)
+3. **Mesh Creation** (marsmesh) - Triangulate surface (~30 seconds)
+4. **Texture Conversion** (vicario) - VICAR to PNG (<1 second)
+
+**Total Time:** ~10 minutes for 1280x960 NavCam images
+
+### Prerequisites
+
+- Docker Engine 20.10+
+- M2020 NavCam stereo pair (FDR format)
+- 16GB RAM recommended
+- M2020 calibration files mounted at `./calibration/` (see [Calibration Setup](#calibration-setup))
+
+### Usage
+
+```bash
+# Run with your stereo pair
+./demo-mesh-generation-with-xyz.sh \
+  --stereo-left /path/to/NLM_*_FDR_*.VIC \
+  --stereo-right /path/to/NRM_*_FDR_*.VIC
+```
+
+**Output** (in `workspace/`):
+- `terrain.obj` - 3D mesh (~273M, 1.2M vertices)
+- `terrain.mtl` - Material file
+- `texture.png` - Texture image (1280x960)
+- `pointcloud.xyz` - XYZ point cloud (~15M)
+- `disparity.img` - Disparity map
+- `terrain.iv` - OpenInventor format
+
+### Example
+
+```bash
+# With M2020 NavCam data
+./demo-mesh-generation-with-xyz.sh \
+  --stereo-left NLM_1835_0829848458_777FDR_N0874924NCAM00230_0A02LLJ01.VIC \
+  --stereo-right NRM_1835_0829848458_777FDR_N0874924NCAM00230_0A02LLJ01.VIC
+```
+
+### Algorithm Parameters
+
+**Stereo Correlation:**
+- Initial (marscorr): `template=15 search=51 quality=0.2`
+- Refinement (marscor3): `template=11 search=31 quality=0.4 -omp_on`

+- Gap filling: `maxgap=5`
+
+## Demo 2: Quick Mesh from Pre-computed XYZ
+
+Fast demo using pre-computed XYZ point cloud from VISOR sample data.
+
+### What It Does
+
+1. **Copy XYZ** - Load pre-computed point cloud from VISOR
+2. **Mesh Creation** (marsmesh) - Triangulate surface (~30 seconds)
+3. **Texture Conversion** (vicario) - VICAR to PNG (<1 second)
+
+**Total Time:** ~90 seconds
+
+### Usage
+
+```bash
+# Run with defaults (uses VISOR sample data)
+./demo-mesh-generation-complete.sh
+```
+
+**Output** (in `workspace/`):
+- `terrain.obj` - 3D mesh (~179M, 752K vertices)
+- `terrain.mtl` - Material file
+- `texture.png` - Texture image (1280x960)
+- `pointcloud.xyz` - XYZ point cloud (~13M)
+- `terrain.iv` - OpenInventor format
+
+### Data Source
+
+Uses pre-computed NavCam XYZ from VISOR samples:
+- **XYZ:** `nlf_1835_0829848458_777xyz_n0874924ncam00230_0a02llj08.img`
+- **Texture:** `nlm_1835_0829848458_777fdr_n0874924ncam00230_0a02llj01.vic`
+
+VISOR (Visible Sightseeing Observables Repository) provides processed M2020 data products.
+
+## Demo 3: Native Toolkit with vicar-native-toolkit
+
+**NEW:** Demonstrates native-looking VICAR commands using the vicar-native-toolkit wrapper.
+
+### What It Does
+
+Uses `vicar-native-toolkit` to provide native-looking command execution:
+
+```bash
+# Instead of:
+docker exec vicar-sidecar marsmesh inp=cloud.xyz out=mesh.obj ...
+
+# You run:
+marsmesh inp=cloud.xyz out=mesh.obj ...
+```
+
+Commands look and feel like native binaries but transparently execute inside Docker.
+
+### Key Features
+
+- **Native appearance:** Commands execute from any directory in workspace
+- **Persistent container:** Long-running `vicar-sidecar` container (no startup overhead)
+- **Auto-discovery:** All 200+ VICAR commands automatically wrapped
+- **Path transparency:** Relative paths work naturally
+- **direnv activation:** Toolkit auto-activates when entering directory
+
+### Prerequisites
+
+- Docker Engine 20.10+
+- **direnv** installed and configured
+- M2020 calibration files (optional, required for stereo processing)
+- Shell integration: `eval "$(direnv hook bash)"` in `.bashrc`
+
+### Setup
+
+```bash
+# 1. Install direnv
+sudo apt install direnv  # Ubuntu/Debian
+brew install direnv      # macOS
+
+# 2. Add to shell profile
+echo 'eval "$(direnv hook bash)"' >> ~/.bashrc
+source ~/.bashrc
+
+# 3. Trust the toolkit directory (one-time)
+cd vicar-native-toolkit
+direnv allow
+```
+
+### Usage
+
+```bash
+# With pre-computed XYZ (fast)
+./demo-mesh-native-toolkit.sh \
+  --xyz pointcloud.IMG \
+  --texture image.IMG
+
+# With stereo pair (full pipeline)
+./demo-mesh-native-toolkit.sh \
+  --stereo-left NLM_*.VIC \
+  --stereo-right NRM_*.VIC
+```
+
+### How It Works
+
+1. **Container startup:** `direnv` detects `.envrc` and starts `vicar-sidecar` container
+2. **Wrapper generation:** Auto-discovers VICAR commands and creates wrapper scripts
+3. **PATH injection:** Adds wrappers to `$PATH` transparently
+4. **Command execution:** Wrappers forward to `docker exec` with proper working directory
+
+Example wrapper (`~/.direnv/wrappers/marsmesh`):
+```bash
+#!/bin/bash
+TOOL_NAME="marsmesh"
+CONTAINER_NAME="vicar-sidecar"
+WORKSPACE_ROOT="/path/to/workspace"
+REL_PATH="$(realpath --relative-to="${WORKSPACE_ROOT}" "${PWD}")"
+docker exec -i -w "/workspace/${REL_PATH}" "${CONTAINER_NAME}" "${TOOL_NAME}" "$@"
+```
+
+### Toolkit Commands
+
+Once activated, you have access to:
+
+**Core VICAR:**
+- `gen` - Generate test images
+- `label` - Display VICAR metadata
+- `list` - List image contents
+- `vicario` - VICAR to PNG/JPEG converter
+
+**MARS Terrain Tools:**
+- `marscorr`, `marscor3` - Stereo correlation
+- `marsxyz` - Disparity to XYZ conversion
+- `marsrfilt` - Rover hardware filtering
+- `marsmesh` - Mesh generation
+- `marsmap` - Orthoprojection
+- `marsmos` - Mosaicking
+
+**Utility Commands:**
+- `toolkit-status` - Show container status
+- `toolkit-shell` - Open bash shell in container
+- `toolkit-verify-calib` - Check MARS calibration
+- `toolkit-stop` - Stop and remove container
+- `toolkit-restart` - Restart container
+
+### Output
+
+Same as Demo 1, but generated in `vicar-native-toolkit/workspace/`:
+- `terrain.obj` - 3D mesh
+- `terrain.mtl` - Material file
+- `texture.png` - Texture image
+- `pointcloud.xyz` - XYZ point cloud
+- `pointcloud_filtered.xyz` - Filtered (rover hardware removed)
+
+### Advantages
+
+**vs. Docker Exec Scripts:**
+- ✓ Clean syntax: `marsmesh ...` not `docker exec container bash -c '...'`
+- ✓ Persistent container: No startup/cleanup overhead per command
+- ✓ Natural workflows: Chain commands with pipes/redirection
+- ✓ Interactive use: Better for development/experimentation
+
+**vs. Native Installation:**
+- ✓ Consistent environment: Same VICAR version for all users
+- ✓ Easy updates: `docker pull` to upgrade
+- ✓ No system pollution: VICAR stays containerized
+- ✓ Reproducible: Docker image hash ensures identical behavior
+
+### Container Lifecycle
+
+**Automatic management:**
+- Started on first `cd vicar-native-toolkit` (via direnv)
+- Reused across sessions (persistent)
+- Survives shell exit
+
+**Manual control:**
+```bash
+cd vicar-native-toolkit
+
+# Check status
+toolkit-status
+
+# Open shell in container
+toolkit-shell
+
+# Stop container
+toolkit-stop
+
+# Restart (stop + re-enter directory)
+toolkit-restart
+cd .. && cd -
+```
+
+### Advanced Configuration
+
+Edit `vicar-native-toolkit/.envrc.local`:
+
+```bash
+# Custom calibration path
+export MARS_CONFIG_PATH="/path/to/mars_calib"
+
+# Custom container name
+export CONTAINER_NAME="my-vicar-sidecar"
+
+# Custom image
+export CONTAINER_IMAGE="ghcr.io/nasa-ammos/tig/terrain-intelligence-generator:v2.0"
+
+# Mount parent directory (for accessing files outside workspace)
+export PARENT_DIR="/data"
+export PARENT_MOUNT="/external"
+```
+

+
+## Viewing Meshes
+
+All demos output standard Wavefront OBJ format:
+
+**Desktop viewers:**
+- **Blender:** File → Import → Wavefront (.obj) - Best for editing/rendering
+- **MeshLab:** File → Import Mesh - Best for analysis/measurements
+- **CloudCompare:** File → Open - Best for point cloud comparison
+
+**Online viewers:**
+- https://3dviewer.net/ - No installation required
+- Drag and drop `terrain.obj` + `texture.png`
+
+**Command-line inspection:**
+```bash
+# Vertex count
+grep -c "^v " terrain.obj
+
+# Triangle count
+grep -c "^f " terrain.obj
+
+# Bounding box
+grep "^v " terrain.obj | awk '{print $2,$3,$4}' | \
+  awk 'NR==1{min_x=max_x=$1; min_y=max_y=$2; min_z=max_z=$3}
+       {if($1<min_x) min_x=$1; if($1>max_x) max_x=$1;
+        if($2<min_y) min_y=$2; if($2>max_y) max_y=$2;
+        if($3<min_z) min_z=$3; if($3>max_z) max_z=$3}
+       END{print "X:", min_x, max_x; print "Y:", min_y, max_y; print "Z:", min_z, max_z}'
+```
+
+## Troubleshooting
+
+### Demo 3 (Native Toolkit) Issues
+
+**"direnv not allowed":**
+```bash
+cd vicar-native-toolkit
+direnv allow
+```
+
+**"Commands not found":**
+```bash
+# Check if container running
+docker ps | grep vicar-sidecar
+
+# Check PATH
+echo $PATH | grep -o wrappers
+
+# Re-activate
+cd .. && cd vicar-native-toolkit
+```
+
+**"MARS calibration not found":**
+```bash
+cd vicar-native-toolkit
+toolkit-verify-calib
+```
+
+**Container won't start:**
+```bash
+# Check logs
+docker logs vicar-sidecar
+
+# Force cleanup
+docker stop vicar-sidecar && docker rm vicar-sidecar
+
+# Re-enter directory
+cd .. && cd vicar-native-toolkit
+```
+
+### General Issues
+
+**Out of memory:**
+- Increase Docker memory limit (Settings → Resources)
+- Use smaller images (subframes instead of full resolution)
+- Reduce `res_max` in marsmesh
+
+**Calibration errors:**
+- Verify MARS_CONFIG_PATH points to valid calibration directory
+- Check calibration includes camera models for your instrument
+- Use `find-calibration.sh` to locate calibration files
+
+**Poor mesh quality:**
+- Use full-resolution images (not thumbnails/downsampled)
+- Adjust stereo correlation quality threshold
+- Tune marsmesh decimation parameters
+
+## Data Sources
+
+**M2020 NavCam Images:**
+- VISOR: https://mars.nasa.gov/mmgis-maps/M20/Layers/json/
+- PDS Geosciences Node: https://pds-geosciences.wustl.edu/missions/mars2020/
+- Look for `*_FDR_*.VIC` (Full Data Record format)
+
+**Sample Data:**
+- VISOR pre-computed XYZ products: `*_xyz_*.img`
+- Included in TIG repository: `workspace/samples/`

