Pyrender is a pure Python, glTF 2.0-compliant OpenGL renderer for physically-based rendering and visualization of 3D scenes. It includes an interactive scene viewer and a headless offscreen renderer with OSMesa and EGL backends, making it well suited for machine learning pipelines.

Use cases

• render 3D meshes offscreen for machine learning datasets
• view and inspect glTF 2.0 scenes interactively
• generate depth and color images from 3D scenes on headless servers
• convert and render OBJ, STL, PLY, and GLB files via trimesh
• visualize 3D reconstructions with physically-based materials

When to choose

• you need lightweight, pip-installable 3D rendering in Python
• you need GPU-accelerated offscreen rendering on headless servers with EGL or OSMesa
• you want glTF 2.0-compliant physically-based rendering with shadows and transparency
• you already use trimesh and want easy mesh rendering

When to avoid

• you need a full game engine or real-time high-performance rendering
• you need Vulkan, DirectX, or ray-tracing capabilities
• you need an actively developed project with frequent updates
• you need rendering outside Python
