Pyrender

Pyrender is a pure Python library (compatible with Python 2.7, 3.4, 3.5, 3.6, though recent Python versions have known issues) for physically-based rendering and visualization. It adheres to the glTF 2.0 specification and provides both an interactive scene viewer and an offscreen renderer capable of GPU-accelerated rendering on headless servers, making it well-suited for machine learning applications. It is lightweight, easy to install, and designed for simplicity of use. The current version is 0.1.45, with development continuing on GitHub.