+# Getting Started with TIG
+
+Quick setup guide for running Mars 2020 stereo mesh generation.
+
+## Prerequisites
+
+- **Docker** or Podman installed
+- **8GB RAM** minimum (16GB recommended)
+- **M2020 stereo images** (NavCam or Mastcam-Z)
+
+## Installation
+
+### Option 1: Use Pre-built Image (Recommended)
+
+```bash
+docker pull ghcr.io/nasa-ammos/tig/terrain-intelligence-generator:opensource
+```
+
+### Option 2: Build Locally
+
+```bash
+cd terrain-intelligence-generator/docker
+docker build -t terrain-intelligence-generator:opensource .
+```
+
+**Note**: Local build requires `vicario.jar` (see [Vicario Reference](../reference/vicario.md))
+
+## Running Your First Demo
+
+### 1. Prepare Data
+
+Get M2020 stereo images from PDS or use sample data:
+
+```bash
+# Sample NavCam stereo pair locations:
+# Left:  NLM_<SCLK>_*FDR_*.VIC
+# Right: NRM_<SCLK>_*FDR_*.VIC
+```
+
+### 2. Run Mesh Generation
+
+```bash
+./demo-mesh-generation-with-xyz.sh \
+  --stereo-left /path/to/left.VIC \
+  --stereo-right /path/to/right.VIC
+```
+
+**Processing time**: ~10 minutes for 1280x960 images
+
+### 3. View Results
+
+```bash
+# Check output
+ls workspace/
+# terrain.obj      - 3D mesh (~273M)
+# terrain.mtl      - Material file
+# texture.png      - Texture (1280x960)
+# pointcloud.xyz   - XYZ data (~15M)
+
+# View mesh
+meshlab workspace/terrain.obj
+# or
+blender workspace/terrain.obj
+```
+
+## What the Demo Does
+
+1. **Stereo Correlation** (marscorr + marscor3)
+   - Matches features between left/right images
+   - Generates disparity map
+   - ~8 minutes
+
+2. **XYZ Generation** (marsxyz)
+   - Converts disparity to 3D coordinates
+   - Filters outliers
+   - ~1 minute
+
+3. **Mesh Creation** (marsmesh)
+   - Triangulates point cloud
+   - Applies texture
+   - ~30 seconds
+
+4. **Format Conversion** (vicario)
+   - Converts VICAR to PNG
+   - <1 second
+
+## Troubleshooting
+
+### Container Name Conflict
+
+```bash
+docker: Error response from daemon: Conflict. The container name "/tig-mesh-demo" is already in use
+```
+
+**Solution**:
+```bash
+docker stop tig-mesh-demo && docker rm tig-mesh-demo
+```
+
+### Out of Memory
+
+```bash
+no additional memory available
+```
+
+**Solution**: Increase Docker memory limit to 16GB or use lower resolution images
+
+### Missing Calibration
+
+```bash
+ERROR: MARS calibration not found
+```
+
+**Solution**: Ensure calibration files are in `terrain-intelligence-generator/docker/mars_calibration_m20/`
+
+## Next Steps
+
+- **[Mesh Generation Demo](demos/mesh-generation.md)** - Detailed walkthrough
+- **[Command Reference](demos/commands.md)** - Available VICAR tools
+- **[Vicario Reference](reference/vicario.md)** - Image format conversion
+
+## Configuration
+
+### Using Custom Calibration
+
+Mount your own M2020 calibration:
+
+```bash
+docker run -v /path/to/calib:/usr/local/vicar/mars_calib:ro ...
+```
+
+### Using Pre-computed XYZ
+
+Skip correlation if you have XYZ files:
+
+```bash
+./demo-mesh-generation-with-xyz.sh \
+  --xyz pointcloud.IMG \
+  --texture image.IMG
+```
+
+See [demos/mesh-generation.md](demos/mesh-generation.md) for details.

+# Building with Java VicarIO
+
+This Docker image uses the Java-based VicarIO library for VICAR image format conversion. The Java version provides better image quality with proper dynamic range rescaling compared to the Python implementation.
+
+## Obtaining vicario.jar
+
+### Build from Source
+
+Once the public VicarIO repository becomes available:
+
+1. Clone the VicarIO repository:
+   ```bash
+   git clone https://github.com/NASA-AMMOS/vicario.git
+   cd vicario
+   ```
+
+2. Build the FAT JAR (includes all dependencies):
+   ```bash
+   mvn -U -Pshade clean install
+   ```
+
+3. Copy the JAR to the Docker build context:
+   ```bash
+   cp target/vicario-*-FAT.jar /path/to/tig/terrain-intelligence-generator/docker/vicario.jar
+   ```
+
+**Note**: The repository is currently being prepared for public release. Check [NASA-AMMOS/vicario](https://github.com/NASA-AMMOS/vicario) for availability.
+
+## Building the Docker Image
+
+Once `vicario.jar` is in place:
+
+```bash
+cd terrain-intelligence-generator/docker
+docker build -t terrain-intelligence-generator:latest .
+```
+
+## Why Java VicarIO?
+
+The Java implementation provides:
+
+- **Correct dynamic range handling**: Automatically rescales 16-bit VICAR images to 8-bit with `oform=byte rescale=true`
+- **Better image quality**: Preserves full dynamic range during conversion
+- **Native VICAR support**: Direct parsing of VICAR labels and binary data
+- **Format flexibility**: Supports PNG, JPEG, TIFF output formats
+
+The wrapper script automatically applies the correct rescaling parameters for standard 2-argument usage:
+```bash
+vicario input.vic output.png
+```
+
+For advanced usage, pass parameters directly:
+```bash
+vicario inp=input.vic out=output.png format=png oform=byte rescale=true
+```

+# Building with Java VicarIO
+
+This Docker image uses the Java-based VicarIO library for VICAR image format conversion. The Java version provides better image quality with proper dynamic range rescaling compared to the Python implementation.
+
+## Obtaining vicario.jar
+
+### Build from Source
+
+Once the public VicarIO repository becomes available:
+
+1. Clone the VicarIO repository:
+   ```bash
+   git clone https://github.com/NASA-AMMOS/vicario.git
+   cd vicario
+   ```
+
+2. Build the FAT JAR (includes all dependencies):
+   ```bash
+   mvn -U -Pshade clean install
+   ```
+
+3. Copy the JAR to the Docker build context:
+   ```bash
+   cp target/vicario-*-FAT.jar /path/to/tig/terrain-intelligence-generator/docker/vicario.jar
+   ```
+
+**Note**: The repository is currently being prepared for public release. Check [NASA-AMMOS/vicario](https://github.com/NASA-AMMOS/vicario) for availability.
+
+## Building the Docker Image
+
+Once `vicario.jar` is in place:
+
+```bash
+cd terrain-intelligence-generator/docker
+docker build -t terrain-intelligence-generator:latest .
+```
+
+## Why Java VicarIO?
+
+The Java implementation provides:
+
+- **Correct dynamic range handling**: Automatically rescales 16-bit VICAR images to 8-bit with `oform=byte rescale=true`
+- **Better image quality**: Preserves full dynamic range during conversion
+- **Native VICAR support**: Direct parsing of VICAR labels and binary data
+- **Format flexibility**: Supports PNG, JPEG, TIFF output formats
+
+The wrapper script automatically applies the correct rescaling parameters for standard 2-argument usage:
+```bash
+vicario input.vic output.png
+```
+
+For advanced usage, pass parameters directly:
+```bash
+vicario inp=input.vic out=output.png format=png oform=byte rescale=true
+```

+# VICAR Native Toolkit Demo - Mars Terrain Mesh Generation
+
+Generate textured 3D terrain meshes from Mars rover stereo images using **native-looking** VICAR commands.
+
+## What This Demo Shows
+
+- **Native-like commands**: Run `marsmesh`, `marsxyz`, `marscorr` as if installed locally
+- **Transparent Docker**: Commands execute in container without Docker syntax
+- **Fast execution**: Long-running container (~50-100ms latency)
+- **Complete pipeline**: Stereo → Disparity → XYZ → 3D Mesh → Texture
+
+## Prerequisites
+
+### Required
+
+- **Docker** - Container runtime
+- **direnv** - Environment automation
+- **~6GB disk space** - For Docker image
+
+### Install direnv
+
+```bash
+# Ubuntu/Debian
+sudo apt install direnv
+
+# macOS
+brew install direnv
+
+# Fedora
+sudo dnf install direnv
+```
+
+### Configure Shell
+
+Add to `~/.bashrc` (bash) or `~/.zshrc` (zsh):
+
+```bash
+# For bash
+eval "$(direnv hook bash)"
+
+# For zsh
+eval "$(direnv hook zsh)"
+```
+
+Then reload:
+
+```bash
+source ~/.bashrc  # or source ~/.zshrc
+```
+
+## Quick Start (3 Steps)
+
+### 1. Activate Toolkit
+
+```bash
+cd vicar-native-toolkit
+direnv allow
+```
+
+**What happens:**
+- ✓ Starts `vicar-sidecar` container
+- ✓ Generates ~550 command wrappers
+- ✓ Adds VICAR commands to PATH
+- ✓ Mounts workspace directory
+
+**Time:** ~30 seconds (first time)
+
+### 2. Verify Activation
+
+```bash
+# Check status
+toolkit-status
+
+# Test basic command
+cd workspace
+gen out=test.img nl=10 ns=10
+```
+
+**Expected output:**
+```
+Beginning VICAR task GEN
+GEN Version 2019-05-28
+GEN task completed
+```
+
+✅ **Success!** No Docker syntax needed.
+
+### 3. Run Mesh Generation
+
+Choose one:
+
+#### Option A: Pre-computed XYZ (Fast ~90 seconds)
+
+```bash
+# From repository root
+./demo-mesh-native-toolkit.sh \
+  --xyz /path/to/pointcloud.xyz \
+  --texture /path/to/image.IMG
+```
+
+#### Option B: Full Stereo Pipeline (Slow ~10-15 minutes)
+
+```bash
+# From repository root
+./demo-mesh-native-toolkit.sh \
+  --stereo-left /path/to/left.VIC \
+  --stereo-right /path/to/right.VIC
+```
+
+**Requirements for stereo processing:**
+- MARS calibration files (automatically detected)
+- Matching stereo pair (same SCLK timestamp)
+
+## Step-by-Step Manual Process
+
+Want to understand each step? Run commands manually:
+
+### Step 0: Activate and Navigate
+
+```bash
+cd vicar-native-toolkit
+direnv allow
+cd workspace
+```
+
+### Step 1: Process Stereo Pair
+
+#### 1a. Copy Stereo Images
+
+```bash
+cp /path/to/left.VIC left.vic
+cp /path/to/right.VIC right.vic
+```
+
+#### 1b. Generate Disparity Map (Initial)
+
+```bash
+marscorr \( left.vic right.vic \) disparity_init.img \
+  template=15 search=51 quality=0.2
+```
+
+**Time:** ~3-5 minutes  
+**Output:** `disparity_init.img`
+
+#### 1c. Refine Disparity Map
+
+```bash
+marscor3 \( left.vic right.vic \) disparity.img \
+  in_disp=disparity_init.img \
+  template=11 search=31 quality=0.4 -omp_on
+```
+
+**Time:** ~5-10 minutes  
+**Output:** `disparity.img`
+
+### Step 2: Generate XYZ Point Cloud
+
+```bash
+marsxyz \( left.vic right.vic \) pointcloud.xyz \
+  disp=disparity.img \
+  error=10.0 abserr=0.15 lined=100 avgline=50 \
+  zlimit=\(-300,300\) spike_range=0.04 outlier=0.5
+```
+
+**Time:** ~30-60 seconds  
+**Output:** `pointcloud.xyz`
+
+### Step 3: Filter Rover Hardware
+
+```bash
+marsrfilt inp=pointcloud.xyz out=pointcloud_filtered.xyz
+```
+
+**Time:** ~5 seconds  
+**Output:** `pointcloud_filtered.xyz` (rover parts removed)
+
+### Step 3: Filter Rover Hardware
+
+```bash
+marsrfilt inp=pointcloud.xyz out=pointcloud_filtered.xyz
+```
+
+**Time:** ~5 seconds  
+**Output:** `pointcloud_filtered.xyz` (rover parts removed)
+- `terrain.lbl` - PDS4 metadata label describing mesh structure
+
+### Step 4: Generate 3D Mesh
+
+```bash
+marsmesh inp=pointcloud_filtered.xyz out=terrain.obj \
+  in_skin=right.vic \
+  x_subsample=1 y_subsample=1 \
+  range_min=0.2 range_mid=100 range_max=100 \
+  lod_levels=10 max_angle=87.5 \
+  res_min=3000 res_max=500000 density=1 -adaptive \
+  maxgap=5
+```
+
+**Time:** ~30 seconds  
+**Output:** `terrain.obj`, `terrain.mtl`, `terrain.iv`, `terrain.lbl`
+
+**Note:** marsmesh generates multiple output files:
+- `terrain.obj` - 3D mesh in Wavefront OBJ format (~55MB)
+- `terrain.mtl` - Material file referencing right.png (auto-converted from right.vic)
+- `terrain.iv` - Open Inventor format mesh (~47MB)
+- `terrain.lbl` - PDS4 metadata label describing mesh structure
+
+### Step 5: Convert Texture to PNG
+
+```bash
+vicario right.vic right.png
+```
+
+**Time:** ~2 seconds  
+**Output:** `right.png` (matches the MTL texture reference)
+
+**Note:** marsmesh automatically converts `.vic` to `.png` in the MTL file, so we create `right.png` to match
+
+### Step 6: View Results
+
+```bash
+ls -lh terrain.obj terrain.mtl texture.png pointcloud_filtered.xyz
+```
+
+## Understanding the Commands
+
+### Native-Looking vs Docker Reality
+
+**What you type:**
+```bash
+marsmesh inp=pointcloud.xyz out=terrain.obj
+```
+
+**What actually happens:**
+```bash
+docker exec -i vicar-sidecar \
+  -w /workspace \
+  marsmesh inp=pointcloud.xyz out=terrain.obj
+```
+
+The wrapper handles all Docker complexity transparently!
+
+### Command Wrappers
+
+All commands are symlinks to a universal wrapper:
+
+```bash
+# Check wrapper
+which marsmesh
+# → .direnv/wrappers/marsmesh
+
+# View wrapper implementation
+cat .direnv/wrappers/marsmesh
+# → Symlink to vicar-exec
+```
+
+### Available Commands
+
+```bash
+# List all 550+ wrappers
+ls .direnv/wrappers/ | wc -l
+
+# Mars processing tools
+ls .direnv/wrappers/ | grep ^mars
+# marscorr, marscor3, marsxyz, marsmesh, marsrfilt, marsmap, marsmos, ...
+
+# Basic VICAR tools
+ls .direnv/wrappers/ | grep -E "^(gen|label|hist|copy)"
+# gen, label, hist, copy, ...
+
+# Format conversion
+ls .direnv/wrappers/ | grep vicario
+# vicario (Java-based image converter)
+```

