From 1e0102fe03a66fef36915f78cb509f2e9be2726f Mon Sep 17 00:00:00 2001 From: Claude Date: Thu, 6 Nov 2025 17:42:54 +0000 Subject: [PATCH 1/5] Add batch processing support to MeshDenoiser Implements batch processing feature that allows processing multiple mesh files at once by providing directories instead of individual files. Key features: - Automatic discovery of all supported mesh files in input directory - Creates output directory if it doesn't exist - Preserves original filenames in output - Progress tracking with file count (e.g., [1/5] Processing: file.obj) - Error handling - continues processing if one file fails - Summary report showing success/failure counts Usage: MeshDenoiser options.txt input_dir/ output_dir/ Changes: - Added filesystem support with C++17 std::filesystem and fallbacks - Refactored single-file processing into reusable function - Added directory detection and file listing utilities - Updated CMakeLists.txt to use C++17 standard - Updated README with batch processing documentation and examples The implementation is cross-platform compatible with proper fallbacks for systems without C++17 filesystem support (Windows, Linux, macOS). --- CMakeLists.txt | 5 + README.md | 54 +++- overrides/MeshSDFilter/MeshDenoiser.cpp | 361 +++++++++++++++++++++--- 3 files changed, 377 insertions(+), 43 deletions(-) diff --git a/CMakeLists.txt b/CMakeLists.txt index b21a7d3..9605d17 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -1,6 +1,11 @@ cmake_minimum_required(VERSION 3.18) project(meshsdfilter-builder LANGUAGES CXX) +# Set C++17 standard for filesystem support +set(CMAKE_CXX_STANDARD 17) +set(CMAKE_CXX_STANDARD_REQUIRED OFF) +set(CMAKE_CXX_EXTENSIONS OFF) + include(FetchContent) list(APPEND CMAKE_MODULE_PATH "${CMAKE_CURRENT_SOURCE_DIR}/cmake") diff --git a/README.md b/README.md index 2c05291..b7a193f 100644 --- a/README.md +++ b/README.md @@ -19,7 +19,7 @@ MeshSDFilter requires: OpenMP is an open standard for shared-memory parallelism; compilers that support it (e.g. GCC, Clang with `libomp`, MSVC) let MeshSDFilter run heavy loops across multiple CPU cores. -> Note: MeshSDFilter expects Eigen to be discoverable via `find_package(Eigen3)`.

Features: - ProgressIndicator class with terminal animation support - Spinner animation (|/-\) with real-time elapsed time display - Detects TTY to enable/disable animation (falls back to dots in pipes) - Shows mesh statistics (vertex/face counts) after loading - Displays timing for each processing stage - Cross-platform support (Windows/Unix) Single file mode: - Loading mesh: shows spinner + mesh stats on completion - Denoising mesh: shows spinner with elapsed time - Saving mesh: shows quick spinner - Total elapsed time displayed at end Batch mode enhancements: - Individual file progress with indented output - Total batch processing time in summary - Average time per file calculation - Improved readability with cleaner output format Example output: Loading mesh | (2s) Loaded mesh (12543 vertices, 25086 faces) (0.12s) Complete (2.45s) Updated README with new progress indicator documentation and improved output examples showing the enhanced feedback. --- README.md | 33 ++-- overrides/MeshSDFilter/MeshDenoiser.cpp | 200 ++++++++++++++++++++---- 2 files changed, 193 insertions(+), 40 deletions(-) diff --git a/README.md b/README.md index b7a193f..76190ca 100644 --- a/README.md +++ b/README.md @@ -108,14 +108,14 @@ Batch processing features: - **Automatically discovers** all supported mesh files in the input directory - **Preserves filenames** - each output file has the same name as its input - **Creates output directory** if it doesn't exist -- **Progress tracking** - shows which file is being processed and overall statistics +- **Progress indicators** - animated spinner showing loading, denoising, and saving progress +- **Real-time feedback** - displays mesh statistics (vertices, faces) and elapsed time - **Error handling** - continues processing remaining files if one fails -- **Summary report** - displays success/failure counts at the end +- **Summary report** - displays success/failure counts and average processing time Example: ```bash # Process a directory of scanned meshes -mkdir cleaned_meshes MeshDenoiser MeshDenoiserDefaults.txt scanned_meshes/ cleaned_meshes/ ``` @@ -125,23 +125,34 @@ Batch processing mode Input directory: scanned_meshes/ Output directory: cleaned_meshes/ -Found 5 mesh file(s) to process +Found 3 mesh file(s) to process -[1/5] Processing: scan001.obj - Success! +[1/3] scan001.obj + Loaded mesh (12543 vertices, 25086 faces) (0.12s) + Complete (2.45s) -[2/5] Processing: scan002.ply - Success! +[2/3] scan002.ply + Loaded mesh (8421 vertices, 16842 faces) (0.08s) + Complete (1.89s) -... +[3/3] model.gltf + Loaded mesh (15632 vertices, 31264 faces) (0.15s) + Complete (3.12s) ================================== Batch processing complete - Successful: 5 + Successful: 3 Failed: 0 - Total: 5 + Total: 3 + Time: 7.56s (avg: 2.52s per file) ``` +The progress indicator shows: +- **Loading phase**: Spinner animation with vertex/face count on completion +- **Denoising phase**: Spinner animation with elapsed time +- **Saving phase**: Quick spinner during file write +- Terminal animation works in interactive shells; falls back to simple dots in pipes/logs + ### Supported Formats - A detail-preserving MeshDenoiser preset is in `MeshDenoiserDefaults.txt` (outer iterations 1, lambda 0.15, eta 2.2, mu 0.2, nu 0.25).
