F3D is a fast, minimalist open-source 3D viewer desktop application supporting many formats (glTF, USD, STL, STEP, OBJ, FBX, Alembic) with real-time PBR, raytracing, volume rendering, and animation playback. It is fully scriptable from the command line and ships with libf3d, a C++17 rendering library with Python, Java, and JavaScript bindings.
Use cases
- view stl and step 3d models quickly
- preview gltf/glb assets with physically based rendering
- render 3d files to png from the command line
- inspect cad engineering models
- visualize volumetric scientific datasets
- generate file manager thumbnails for 3d formats
- embed 3d mesh rendering in a python or C++ application
- play gltf animations with skinning
When to choose
- you need a lightweight, scriptable viewer for many 3D formats without a heavy DCC tool
- you want headless/offscreen rendering of meshes to images in CI or pipelines
- you need a simple library API to render meshes in C++, Python, or Java
- you want PBR, raytracing, or volume rendering for quick previews
When to avoid
- you need full 3D modeling, sculpting, or scene editing (use Blender)
- you need a game engine or real-time application framework
- you need collaborative 3D review or asset management workflows