+## Toolkit Management
+
+### Status and Diagnostics
+
+```bash
+# Show container status
+toolkit-status
+
+# Check running container
+docker ps | grep vicar-sidecar
+
+# View container logs
+docker logs vicar-sidecar
+
+# Verify MARS calibration
+toolkit-verify-calib
+```
+
+### Interactive Shell
+
+```bash
+# Open bash inside container
+toolkit-shell
+
+# Now inside container:
+pwd  # → /workspace
+ls   # See workspace files
+exit
+```
+
+### Container Control
+
+```bash
+# Restart container (after config changes)
+toolkit-restart
+
+# Stop container
+toolkit-stop
+
+# Re-activate (restarts if stopped)
+cd .. && cd -
+direnv allow
+```
+
+### Deactivation
+
+```bash
+# Leave directory - commands disappear from PATH
+cd ..
+
+# Container keeps running in background
+docker ps | grep vicar-sidecar  # Still running
+
+# Re-enter - commands immediately available
+cd vicar-native-toolkit
+which marsmesh  # Works again!
+```
+
+## Configuration
+
+### MARS Calibration
+
+Edit `.envrc.local`:
+
+```bash
+# Container settings
+CONTAINER_NAME="vicar-sidecar"
+CONTAINER_IMAGE="ghcr.io/nasa-ammos/tig/terrain-intelligence-generator:opensource"
+
+# MARS calibration (required for stereo processing)
+MARS_CONFIG_PATH="/path/to/mars_calibration_m20"
+```
+
+Then reload:
+
+```bash
+direnv allow
+toolkit-restart
+toolkit-verify-calib
+```
+
+### Custom Container Image
+
+```bash
+# Edit .envrc.local
+CONTAINER_IMAGE="myregistry/vicar:custom"
+
+# Restart
+toolkit-restart
+```
+
+## Troubleshooting
+
+### "direnv: error .envrc is blocked"
+
+```bash
+cd vicar-native-toolkit
+direnv allow
+```
+
+### "VICAR commands not found"
+
+```bash
+# Check if container is running
+docker ps | grep vicar-sidecar
+
+# Restart toolkit
+toolkit-restart
+
+# Re-enter directory
+cd .. && cd -
+```
+
+### "Container not running"
+
+```bash
+# Check Docker is running
+docker ps
+
+# Remove old container
+docker rm -f vicar-sidecar
+
+# Re-activate
+cd .. && cd vicar-native-toolkit
+direnv allow
+```
+
+### "marscorr: command not found"
+
+```bash
+# Check wrappers generated
+ls .direnv/wrappers/ | wc -l
+
+# If < 500, regenerate:
+toolkit-restart
+```
+
+### "Can't open display" (macOS)
+
+```bash
+# Start XQuartz
+open -a XQuartz
+
+# Allow connections
+xhost +localhost
+
+# Restart container
+toolkit-restart
+```
+
+### Commands run but produce no output
+
+```bash
+# Check current directory
+pwd
+# Must be in workspace/ or subdirectory
+
+# Or use absolute paths
+cd vicar-native-toolkit/workspace
+marsmesh inp=../data/pointcloud.xyz out=terrain.obj
+```
+
+## Performance Tips
+
+### macOS Apple Silicon Optimization
+
+**For M1/M2/M3 Macs:** Enable Rosetta 2 for dramatically faster processing:
+
+- **Without optimization:** 10-15 minutes for full pipeline
+- **With Rosetta 2:** ~4 minutes for full pipeline
+- **Improvement:** 4-6x faster
+
+See [macOS ARM64 Optimization Guide](docs/MACOS-ARM64-OPTIMIZATION.md) for setup instructions.
+
+### Speed Comparison
+
+| Method | Command Latency | Container Startup |
+|--------|----------------|-------------------|
+| **vicar-native-toolkit** | ~50-100ms | 0ms (persistent) |
+| docker run (per-command) | ~50-100ms | ~500-1000ms |
+| Native binary | ~10-20ms | 0ms |
+
+**Advantage:** 10-30x faster than `docker run` per command!
+
+### Optimize Stereo Processing
+
+**Use windowed/subframe images:**
+```bash
+# 1280x960 subframe: ~5-10 minutes
+# 5120x3840 full-res: ~30-60 minutes
+```
+
+**Adjust correlation parameters:**
+```bash
+# Faster (lower quality)
+marscorr \( left.vic right.vic \) disp.img \
+  template=11 search=31  # Smaller templates = faster
+
+# Slower (higher quality)
+marscorr \( left.vic right.vic \) disp.img \
+  template=21 search=71  # Larger templates = better
+```
+
+### Parallel Processing
+
+```bash
+# Process multiple stereo pairs in parallel
+marscorr \( pair1_left.vic pair1_right.vic \) disp1.img &
+marscorr \( pair2_left.vic pair2_right.vic \) disp2.img &
+marscorr \( pair3_left.vic pair3_right.vic \) disp3.img &
+wait
+```
+
+## Architecture
+
+### How It Works
+
+```
+User types: marsmesh inp=data.xyz out=mesh.obj
+     ↓
+Shell finds: .direnv/wrappers/marsmesh (symlink)
+     ↓
+Points to: .direnv/vicar-exec
+     ↓
+vicar-exec detects command: "marsmesh" (from $0)
+     ↓
+Runs: docker exec -i vicar-sidecar marsmesh inp=data.xyz out=mesh.obj
+     ↓
+Container executes: /usr/local/bin/marsmesh
+     ↓
+Output returns: to user terminal
+```
+
+**Key advantages:**
+- ✓ Single wrapper script for all commands
+- ✓ Symlink-based routing (fast, ~1MB disk)
+- ✓ Persistent container (no startup delay)
+- ✓ Transparent to user (no Docker syntax)

+
+## Example Workflows
+
+### Workflow 1: Quick Test with Pre-computed XYZ
+
+```bash
+cd vicar-native-toolkit
+direnv allow
+cd workspace
+
+# Copy existing XYZ and texture
+cp /data/mars/pointcloud.xyz .
+cp /data/mars/texture_image.vic texture.vic
+
+# Generate mesh (fast!)
+marsmesh inp=pointcloud.xyz out=terrain.obj \
+  in_skin=texture.vic \
+  x_subsample=2 y_subsample=2  # Downsample for speed
+
+# View
+meshlab terrain.obj
+```
+
+**Time:** ~30 seconds
+
+### Workflow 2: Full Pipeline from Stereo Pair
+
+```bash
+cd vicar-native-toolkit/workspace
+
+# Copy stereo images
+cp /data/mars/NLF_*01_195J01.VIC left.vic
+cp /data/mars/NLF_*04_195J01.VIC right.vic
+
+# Run pipeline

