"Soya 3D is a Python-based high-level 3D engine." (8 words)
Soya 3D has some great features, such as multi-platform compatibility with other OS like MacOSX and Windows. The inclusion of objects like cameras, lights, and worlds is great for those looking for a comprehensive 3D engine. Additionally, particle systems, full-screen options and tutorials are included. Other features available are trees, ray picking, landscapes, 3D character animation (using Cal3D), export scripts for software like Blender and Maya, event management (mouse and keyboard), cell shading, shadows and environment mapping.
Version 0.6.1 and below were C and Python-based, while version 0.7 and higher are written in Pyrex and Python. However, keep in mind that there are some requirements needed to run Soya 3D. A few you should know are Python 2.2 or higher, the Python devel files, Pyrex, PIL (Python imaging library), OpenGL, SDL, Cal3D, libFreeType2 and FreeFont.
