GMAN
A RenderMan-compatible renderer, revived in 2026
GMAN is a RenderMan-compatible renderer begun in 1999 and revived in 2026. Give it a RIB scene and it renders an image. Version 0.6.0 marks the revival.
The z-buffer renderer supports all seven RenderMan quadrics, convex polygons, matte/plastic/metal surface shaders, ambient/distant/point lights and TIFF, PNG, JPEG and PNM output. It builds on macOS and Linux with C++17 and CMake.

GMAN implements part of the RenderMan interface. Texturing, antialiasing, motion blur and shading-language compilation remain unfinished. See the GitHub README and release notes for current capabilities. SourceForge preserves the project's early history and releases.