-# VICAR Native Toolkit - Demo Commands
-
-Demonstration of native-like command execution using direnv and wrapper scripts. VICAR commands execute inside a Docker container but feel like they're running natively on your system - no `docker-compose exec` or `docker exec` prefix needed!
-
-## Prerequisites
-
-- Docker Engine 20.10+ or Docker Desktop
-- direnv installed (`sudo apt install direnv` on Linux, `brew install direnv` on macOS)
-- Shell hook configured (add `eval "$(direnv hook bash)"` to ~/.bashrc or ~/.zshrc)
-- Access to terrain-intelligence-generator image
-
-## Image Setup
-
-```bash
-# Navigate to toolkit directory
-cd /path/to/tig/vicar-native-toolkit
-
-# Check if terrain-intelligence-generator image is available
-docker images | grep terrain-intelligence-generator
-
-# If not available, pull from GitHub Container Registry
-docker pull ghcr.io/nasa-ammos/tig/terrain-intelligence-generator:opensource
-```
-
----
-
-## Step 1: Activate the Toolkit
-
-```bash
-# Allow direnv to activate the environment
-direnv allow
-```
-
-**Expected Output:**
-```
-[vicar-toolkit] Activating VICAR Native Toolkit...
-[vicar-toolkit] Image: ghcr.io/nasa-ammos/tig/terrain-intelligence-generator:opensource
-[vicar-toolkit] Creating new container 'vicar-sidecar'...
-[vicar-toolkit] Container started successfully
-[vicar-toolkit] Auto-discovering VICAR commands...
-[vicar-toolkit] Found 545 commands
-[vicar-toolkit] Generated 545 wrapper scripts
-[vicar-toolkit] ✅ Toolkit activated! VICAR commands now available.
-```
-
----
-
-## Step 2: Navigate to Workspace
-
-```bash
-# Enter the workspace directory
-cd workspace
-```
-
-All VICAR commands must be run from within the `workspace/` directory or its subdirectories.
-
----
-
-## Step 3: Test Basic VICAR Commands
-
-Now you can use VICAR commands directly, as if they were installed natively!
-
-```bash
-# Generate test image (64x64 pixels)
-gen test.vic 64 64
-
-# List the file
-ls -lh test.vic
-
-# Generate larger test image (512x512 pixels)
-gen large.vic 512 512
-
-# Check both files
-ls -lh *.vic
-```
-
-**Expected Output:**
-```
-Beginning VICAR task GEN
-GEN Version 2019-05-28
-GEN task completed
-```
-
-**Key Feature:** No `docker-compose exec` or `docker exec` needed! Commands work like native CLI tools.
-
----
-
-## Step 4: Test Image Operations
-
-```bash
-# Copy image
-copy test.vic test_copy.vic
-
-# Stretch image contrast
-stretch test.vic stretched.vic
-
-# List all VICAR images
-ls -lh *.vic
-```
-
----
-
-## Step 5: Test vicario Converter
-
-Convert VICAR images to common formats:
-
-```bash
-# Convert to PNG
-vicario test.vic test.png
-
-# Convert to JPEG
-vicario test.vic test.jpg
-
-# Convert to TIFF
-vicario test.vic test.tiff
-
-# Verify conversions
-ls -lh test.*
-```
-
-**Expected Output:**
-```
-Converting test.vic to intermediate format...
-Reading pixel data...
-   Image dimensions: 64 x 64
-Writing .PNG file...
-✅ Success: test.png (99 bytes)
-   Dimensions: 64 x 64
-```
-
----
-
-## Step 6: Verify MARS Commands
-
-MARS commands are available as native-like wrappers:
-
-```bash
-# Test a MARS command exists
-marsmap --help 2>&1 | head -5
-
-# Or check specific commands work
-type marsmap
-type marscorr
-type marsxyz
-```
-
-**Note:** 74 MARS commands are available. You can list them from the toolkit root with:
-```bash
-cd ..
-ls .direnv/wrappers | grep "^mars" | head -20
-cd workspace
-```
-
----
-
-## Step 7: Check Toolkit Status
-
-```bash
-# Check toolkit status
-toolkit-status
-```
-
-**Expected Output:**
-```
-VICAR Native Toolkit Status:
-  Container: vicar-sidecar
-  Status: Up X minutes
-  Wrappers: 549 commands
-  Image: ghcr.io/nasa-ammos/tig/terrain-intelligence-generator:opensource
-```
-
----
-
-## Step 8: Interactive Container Shell (Optional)
-
-Enter the container for direct interaction:
-
-```bash
-# Open interactive shell
-toolkit-shell
-
-# Inside container, run commands:
-cd /workspace
-gen interactive.vic 256 256
-label interactive.vic
-exit
-
-# Files persist on host
-ls -lh interactive.*
-```
-
----
-
-### Step 9: Leave Directory (Deactivate)
-
-```bash
-# Go back to parent directory
-cd ../..
-```
-
-When you leave the `vicar-native-toolkit` directory, the wrapper commands are automatically removed from your PATH. The container keeps running in the background.
-
----
-
-### Step 10: Re-enter Directory (Reactivate)
-
-```bash
-# Re-enter toolkit directory
-cd vicar-native-toolkit
-
-# Commands are instantly available again!
-cd workspace
-gen another.vic 512 512
-```
-
-The container is already running, so activation is instantaneous.
-
----
-
-## Cleanup
-
-### Stop Container
-
-```bash
-# From vicar-native-toolkit directory
-toolkit-stop
-```
-
-### Restart Container
-
-```bash
-# Stop and remove container (will be recreated on next activation)
-toolkit-restart
-
-# Leave and re-enter directory
-cd .. && cd vicar-native-toolkit
-```
-
----
-
-## Summary - Native-like Commands
-
-### What You Learned
-
-✅ Activate toolkit with `direnv allow`  
-✅ Use VICAR commands directly (no docker prefix)  
-✅ Commands work from `workspace/` directory  
-✅ Files persist on host automatically  
-✅ Leave directory to deactivate, re-enter to reactivate  
-
-### Key Benefits
-
-1. **Native feel**: Commands work like locally installed tools
-2. **Fast**: Container stays running, no startup overhead
-3. **Automatic**: direnv activates/deactivates on directory entry/exit
-4. **Transparent**: 545 commands available instantly
-5. **Persistent**: Workspace files always accessible on host
-
----
-
-## Time Estimate
-
-- Initial setup (direnv install): 2-3 minutes
-- Image pull (if needed): 5-10 minutes
-- Demo execution: 3-5 minutes
-- **Total: 10-18 minutes (5-8 if image already available)**

-# Mounting Camera Models and External Data
-
-This guide explains how to mount camera models, calibration files, mission data, and other external directories into the VICAR Native Toolkit container.
-
-## Quick Start
-
-### 1. Identify Your Data Locations
-
-Camera models and calibration data are typically stored in:
-
-- **V2CONFIG_PATH**: VICAR configuration path (camera models, .cahv/.cahvor files)
-- **Mission Data**: Mars mission data (images, EDRs, RDRs)
-- **Pointing Files**: Mars pointing files (usually in `/proj/mars/def` on JPL systems)
-
-### 2. Edit `.envrc` Configuration
-
-Open `.envrc` and uncomment/configure the data mount variables:
-
-```bash
-# ===== Camera Models and Calibration Data =====
-# Uncomment and configure these paths to mount camera models and calibration data
-CAMERA_MODELS_DIR="${V2CONFIG_PATH:-/path/to/camera/models}"  # Camera calibration files
-MISSION_DATA_DIR="/data/missions"                              # Mission data (read-only)
-POINT_FILES_DIR="/proj/mars/def"                               # Mars pointing files
-```
-
-### 3. Configure Your Paths
-
-#### Option A: Use Environment Variables (Recommended)
-
-Set environment variables in your shell profile (`~/.bashrc`, `~/.zshrc`):
-
-```bash
-# Add to ~/.zshrc or ~/.bashrc
-export V2CONFIG_PATH="/path/to/your/camera/models"
-export MISSION_DATA_PATH="/data/missions"
-export POINT_FILES_PATH="/proj/mars/def"
-```
-
-Then update `.envrc`:
-
-```bash
-CAMERA_MODELS_DIR="${V2CONFIG_PATH}"
-MISSION_DATA_DIR="${MISSION_DATA_PATH}"
-POINT_FILES_DIR="${POINT_FILES_PATH}"
-```
-
-#### Option B: Hardcode Paths in `.envrc`
-
-```bash
-CAMERA_MODELS_DIR="/Users/han/vicar/config"
-MISSION_DATA_DIR="/Users/han/data/missions"
-POINT_FILES_DIR="/Users/han/mars/pointing"
-```
-
-### 4. Restart the Environment
-
-```bash
-# Stop existing container
-docker stop vicar-sidecar && docker rm vicar-sidecar
-
-# Re-enter directory to restart with new mounts
-cd .. && cd -
-
-# Or reload direnv
-direnv reload
-```
-
-## Mount Points Inside Container
-
-When configured, your data will be mounted at:
-
-| Host Path | Container Path | Purpose |
-|-----------|----------------|---------|
-| `$CAMERA_MODELS_DIR` | `/vicar/config` | Camera models (.cahv, .cahvor files) |
-| `$MISSION_DATA_DIR` | `/data/missions` | Mission data (images, EDRs) |
-| `$POINT_FILES_DIR` | `/proj/mars/def` | Mars pointing files |
-| `$WORKSPACE_ROOT` | `/workspace` | Your working directory |
-
-## Common Use Cases
-
-### Mounting Camera Models for Mars Processing
-
-```bash
-# In .envrc, add:
-CAMERA_MODELS_DIR="/proj/mars/config"
-
-# Container will have access to:
-# /vicar/config/*.cahv
-# /vicar/config/*.cahvor
-# /vicar/config/m20/*.cahv
-```
-
-Then in your VICAR commands:
-
-```bash
-# Commands will automatically find camera models
-marsmap input.img output.map CAHVOR=/vicar/config/m20/camera.cahvor
-```
-
-### Mounting Read-Only Mission Data
-
-For large datasets you don't want to copy:
-
-```bash
-# In .envrc:
-MISSION_DATA_DIR="/Volumes/MissionData/M2020/sols"
-
-# Access in commands:
-marsmos /data/missions/sol_00123/*.img output.mosaic
-```
-
-### Mounting Multiple Directories
-
-You can add custom mounts by editing the `docker run` command in `.envrc`:
-
-```bash
-# Find the docker run command (around line 92-100) and add more volumes:
-docker run -d \
-    --name "${CONTAINER_NAME}" \
-    ${net_args} \
-    ${volume_args} \
-    -v "/custom/data:/custom/data:ro" \
-    -v "/scratch:/scratch" \
-    ${x11_args} \
-    -w /workspace \
-    "${CONTAINER_IMAGE}" \
-    tail -f /dev/null
-```
-
-## Mount Options
-
-### Read-Only vs Read-Write
-
-- **Read-only** (`:ro`): Prevents accidental modification of source data
-- **Read-write** (default): Allows writing
-
-```bash
--v "/source:/dest:ro"    # Read-only
--v "/source:/dest"       # Read-write
-```
-
-**Recommendation**: Mount calibration data and mission archives as read-only.
-
-### Symbolic Links
-
-If your data contains symbolic links, Docker will follow them if:
-
-1. The symlink target is within the mounted volume
-2. The symlink target is in another mounted volume
-3. On macOS, symlink resolution may be slower due to VM layer
-
-## Verification
-
-### Check Mounted Volumes
-
-```bash
-# Enter container
-toolkit-shell
-
-# List mounted directories
-ls -la /vicar/config
-ls -la /data/missions
-ls -la /proj/mars/def
-
-# Verify camera models
-find /vicar/config -name "*.cahv*" | head -10
-
-# Exit
-exit
-```
-
-### Test with VICAR Commands
-
-```bash
-# Test marsmap with camera model
-cd workspace
-marsmap input.img output.map
-
-# Check if camera models are found
-label output.map | grep CAHV
-```
-
-## Troubleshooting
-
-### "Permission denied" Errors
-
-On Linux, ensure your user has read access:
-
-```bash
-ls -la /path/to/camera/models
-# Should show readable permissions
-```
-
-If needed, adjust permissions:
-
-```bash
-chmod -R a+rX /path/to/camera/models
-```
-
-### Mounts Not Visible in Container
-
-1. Check if the directory exists on host:
-   ```bash
-   ls -la "${CAMERA_MODELS_DIR}"
-   ```
-
-2. Stop and remove container:
-   ```bash
-   docker stop vicar-sidecar && docker rm vicar-sidecar
-   ```
-
-3. Re-enter directory:
-   ```bash
-   cd .. && cd -
-   ```
-
-4. Verify mounts:
-   ```bash
-   docker inspect vicar-sidecar | grep Mounts -A 20
-   ```
-
-### macOS Performance Issues
-
-Docker on macOS uses a VM layer, which can slow down file I/O:
-
-**Solutions**:
-- Enable VirtioFS in Docker Desktop (Settings → General → VirtioFS)
-- For large datasets, copy frequently-used files to `workspace/` instead
-- Use `:cached` or `:delegated` mount options for performance:
-  ```bash
-  -v "/data:/data:ro,cached"
-  ```
-
-### Camera Models Not Found by VICAR
-
-VICAR looks for camera models in specific environment variables:
-
-1. Check container environment:
-   ```bash
-   toolkit-shell
-   env | grep -i config
-   env | grep -i vicar
-   ```
-
-2. Set environment variables in `.envrc`:
-   ```bash
-   # After the docker run command, add:
-   export V2CONFIG_PATH="/vicar/config"
-   ```
-
-3. Or pass to individual commands:
-   ```bash
-   docker exec -e V2CONFIG_PATH=/vicar/config vicar-sidecar marsmap ...
-   ```
-
-## Examples
-
-### Example 1: Mount Local Camera Models
-
-```bash
-# Host structure:
-# ~/mars/calibration/
-#   ├── m20/
-#   │   ├── zcam_left.cahvor
-#   │   └── zcam_right.cahvor
-#   └── msl/
-#       └── mastcam.cahv
-
-# In .envrc:
-CAMERA_MODELS_DIR="${HOME}/mars/calibration"
-
-# In container:
-# /vicar/config/m20/zcam_left.cahvor
-# /vicar/config/msl/mastcam.cahv
-```
-
-### Example 2: Mount JPL Network Paths
-
-```bash
-# On JPL network (Linux):
-CAMERA_MODELS_DIR="/proj/mars/config"
-MISSION_DATA_DIR="/proj/mars/m2020/data"
-POINT_FILES_DIR="/proj/mars/def"
-
-# Access in container:
-marsmap /data/missions/sol_00001/*.img output.map
-```
-
-### Example 3: Mount S3 or Network Drives
-
-```bash
-# Mount network drive first (macOS):
-# Finder → Go → Connect to Server → smb://server/share
-
-# Then mount into container:
-MISSION_DATA_DIR="/Volumes/MarsData"
-
-# Or on Linux with CIFS:
-# sudo mount -t cifs //server/share /mnt/mars
-
-MISSION_DATA_DIR="/mnt/mars"
-```
-
-## Environment Variables
-
-VICAR tools look for these environment variables:
-
-| Variable | Purpose | Typical Value |
-|----------|---------|---------------|
-| `V2CONFIG_PATH` | Camera calibration files | `/vicar/config` |
-| `V2TOP` | VICAR installation root | `/usr/local/vicar/dev` |
-| `MARS_CONFIG_PATH` | Mars-specific config | `/vicar/config/mars` |
-| `POINT_METHOD` | Pointing correction method | `SPICE` or `PLACES` |
-
-Set these in the container by adding to `.envrc` after the `docker run` command:
-
-```bash
-# After container starts, export variables
-docker exec vicar-sidecar bash -c "echo 'export V2CONFIG_PATH=/vicar/config' >> /etc/bashrc"
-```
-
-Or set them when running commands:
-
-```bash
-docker exec -e V2CONFIG_PATH=/vicar/config vicar-sidecar marsmap ...
-```
-
-## Advanced: Dynamic Mounts
-
-For frequently changing data locations:
-
-```bash
-# In .envrc, add a function to prompt for paths:
-_mount_custom_data() {
-    read -p "Enter camera models path: " CAMERA_MODELS_DIR
-    export CAMERA_MODELS_DIR
-}
-
-# Call before starting container
-# _mount_custom_data
-```
-

