SyntaxilitY 3D GLTF Model Viewer is a lightweight, browser-based viewer for 3D models saved in the glTF/GLB format. It provides a fast, easy-to-use interface for previewing, inspecting, and interacting with models directly in the browser — no heavy tooling required. The viewer focuses on faithful rendering of PBR materials, animation playback, and real-time inspection to help artists, developers, and QA teams quickly validate and demonstrate 3D assets.
Key goals:
- Accurate visual rendering of glTF assets.
- Simple, intuitive controls for inspecting models and animations.
- Fast load times and responsive UI for both desktop and mobile.
Features:
- glTF / GLB loading (local file drop and remote URLs)
- PBR material support (baseColor, metallic/roughness, normal, occlusion, emissive)
- Animation playback controls (play, pause, scrub, loop, speed)
- Camera controls (orbit, pan, zoom, reset)
- Scene graph / model hierarchy inspector (view nodes, meshes, materials)
- Lighting presets and HDRI environment support for realistic preview
- Toggleable rendering options (wireframe, bounding box, skeleton, vertex normals)
- Model statistics (triangles, vertices, textures, file size)
- Screenshot export (PNG)
- Drag-and-drop support for rapid previews
- Responsive UI with keyboard shortcuts for power users
- Extensible plugin-friendly architecture (hooks for custom UI or rendering extensions)
Why develop this:
- Faster iteration: Artists and developers need a quick way to validate 3D assets without launching a full DCC app. A compact web viewer reduces iteration time and helps catch visual issues earlier.
- Reliable previews: glTF is the modern, interoperable 3D interchange format. A dedicated viewer ensures PBR materials and animation behave consistently across platforms.
- Debugging and QA: Inspecting scene graph, materials, and animation states in-browser makes it easier to find export/import problems and rendering mismatches.
- Sharing and demos: A browser viewer lets teams and stakeholders preview assets and prototypes instantly via a URL or shared file — no installs required.
- Extensibility: An open-source viewer can be integrated into pipelines, asset stores, documentation sites, and editor tooling, and extended to fit specific production needs.
- Learning resource: Provides a practical, hands-on environment for developers learning glTF, PBR rendering, and real-time graphics concepts.
