VPython
by David Scherer, et al.
VPython is a module for Python programmers that greatly
simplifies 3D graphics programming.
Why Highlighted: VPython is a good example of a
specific, open source solution to a problem, in this case a lack of
good 3D programming support in Python. Check the sample program
page (linked from the project’s main page) to see how much it can
simplify 3D programming and modeling.