-
-## Summary
-
-1. Identify your data paths (camera models, mission data, etc.)
-2. Edit `.envrc` to configure `CAMERA_MODELS_DIR`, `MISSION_DATA_DIR`, etc.
-3. Uncomment the configuration lines
-4. Restart the container: `docker stop vicar-sidecar && docker rm vicar-sidecar`
-5. Re-enter directory: `cd .. && cd -`
-6. Verify: `toolkit-shell` then `ls /vicar/config`
-
-Your camera models are now accessible to all VICAR commands!

 - **Smart bind-mounts** - Single workspace mount with intelligent CWD resolution
 
+### Wrapper Architecture
+
+Instead of generating 500+ individual wrapper scripts, the toolkit uses a symlink-based approach:
+
+1. **Single wrapper script** (`vicar-exec`) - Handles all VICAR commands
+2. **Command detection** - Auto-discovers available commands from container
+3. **Symlink generation** - Creates symlinks pointing to `vicar-exec` for each command
+4. **Dynamic routing** - `vicar-exec` determines which command to run based on symlink name
+
+**Benefits:**
+- Faster activation (~1 second vs 3-5 seconds)
+- Reduced disk usage (~2MB vs 3.5MB)
+- Single point of maintenance
+- Identical functionality
+
 ### Performance
 
 - **Command latency**: ~50-100ms on Linux, ~80-150ms on macOS
 - **vs. docker run**: 10-30x faster than per-command containers
 - **vs. native**: Slight overhead, but allows consistent environment across platforms
 
+**macOS Apple Silicon Optimization:**
+For M1/M2/M3 Macs, enable Rosetta 2 for 4-6x faster processing. See [macOS ARM64 Optimization Guide](docs/MACOS-ARM64-OPTIMIZATION.md) for details.

-# VICAR Native Toolkit Walkthrough - Complete Setup for TIG Demo
-
-**Goal:** Set up vicar-native-toolkit to work with the M20-G87 VICAR build for native-like command execution in the TIG demo.
-
-**Time:** ~15-20 minutes (mostly building Docker images)
-
----
-
-## Prerequisites
-
-Before starting, ensure you have:
-
-- ✅ **Docker Desktop** installed and running
-- ✅ **direnv** installed (`brew install direnv` on macOS, `apt install direnv` on Linux)
-- ✅ **Shell configured** with direnv hook (see below)
-- ✅ **~5GB free disk space** for Docker images
-- ✅ **XQuartz** (macOS only) for X11 forwarding
-
-### Configure direnv in Your Shell
-
-Add to your shell config file (`~/.zshrc` for zsh, `~/.bashrc` for bash):
-
-```bash
-# For bash
-eval "$(direnv hook bash)"
-
-# For zsh
-eval "$(direnv hook zsh)"
-```
-
-Then reload your shell:
-```bash
-source ~/.zshrc  # or source ~/.bashrc
-```
-
----
-
-## Step 1: Navigate to Project
-
-```bash
-cd /Users/han/IdeaProjects/MIPL/vicar/vicar-native-toolkit
-```
-
-**Verify location:**
-```bash
-pwd
-ls -la
-# Should show: .envrc, docker/, scripts/, workspace/, etc.
-```
-
----
-
-## Step 2: Build the TIG Demo Docker Image
-
-The TIG demo image extends the base VICAR image with Python dependencies (numpy, scipy, Pillow).
-
-```bash
-# Build the TIG demo image
-./scripts/build-tig-demo-image.sh
-```
-
-**Expected output:**
-```
-✅ Build successful!
-Image created: vicar-tools:tig-demo
-Size: ~1.36GB
-```
-
-**Time:** ~3-5 minutes
-
-**Verify image built:**
-```bash
-docker images | grep vicar-tools:tig-demo
-```
-
-Should show:
-```
-vicar-tools:tig-demo    latest    <image-id>    1.36GB
-```
-
----
-
-## Step 3: Review Configuration (Optional)
-
-The toolkit comes with a default configuration for the TIG demo image. Review it:
-
-```bash
-cat .envrc.config
-```
-
-**Key settings you'll see:**
-- `CONTAINER_IMAGE="vicar-tools:tig-demo"` - Uses the TIG demo image
-- `VICAR_INSTALL_PREFIX="/usr/local/vicar/m20-g87"` - M20-G87 RPM build paths
-- `AUTO_DISCOVER_TOOLS=true` - Automatically finds all VICAR commands
-- `PARENT_DIR` mount - Makes `../project/` accessible as `/projects/` in container
-
-**This configuration is ready to use!** No changes needed.
-
----
-
-## Step 4: Activate the Toolkit
-
-Now activate the toolkit with direnv:
-
-```bash
-direnv allow
-```
-
-**What happens:**
-1. 📝 Loads configuration from `.envrc.config`
-2. 🔧 Detects your platform (macOS/Linux)
-3. 📦 Starts `vicar-sidecar` container with TIG demo image
-4. 📁 Mounts workspace and parent directory
-5. 🔨 Discovers and generates wrappers for ~700+ VICAR commands
-6. ✅ Adds wrappers to your PATH
-
-**Expected output:**
-```
-📝 Loading configuration from .envrc.config
-🔧 VICAR Native Toolkit - Darwin detected
-   Image: vicar-tools:tig-demo
-   Container: vicar-sidecar
-📦 Starting vicar-sidecar container...
-📁 Mounting parent directory: /Users/han/IdeaProjects/MIPL/vicar -> /projects
-✅ Container started successfully
-🔨 Generating wrapper scripts...
-🔍 Auto-discovering VICAR executables...
-✅ Found XXX executables
-
-✅ VICAR Native Toolkit activated!
-
-Available commands:
-  toolkit-status    - Show configuration and container status
-  toolkit-shell     - Open interactive shell in container
-  toolkit-stop      - Stop and remove container
-  toolkit-restart   - Restart container with new configuration
-
-VICAR tools: XXX commands available
-Working directory: /Users/han/IdeaProjects/MIPL/vicar/vicar-native-toolkit/workspace
-```
-
-**Time:** ~30-60 seconds
-
----
-
-## Step 5: Verify Wrapper Generation
-
-If auto-discovery found 0 tools (due to timing), manually generate wrappers:
-
-```bash
-# Check current wrappers
-ls .direnv/wrappers/ | wc -l
-```
-
-**If less than 700 wrappers**, regenerate them:
-
-```bash
-# Clean and regenerate
-rm -rf .direnv/wrappers/*
-./.direnv/generate-wrappers.sh
-```
-
-**Expected output:**
-```
-Discovering executables...
-Found 782 executables, generating wrappers...
-  Generated 100 wrappers...
-  Generated 200 wrappers...
-  ...
-  Generated 700 wrappers...
-✅ Generated 782 wrappers in .direnv/wrappers
-```
-
-**Verify critical commands:**
-```bash
-ls .direnv/wrappers/ | grep -E "^(gen|label|hist|marscorr|marsxyz)$"
-```
-
-Should show all 5 commands.
-
----
-
-## Step 6: Test Native Command Execution
-
-Test that commands work like native CLI tools:
-
-### Test 1: Basic VICAR Command
-
-```bash
-cd workspace
-
-# Generate a test image (NO Docker syntax!)
-gen out=test.vic nl=512 ns=512
-```
-
-**Expected output:**
-```
-Beginning VICAR task GEN
-GEN Version 2019-05-28
-GEN task completed
-```
-
-**✅ Success!** The `gen` command worked like a native CLI tool.
-
-### Test 2: View Histogram
-
-```bash
-hist inp=test.vic
-```
-
-**Expected output:**
-```
-Beginning VICAR task HIST
-*** HIST version 2017-08-08 ***
-
-Bin Width = 1.0
-  0    1
-  1    2  *
-  2    3  *
-  ...
-```
-
-**✅ Success!** Commands work without any Docker syntax.
-
-### Test 3: Check Container Status
-
-```bash
-toolkit-status
-```
-
-**Expected output:**
-```
-======================================================================
-VICAR Native Toolkit Status
-======================================================================
-
-Container: vicar-sidecar
-Image: vicar-tools:tig-demo
-Status: running
-
-Mounts:

