I have just released the first beta version of the Python Computer Graphics Kit, a collection of Python modules that contain the basic types and functions required for creating 3D computer graphics images. http://cgkit.sourceforge.net The kit includes several new types such as vectors, matrices and quaternions. It contains a binding for Pixar's RenderMan interface which is a renderer independent API to communicate 3D data to renderers which will finally produce a 2D image. There are already several RenderMan compliant renderers freely available (they are not part of the kit). The kit also includes some of the functionality from the RenderMan Shading Language which enables you to create procedural models or textures from within Python. Even though the kit focuses on RenderMan, the new types or the Shading Language functionality can also be used for other rendering mechanism such as OpenGL or other renderers such as POV-Ray. The kit should run on any platform where Python (and a C/C++ compiler) is available. Windows users can download a binary version for Python 2.1 or Python2.2.
