3D Programming for Ordinary Mortals


VPython is the Python programming language plus a 3D graphics module called "visual" originated by David Scherer in 2000. VPython makes it easy to create navigable 3D displays and animations, even for those with limited programming experience. Because it is based on Python, it also has much to offer for experienced programmers and researchers.

For a quick introduction, see these YouTube videos:

3D Objects

Variable Assignment

Beginning Loops

Loops and Animation

Scale Factors

Debugging Syntax Errors