-  /Users/han/IdeaProjects/MIPL/vicar -> /projects
-
-Wrappers: XXX commands in .direnv/wrappers
-
-VICAR Paths (inside container):
-  BIN: /usr/local/bin:/usr/local/vicar/m20-g87/p2/lib/x86-64-linx:/usr/local/vicar/m20-g87/mars/lib/x86-64-linx:...
-  LIB: /usr/local/vicar/m20-g87/olb/x86-64-linx:/usr/local/vicar/m20-g87/mars/lib/x86-64-linx:...
-```
-
-**✅ Success!** Toolkit is configured and running.
-
----
-
-## Step 7: Verify Mars Commands
-
-Test that Mars processing commands are available:
-
-```bash
-# Check if Mars commands exist
-ls .direnv/wrappers/ | grep ^mars | head -10
-```
-
-**Expected output:**
-```
-marscorr
-marsdisparity
-marsmap
-marsrad
-marstie
-marsxyz
-...
-```
-
-### Test Mars Command Wrapper
-
-```bash
-# Test that marscorr wrapper exists and is executable
-which marscorr
-cat $(which marscorr) | head -20
-```
-
-**Expected output:**
-```
-/Users/han/IdeaProjects/MIPL/vicar/vicar-native-toolkit/.direnv/wrappers/marscorr
-
-#!/usr/bin/env bash
-# Wrapper for: marscorr
-
-TTY_FLAG=""
-[ -t 0 ] && [ -t 1 ] && TTY_FLAG="-t"
-
-exec docker exec -i ${TTY_FLAG} \
-    -e DISPLAY=host.docker.internal:0 \
-    -e PATH="/usr/local/bin:..." \
-    -e LD_LIBRARY_PATH="/usr/local/vicar/m20-g87/..." \
-    -w /workspace \
-    "vicar-sidecar" \
-    marscorr "$@"
-```
-
-**✅ Success!** Mars commands have native-like wrappers.
-
----
-
-## Step 8: Prepare for TIG Demo
-
-Now set up access to the TIG demo directory:
-
-```bash
-# Create symlink to demo directory (if not already present)
-cd workspace
-ln -sf ../../vicar-tig-demo demo
-ls -la demo
-```
-
-**Verify access:**
-```bash
-# Check that demo files are accessible from container
-docker exec vicar-sidecar ls -la /workspace/demo 2>&1 | head -5
-```
-
-**Note:** Due to mount limitations, you may need to copy demo data to workspace or access via the `/projects` mount.
-
-### Option A: Copy Demo Data to Workspace
-
-```bash
-cd workspace
-cp -r ../../vicar-tig-demo/data/input/edrs/ ./edrs/
-ls -lh edrs/
-```
-
-### Option B: Access via /projects Mount
-
-The parent directory is mounted at `/projects`, so:
-- Host: `/Users/han/IdeaProjects/MIPL/vicar/vicar-tig-demo/data/input/edrs/`
-- Container: `/projects/vicar-tig-demo/data/input/edrs/`
-
----
-
-## Step 9: Test with Real M20 EDR Files
-
-Copy one EDR stereo pair to workspace for testing:
-
-```bash
-cd workspace
-
-# Copy EDR files
-cp ../../vicar-tig-demo/data/input/edrs/NRF_1812_0827803370_941EDR_N0870268NCAM02812_01_195J01.VIC left_edr.vic
-cp ../../vicar-tig-demo/data/input/edrs/NRF_1812_0827803370_941EDR_N0870268NCAM02812_04_195J01.VIC right_edr.vic
-
-ls -lh *_edr.vic
-```
-
-**Expected output:**
-```
--rw-r--r--  1 han  staff   7.2M  left_edr.vic
--rw-r--r--  1 han  staff   7.2M  right_edr.vic
-```
-
-### Test Label Command (Mars Metadata)
-
-```bash
-# This will show TAE subcommand error, but proves command works
-label left_edr.vic 2>&1 | head -5
-```
-
-**Expected output:**
-```
-[TAE-SUBREQ] Subcommand is required for 'LABEL'.
-```
-
-**✅ This is expected!** VICAR's label command requires subcommands. The wrapper is working.
-
----

-The TIG demo scripts will automatically use the wrappers:
-
-```bash
-cd ../vicar-tig-demo
-
-# Stage 2: Stereo Matching (uses marscorr wrapper internally)
-python3 scripts/02-stereo-match.py \
-  --left data/input/edrs/NRF_1812_0827803370_941EDR_N0870268NCAM02812_01_195J01.VIC \
-  --right data/input/edrs/NRF_1812_0827803370_941EDR_N0870268NCAM02812_04_195J01.VIC \
-  --output data/cache/disparity.vic \
-  -v
-```
-
-The Python script calls `subprocess.run(["marscorr", ...])` which finds the wrapper on PATH!
-
-### Option 2: Run Commands Directly (Native Style)
-
-```bash
-cd vicar-native-toolkit/workspace
-
-# Direct command usage (native style!)
-gen out=left_small.vic nl=400 ns=400
-gen out=right_small.vic nl=400 ns=400
-
-# Resize EDR files
-size inp=left_edr.vic out=left_small.vic nl=400 ns=400
-size inp=right_edr.vic out=right_small.vic nl=400 ns=400
-
-# Run stereo correlation (may take several minutes)
-marscorr inp=(left_small.vic,right_small.vic) out=disparity.vic
-```
-
-**No Docker syntax needed!** Commands work like native CLI tools.
-

-
-## Reference: Key Commands
-
-### Toolkit Management
-
-```bash
-toolkit-status     # Show configuration and container status
-toolkit-shell      # Open interactive shell in container
-toolkit-restart    # Restart container
-toolkit-stop       # Stop and remove container
-```
-
-### Container Operations
-
-```bash
-# Check container
-docker ps | grep vicar-sidecar
-
-# View logs
-docker logs vicar-sidecar
-
-# Execute command in container
-docker exec vicar-sidecar <command>
-```
-
-### Wrapper Inspection
-
-```bash
-# List all wrappers
-ls .direnv/wrappers/
-
-# View wrapper implementation
-cat .direnv/wrappers/marscorr
-
-# Check command availability
-which gen hist marscorr
-```
-

-
-## Architecture Diagram
-
-```
-User Command (e.g., "marscorr ...")
-         ↓
-Shell finds wrapper on PATH
-         ↓
-~/.direnv/wrappers/marscorr
-         ↓
-docker exec vicar-sidecar marscorr ...
-         ↓
-Long-running container (fast!)
-         ↓
-VICAR command executes
-         ↓
-Result returns to user
-```
-
-**Key Point:** User never sees Docker syntax - it all happens transparently!
-
----
-
-## Summary
-
-You've successfully set up vicar-native-toolkit to provide **native-like command execution** for 700+ VICAR commands including all Mars processing tools. The toolkit:
-
-- ✅ **Feels native** - No Docker syntax in user commands
-- ✅ **Works fast** - Long-running container (~50-100ms latency)
-- ✅ **Supports M20-G87** - RPM-based VICAR build with Mars tools
-- ✅ **Auto-discovers commands** - 700+ wrappers generated automatically
-- ✅ **Python-friendly** - Scripts just call commands via subprocess
-- ✅ **Demo-ready** - All components tested and validated
-
-**Ready to run the TIG demo with native-like VICAR commands!** 🚀

 ## Overview
 
-The VICAR Native Toolkit now supports **configurable VICAR images**, allowing you to use any VICAR build including:
-- **RPM-based builds** (M20-G87, etc.)
-- **Source-built images** (development)
+The VICAR Native Toolkit supports **configurable VICAR images**, allowing you to use:
+- **Open-source builds** (ghcr.io/nasa-ammos/tig/terrain-intelligence-generator:opensource)
 - **Custom images** with specific configurations
+- **Local builds** with modified VICAR installations
+
+Configuration is managed through `.envrc.local` for easy customization without editing tracked files.
 
 ## Quick Start
 
-### 1. Choose Your Configuration
+### Using Bootstrap (Recommended)
 
-Copy the example configuration and customize it:
+The easiest way to configure the toolkit:
 
 ```bash
-cp .envrc.config.example .envrc.local
-# Edit .envrc.local for your setup
+# Default opensource image
+./bootstrap.sh
+
+# Custom image
+./bootstrap.sh --image myregistry/vicar:v2.0
+
+# With MARS calibration
+./bootstrap.sh --mars-calib /path/to/mars_calibration_m20
+
+# Custom container name
+./bootstrap.sh --container my-vicar
+
+# Config only (no image pull)
+./bootstrap.sh --config-only --image custom:tag
 ```
 
-### 2. Configure for Your Image
+The bootstrap script creates `.envrc.local` with your settings.
 
-The toolkit includes a default configuration for `vicar-tools:tig-demo` (M20-G87 RPM build). To use a different image, edit `.envrc.local`:
+### Manual Configuration
 
-```bash
-# Change the image
-CONTAINER_IMAGE="your-image:tag"
+Create `.envrc.local` manually:
 
-# Update paths to match your image's VICAR installation
-VICAR_INSTALL_PREFIX="/usr/local/vicar/your-build"
-VICAR_BIN_PATHS=(
-    "/usr/local/bin"
-    "${VICAR_INSTALL_PREFIX}/p2/lib/x86-64-linx"
-)
+```bash
+cp .envrc.config.example .envrc.local
+# Edit .envrc.local with your settings
 ```
 
-### 3. Activate
+Then activate:
 
