## What it is
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

## Facets
- artifact type: library
- maturity: maintenance
- function: graphics, image-processing, simulation
- domain: graphics, computer-vision, machine-learning, developer-tools
- platform: python, windows, cross-platform
- tags: opengl, gltf, pbr, offscreen-rendering, 3d-visualization, egl, osmesa, trimesh, linux, macos