 ```bash
 direnv allow
-# Container starts, wrappers generate, commands work natively!
+# Container starts, wrappers generate, commands available!
 ```
 
 ## Configuration Files
 
 ### Priority Order
 
-1. **`.envrc.local`** (gitignored) - Your personal configuration
-2. **`.envrc.config`** (tracked) - Project default configuration  
-3. **`.envrc.config.example`** - Template with all options
+1. **`.envrc.local`** (gitignored) - Your personal configuration (created by bootstrap or manually)
+2. **`.envrc.config`** (tracked) - Project default configuration (if exists)
+3. **`.envrc`** - Main activation script with defaults
 
 ### File Purposes
 
 | File | Purpose | Tracked |
 |------|---------|---------|
-| `.envrc` | Main activation script (don't edit) | ✅ Yes |
-| `.envrc.config` | Project default (M20-G87) | ✅ Yes |
-| `.envrc.config.example` | Template with all options | ✅ Yes |
-| `.envrc.local` | Your personal overrides | ❌ No (gitignored) |
+| `.envrc` | Main activation script + defaults | ✅ Yes |
+| `.envrc.config` | Optional project defaults | ✅ Yes |
+| `.envrc.local` | Your personal config | ❌ No (gitignored) |
+| `bootstrap.sh` | Automated configuration generator | ✅ Yes |
+
+### Generated Files (gitignored)
+
+These are created automatically on activation:

+# Mounting MARS Calibration Data
+
+This guide explains how to mount MARS calibration files (camera models, flat fields, parameter files) into the VICAR Native Toolkit container.
+
+## Quick Start
+
+### 1. Set Environment Variable
+
+Set `MARS_CONFIG_PATH` to point to your calibration directory:
+
+```bash
+# Add to shell profile (~/.bashrc or ~/.zshrc)
+export MARS_CONFIG_PATH="${HOME}/.mars_calib"
+
+# Or set temporarily
+export MARS_CONFIG_PATH="/path/to/mars_calibration_m20"
+```
+
+### 2. Restart Container
+
+```bash
+cd vicar-native-toolkit
+toolkit-restart
+```
+
+### 3. Verify Calibration Mounted
+
+```bash
+toolkit-verify-calib
+```
+
+Expected output:
+```
+=== MARS Calibration Verification ===
+MARS_CONFIG_PATH: /usr/local/vicar/mars_calib
+
+Mount point exists: /usr/local/vicar/mars_calib
+Contents:
+drwxr-xr-x camera_models
+drwxr-xr-x flat_fields
+drwxr-xr-x param_files
+
+Camera models: 226
+Flat fields: 381
+Param files: 3
+```
+
+## Configuration Options
+
+### Option 1: Shell Environment Variable (Recommended)
+
+Set in your shell profile for persistent configuration:
+
+```bash
+# ~/.bashrc or ~/.zshrc
+export MARS_CONFIG_PATH="${HOME}/.mars_calib"
+```
+
+Then activate the toolkit:
+
+```bash
+cd vicar-native-toolkit
+direnv allow
+```
+
+### Option 2: Local Configuration File
+
+Copy and edit the configuration file:
+
+```bash
+cd vicar-native-toolkit
+cp .envrc.config.example .envrc.config
+```
+
+Edit `.envrc.config`:
+
+```bash
+# Uncomment and set your path
+MARS_CONFIG_PATH="${HOME}/.mars_calib"
+```
+
+Then activate:
+
+```bash
+direnv allow
+```
+
+### Option 3: Temporary Override
+
+Set for current shell session only:
+
+```bash
+export MARS_CONFIG_PATH="/tmp/test_calibration"
+cd vicar-native-toolkit
+direnv allow
+```
+
+## Calibration Directory Structure
+
+Your calibration directory should contain:
+
+```
+mars_calibration_m20/
+├── camera_models/
+│   ├── *.cahvor     # Camera geometry files
+│   └── *.cahvore    # Extended camera models

+└── param_files/
+    └── *.xml        # Camera mapping configuration
+```
+
+MARS tools (marsmap, marsmos, marsmesh) automatically discover files from these subdirectories using the `$MARS_CONFIG_PATH` environment variable.
+
+## Mount Behavior
+
+### When MARS_CONFIG_PATH is Set and Valid
+
+```bash
+export MARS_CONFIG_PATH="/opt/mars_calibration_m20"
+```
+
+**Result:**
+- Host path: `/opt/mars_calibration_m20`
+- Container path: `/usr/local/vicar/mars_calib` (read-only)
+- Container environment: `MARS_CONFIG_PATH=/usr/local/vicar/mars_calib`
+- Log: `[vicar-toolkit] Mounting MARS calibration: /opt/mars_calibration_m20`
+
+### When MARS_CONFIG_PATH is Set but Directory Missing
+
+```bash
+export MARS_CONFIG_PATH="/nonexistent/path"
+```
+
+**Result:**
+- Mount skipped
+- Container starts successfully
+- Log: `[vicar-toolkit] MARS_CONFIG_PATH set but directory not found: /nonexistent/path (skipping)`
+- MARS tools will fail if they require camera models
+
+### When MARS_CONFIG_PATH is Not Set
+
+```bash
+# unset MARS_CONFIG_PATH
+```
+
+**Result:**
+- Mount skipped silently
+- Container starts normally
+- No calibration available
+- Valid configuration for non-MARS workflows
+
+## Mount Details
+
+### Container Mount Point
+
+| Host Path | Container Path | Mount Options |
+|-----------|----------------|---------------|
+| `$MARS_CONFIG_PATH` | `/usr/local/vicar/mars_calib` | `ro,Z` (read-only, SELinux-safe) |
+
+### Environment Variable
+
+Inside the container, `MARS_CONFIG_PATH` is set to `/usr/local/vicar/mars_calib` automatically when calibration is mounted.
+
+MARS tools check this variable to locate:
+- Camera geometry files (`.cahvor`, `.cahvore`)
+- Radiometric correction data (flat field `.IMG` files)
+- Camera mapping XML files
+
+### Mount Options
+
+- **Read-only (`:ro`)**: Prevents accidental modification of calibration files
+- **SELinux-safe (`:Z`)**: Relabels files for container access on SELinux systems (Linux)
+- The `:Z` flag is safe on macOS and will be ignored if not needed
+
+## Configuration Examples
+
+### Example 1: TIG Repository Structure
+
+If you have the terrain-intelligence-generator repository cloned as a sibling:
+
+```bash
+# In .envrc.config
+MARS_CONFIG_PATH="${PWD}/../terrain-intelligence-generator/docker/mars_calibration_m20"
+```
+
+### Example 2: User Home Directory
+
+Store calibration in your home directory:
+
+```bash
+# In ~/.bashrc
+export MARS_CONFIG_PATH="${HOME}/.mars_calib"
+
+# Download/copy calibration files
+mkdir -p ~/.mars_calib
+# ... copy camera_models/, flat_fields/, param_files/ ...
+```
+
+### Example 3: System-Wide Installation
+
+For shared systems with calibration in `/opt`:
+
+```bash
+# In .envrc.config
+MARS_CONFIG_PATH="/opt/mars_calibration_m20"
+```
+
+### Example 4: Per-Mission Calibration
+
+Switch between missions using different paths:
+
+```bash
+# M2020
+export MARS_CONFIG_PATH="/data/mars/m2020/calibration"
+
+# MSL
+export MARS_CONFIG_PATH="/data/mars/msl/calibration"
+```
+
+## Verification
+
+### Using toolkit-verify-calib
+
+The built-in verification function checks calibration mount status:
+
+```bash
+toolkit-verify-calib
+```
+
+Output shows:
+1. Whether `MARS_CONFIG_PATH` is set
+2. Whether mount point exists
+3. Directory contents
+4. Count of camera models, flat fields, parameter files
+
+### Manual Verification
+
+Enter container shell:
+
+```bash
+toolkit-shell
+```
+
+Check environment and files:
+
+```bash
+# Check environment variable
+echo $MARS_CONFIG_PATH
+
+# List calibration directory
+ls -lh /usr/local/vicar/mars_calib/
+
+# Count camera models
+find /usr/local/vicar/mars_calib/camera_models -name "*.cahv*" | wc -l
+
+# Exit container
+exit
+```
+
+### Test with MARS Tools
+
+Run a MARS command that requires calibration:
+
+```bash
+cd workspace
+marsmap input.img output.map
+
+# If calibration is correct, marsmap will find camera models automatically
+```
+
+## Troubleshooting
+
+### "Directory not found" Warning
+
+**Symptom:**
+```
+[vicar-toolkit] MARS_CONFIG_PATH set but directory not found: /bad/path (skipping)
+```
+
+**Solution:**
+1. Verify path exists: `ls -la /bad/path`
+2. Fix typo in path
+3. Create directory if needed: `mkdir -p /correct/path`
+4. Restart container: `toolkit-restart`
+
+### "Permission denied" Error
+
+**Symptom:**
+```
+docker: Error response from daemon: error while creating mount source path: permission denied
+```
+
+**Solution:**
+Ensure your user has read access to the calibration directory:
+
+```bash
+# Check permissions
+ls -la /path/to/calibration
+
+# Fix if needed (Linux)
+chmod -R a+rX /path/to/calibration
+```
+
+### Empty Calibration Directory
+
+**Symptom:**
+```
+Camera models: 0
+Flat fields: 0
+Param files: 0
+```
+
+**Solution:**
+1. Verify host directory contains files: `ls -R $MARS_CONFIG_PATH`
+2. Ensure subdirectories exist: `camera_models/`, `flat_fields/`, `param_files/`
+3. Copy calibration files to correct subdirectories
+
+### MARS Tools Can't Find Camera Models
+
+**Symptom:**
+```
+[marsmap] Error: Unable to locate camera model file
+```
+
+**Solution:**
+1. Run `toolkit-verify-calib` to check mount status
+2. Verify `MARS_CONFIG_PATH` is set in container:
+   ```bash
+   docker exec vicar-sidecar bash -c 'echo $MARS_CONFIG_PATH'
+   ```
+3. Check file naming conventions (tools expect specific patterns)
+4. Verify files are in `camera_models/` subdirectory
+
+### Mount Not Visible After Configuration
+
+**Solution:**
+1. Container must be recreated for mount changes to take effect
+2. Stop container: `toolkit-stop`
+3. Re-enter directory: `cd .. && cd vicar-native-toolkit`
+4. Or use: `toolkit-restart` (requires re-entering directory)
+
+### macOS Specific Issues
+
+On macOS, Docker uses a VM layer:
+
+**Slow performance:**
+- Enable VirtioFS in Docker Desktop (Settings → General → VirtioFS)
+- For frequently-accessed files, consider copying to `workspace/` instead
+
+**Symlink issues:**
+- Ensure symlink targets are within mounted volume
+- Absolute symlinks may not resolve correctly
+
+## Platform Differences
+
+### Linux
+- SELinux systems (Fedora, RHEL, CentOS) require `:Z` flag (already included)
+- Direct filesystem access (faster than macOS)
+- May need permission adjustments for shared directories
+
+### macOS
+- Uses Docker Desktop VM
+- `:Z` flag is safely ignored
+- VirtioFS recommended for better performance
+- Network mounts (SMB, NFS) work but may be slower
+
+## Advanced: docker-compose.yml Configuration
+
+For docker-compose users, add calibration mount:
+
+```yaml
+volumes:
+  - ./workspace:/workspace:Z
+  - ${MARS_CONFIG_PATH}:/usr/local/vicar/mars_calib:ro,Z
+
+environment:
+  - MARS_CONFIG_PATH=/usr/local/vicar/mars_calib
+```
+
+Uncomment and customize for your setup.
+
+## Summary
+
+1. **Set `MARS_CONFIG_PATH`** environment variable to your calibration directory
+2. **Restart container** with `toolkit-restart`
+3. **Verify** with `toolkit-verify-calib`
+4. **Use MARS tools** - they will automatically find calibration files
+
+**Key points:**
+- Configuration is explicit - no auto-detection
+- Mount is read-only to protect source files
+- Container must be recreated for mount changes
+- Works identically on Linux and macOS
+- Non-MARS workflows work fine without calibration

+
+## Build Locally
+
+```bash
+cd vicar-native-toolkit
+./scripts/build-opensource-image.sh
+```
+
+## X11 Apps (Linux)
+
+```bash
+xhost +local:docker
+
+docker run -it --rm \
+  -v $(pwd)/data:/workspace \
+  -v /tmp/.X11-unix:/tmp/.X11-unix \
+  -e DISPLAY=$DISPLAY \
+  --network host \
+  ghcr.io/nasa-ammos/tig/vicar-native-toolkit:opensource \

+
+## Environment Check
+
+```bash
+# Inside container
+echo $V2TOP                    # /usr/local/vicar/vos
+echo $LD_LIBRARY_PATH          # VICAR library paths
+ls /usr/local/bin | head -20   # Available wrappers
+which label                    # /usr/local/bin/label
+```
+
+## Configuration
+
+```bash
+# View current config
+cat .envrc.local
+
+# Reconfigure
+./bootstrap.sh --config-only --image new-image:tag
+
+# Reload configuration
+direnv allow
+toolkit-restart
+```
+
+## Architecture
+
+The native toolkit uses a **symlink-based wrapper** approach:
+- Single `vicar-exec` script handles all commands
+- ~550 symlinks created dynamically
+- Fast activation (~1 second)
+- Low disk usage (~2MB)
+- Commands auto-discovered from container
+
+## Troubleshooting
+
+```bash
+# Toolkit not activating
+direnv allow
+cd .. && cd -
+
+# Container not running
+toolkit-restart
+
+# Commands not found
+echo $PATH | grep .direnv
+ls .direnv/wrappers/ | wc -l   # Should show ~550
+
+# Check wrapper implementation
+file .direnv/wrappers/gen      # Should be symlink
+readlink .direnv/wrappers/gen  # Should point to ../vicar-exec
+
+# Image issues
+docker images | grep terrain-intelligence-generator
+docker pull ghcr.io/nasa-ammos/tig/terrain-intelligence-generator:opensource
+
+# Container logs
+docker logs vicar-sidecar
+
+# Fresh start
+toolkit-stop
+rm -rf .direnv/
+direnv allow
+```

+# VICAR Native Toolkit Walkthrough - Complete Setup for TIG Demo
+
+**Goal:** Set up vicar-native-toolkit to work with the terrain-intelligence-generator:opensource image for native-like command execution in the TIG demo.
+
+**Time:** ~15-20 minutes (mostly building Docker images)
+
+---
+
+## Prerequisites
+
+Before starting, ensure you have:
+
+- ✅ **Docker Desktop** installed and running
+- ✅ **direnv** installed (`brew install direnv` on macOS, `apt install direnv` on Linux)
+- ✅ **Shell configured** with direnv hook (see below)
+- ✅ **~5GB free disk space** for Docker images
+- ✅ **XQuartz** (macOS only) for X11 forwarding
+
+### Configure direnv in Your Shell
+
+Add to your shell config file (`~/.zshrc` for zsh, `~/.bashrc` for bash):
+
+```bash
+# For bash
+eval "$(direnv hook bash)"
+
+# For zsh
+eval "$(direnv hook zsh)"
+```
+
+Then reload your shell:
+```bash
+source ~/.zshrc  # or source ~/.bashrc
+```
+
+---
+
+## Step 1: Navigate to Project
+
+```bash
+cd vicar-native-toolkit
+```
+
+**Verify location:**
+```bash
+pwd
+ls -la
+# Should show: .envrc, workspace/, DEMO.md, README.md, etc.
+```
+
+---
+
+## Step 2: Build the TIG Demo Docker Image
+
+The TIG demo uses the opensource terrain-intelligence-generator image with VICAR v5.0.
+
+```bash
+# Navigate to the docker directory
+cd ../terrain-intelligence-generator/docker
+
+# Build the opensource image
+docker build --platform linux/amd64 -t terrain-intelligence-generator:opensource .
+
+# Return to toolkit directory
+cd ../../vicar-native-toolkit
+```
+
+**Expected output:**
+```
+✅ Build successful!
+Image created: terrain-intelligence-generator:opensource
+Size: ~1.85GB
+```
+
+**Time:** ~3-5 minutes
+
+**Verify image built:**
+```bash
+docker images | grep terrain-intelligence-generator:opensource
+```
+
+Should show:
+```
+terrain-intelligence-generator:opensource    latest    <image-id>    1.85GB
+```
+
+---
+
+## Step 3: Review Configuration (Optional)
+
+The toolkit comes with a default configuration. You can create a local config:
+
+```bash
+cat > .envrc.local << 'EOF'
+# Local configuration for vicar-native-toolkit
+export CONTAINER_IMAGE="terrain-intelligence-generator:opensource"
+export MARS_CONFIG_PATH="../terrain-intelligence-generator/docker/mars_calibration_m20"
+EOF
+```
+
+**Key settings:**
+- `CONTAINER_IMAGE="terrain-intelligence-generator:opensource"` - Uses the TIG opensource image
+- `MARS_CONFIG_PATH` - Path to MARS calibration files (required for stereo processing)
+- `AUTO_DISCOVER_TOOLS=true` - Automatically finds all VICAR commands (default)
+
+**This configuration is ready to use!** No changes needed.
+
+---
+
+## Step 4: Activate the Toolkit
+
+Now activate the toolkit with direnv:
+
+```bash
+direnv allow
+```
+
+**What happens:**
+1. 📝 Loads configuration from `.envrc.local` or defaults
+2. 🔧 Detects your platform (macOS/Linux)
+3. 📦 Starts `vicar-sidecar` container with terrain-intelligence-generator image
+4. 📁 Mounts workspace directory
+5. 🔨 Discovers and generates wrappers for ~543 VICAR commands
+6. ✅ Adds wrappers to your PATH
+
+**Expected output:**
+```
+[vicar-toolkit] Activating VICAR Native Toolkit...
+[vicar-toolkit] Image: terrain-intelligence-generator:opensource
+[vicar-toolkit] Container 'vicar-sidecar' is already running
+[vicar-toolkit] Auto-discovering VICAR commands...
+[vicar-toolkit] Found 543 commands
+[vicar-toolkit] Generated 543 symlinks to vicar-exec
+[vicar-toolkit] Created 4 utility command symlinks
+[vicar-toolkit] ✅ Toolkit activated! VICAR commands now available.
+[vicar-toolkit] Try: gen, label, marsmap, toolkit-shell, toolkit-status
+
+Available commands:
+  toolkit-status    - Show configuration and container status
+  toolkit-shell     - Open interactive shell in container
+  toolkit-stop      - Stop and remove container
+  toolkit-restart   - Restart container with new configuration
+
+VICAR tools: 543 commands available
+Working directory: <current-path>/vicar-native-toolkit/workspace
+```
+
+**Time:** ~30-60 seconds
+
+---
+
+## Step 5: Verify Wrapper Generation
+
+If auto-discovery found 0 tools (due to timing), manually generate wrappers:
+
+```bash
+# Check current wrappers
+ls .direnv/wrappers/ | wc -l
+```
+
+**If less than 543 wrappers**, regenerate them:
+
+```bash
+# Clean and regenerate
+rm -rf .direnv/wrappers/*
+toolkit-restart
+cd .. && cd -
+```
+
+**Expected output:**
+```
+[vicar-toolkit] Found 543 commands
+[vicar-toolkit] Generated 543 symlinks to vicar-exec
+✅ Generated 543 wrappers in .direnv/wrappers
+```
+
+**Verify critical commands:**
+```bash
+ls .direnv/wrappers/ | grep -E "^(gen|label|hist|marscorr|marsxyz|marsmesh)$"
+```
+
+Should show all 6 commands.
+
+---
+
+## Step 6: Test Native Command Execution
+
+Test that commands work like native CLI tools:
+
+### Test 1: Basic VICAR Command
+
+```bash
+cd workspace
+
+# Generate a test image (NO Docker syntax!)
+gen out=test.vic nl=512 ns=512
+```
+
+**Expected output:**
+```
+Beginning VICAR task GEN
+GEN Version 2019-05-28
+GEN task completed
+```
+
+**✅ Success!** The `gen` command worked like a native CLI tool.
+
+### Test 2: View Histogram
+
+```bash
+hist inp=test.vic
+```
+
+**Expected output:**
+```
+Beginning VICAR task HIST
+*** HIST version 2017-08-08 ***
+
+Bin Width = 1.0
+  0    1
+  1    2  *
+  2    3  *
+  ...
+```
+
+**✅ Success!** Commands work without any Docker syntax.
+
+### Test 3: Check Container Status
+
+```bash
+toolkit-status
+```
+
+**Expected output:**
+```
+======================================================================
+VICAR Native Toolkit Status
+======================================================================
+
+Container: vicar-sidecar
+Image: terrain-intelligence-generator:opensource
+Status: Up X seconds
+
+Mounts:
+  <toolkit-path>/workspace -> /workspace
+
+Wrappers: 547 commands in .direnv/wrappers
+```
+
+**✅ Success!** Toolkit is configured and running.
+
+---
+
+## Step 7: Verify Mars Commands
+
+Test that Mars processing commands are available:
+
+```bash
+# Check if Mars commands exist
+ls .direnv/wrappers/ | grep ^mars | head -10
+```
+
+**Expected output:**
+```
+marsautoloco
+marsautotie
+marscorr
+marscor3
+marsdisparity
+marsmesh
+marsrfilt
+marsxyz
+...
+```
+
+### Test Mars Command Wrapper
+
+```bash
+# Test that marscorr wrapper exists and is executable
+which marsmesh
+file $(which marsmesh)
+```
+
+**Expected output:**
+```
+<toolkit-path>/.direnv/wrappers/marsmesh
+
+<toolkit-path>/.direnv/wrappers/marsmesh: symbolic link to ../vicar-exec
+```
+
+**✅ Success!** Mars commands have native-like wrappers.
+
+---
+
+## Step 8: Test with Real Mars Data
+
+If you have Mars stereo images or XYZ point clouds, you can copy them to the workspace:
+
+```bash
+cd workspace
+
+# Copy data files (adjust paths as needed)
+cp /path/to/your/left.VIC left_edr.vic
+cp /path/to/your/right.VIC right_edr.vic
+# or
+cp /path/to/your/pointcloud.xyz .
+
+ls -lh *.vic *.xyz
+```
+
+---
+
+## Step 9: Test Label Command
+
+```bash
+cd workspace
+
+# Generate a test image first
+gen out=test.vic nl=100 ns=100
+
+# View file info
+file test.vic
+```
+
+**Expected output:**
+```
+test.vic: VICAR image data, 8 bits  = VAX byte
+```
+
+**✅ This confirms the toolkit is working!** VICAR commands execute natively.
+
+---
+
+## Step 10: Final Verification Checklist
+
+Run through this checklist to ensure everything is ready:
+
+```bash
+# 1. Container running?
+docker ps | grep vicar-sidecar
+# ✅ Should show: vicar-sidecar   Up X minutes
+
+# 2. Wrappers generated?
+ls .direnv/wrappers/ | wc -l
+# ✅ Should show: 543+ wrappers
+
+# 3. Key commands available?

+```
+
+**All checks passed?** You're ready for the demo! 🎉
+
+---
+
+## Troubleshooting
+
+### Issue: "direnv: command not found"
+
+**Solution:** Install direnv:
+```bash
+# macOS
+brew install direnv
+
+# Linux
+sudo apt install direnv
+
+# Add to shell config
+echo 'eval "$(direnv hook zsh)"' >> ~/.zshrc
+source ~/.zshrc
+```
+
+### Issue: "Docker image not found"
+
+**Solution:** Build the opensource image:
+```bash
+cd ../terrain-intelligence-generator/docker
+docker build --platform linux/amd64 -t terrain-intelligence-generator:opensource .
+```
+
+### Issue: "Container fails to start"
+

+```bash
+direnv reload
+# Or exit and re-enter directory
+cd .. && cd -
+```
+
+### Issue: "XQuartz errors" (macOS only)
+
+**Solution:** Start XQuartz manually:
+```bash
+open -a XQuartz
+xhost +localhost
+```

+
+## Next Steps: Run Mesh Generation Demo
+
+Now that the toolkit is ready, you can run the mesh generation demo:
+
+### Run the Full Stereo Pipeline
+
+The TIG demo script will run the complete pipeline from stereo images to 3D mesh:
+
+```bash
+cd ..
+
+# Run with stereo pair (~10-15 minutes)
+./demo-mesh-native-toolkit.sh \
+  --stereo-left /path/to/left.VIC \
+  --stereo-right /path/to/right.VIC
+```
+
+### Or Run Commands Manually (Native Style)
+
+Follow the step-by-step commands in DEMO.md:
+
+```bash
+cd vicar-native-toolkit/workspace
+
+# Copy stereo pair
+cp /path/to/left.VIC left.vic
+cp /path/to/right.VIC right.vic
+
+# Run stereo correlation
+marscorr \( left.vic right.vic \) disparity_init.img template=15 search=51 quality=0.2
+marscor3 \( left.vic right.vic \) disparity.img in_disp=disparity_init.img template=11 search=31 quality=0.4
+
+# Generate XYZ point cloud
+marsxyz \( left.vic right.vic \) pointcloud.xyz disp=disparity.img
+
+# Filter rover hardware
+marsrfilt inp=pointcloud.xyz out=pointcloud_filtered.xyz
+
+# Generate mesh
+marsmesh inp=pointcloud_filtered.xyz out=terrain.obj \
+  in_skin=right.vic \
+  x_subsample=1 y_subsample=1 \
+  range_min=0.2 range_mid=100 range_max=100 \
+  lod_levels=10 max_angle=87.5 \
+  res_min=3000 res_max=500000 density=1 -adaptive \
+  maxgap=5
+```
+
+**No Docker syntax needed!** Commands work like native CLI tools.
+

+
+## Reference: Key Commands
+
+### Toolkit Management
+
+```bash
+toolkit-status     # Show configuration and container status
+toolkit-shell      # Open interactive shell in container
+toolkit-restart    # Restart container
+toolkit-stop       # Stop and remove container
+```
+
+### Container Operations
+
+```bash
+# Check container
+docker ps | grep vicar-sidecar
+
+# View logs
+docker logs vicar-sidecar
+
+# Execute command in container
+docker exec vicar-sidecar <command>
+```
+
+### Wrapper Inspection
+
+```bash
+# List all wrappers
+ls .direnv/wrappers/
+
+# View wrapper implementation
+cat .direnv/wrappers/marscorr
+
+# Check command availability
+which gen hist marscorr
+```
+

+
+## Architecture Diagram
+
+```
+User Command (e.g., "marscorr ...")
+         ↓
+Shell finds wrapper on PATH
+         ↓
+~/.direnv/wrappers/marscorr
+         ↓
+docker exec vicar-sidecar marscorr ...
+         ↓
+Long-running container (fast!)
+         ↓
+VICAR command executes
+         ↓
+Result returns to user
+```
+
+**Key Point:** User never sees Docker syntax - it all happens transparently!
+
+---
+
+## Summary
+
+You've successfully set up vicar-native-toolkit to provide **native-like command execution** for 543 VICAR commands including all Mars processing tools. The toolkit:
+
+- ✅ **Feels native** - No Docker syntax in user commands
+- ✅ **Works fast** - Long-running container (~50-100ms latency)
+- ✅ **Supports VICAR v5.0** - Open source build with Mars tools
+- ✅ **Auto-discovers commands** - 543+ wrappers generated automatically
+- ✅ **Demo-ready** - All components tested and validated
+
+**Ready to run the TIG mesh generation demo with native-like VICAR commands!** 🚀
