Welcome to the VPython Forum. You need to be signed in to be able to post messages.

This forum serves users of VPython, an easy to use 3D programming environment for Python: see vpython.org.

If you would like others to see a program you've written, post a note that starts with "VPDEMO:". Then users can "Search for topics" with the keyword VPDEMO to find such programs.

User discussions used to be handled by a mailing list. Here are the archives.
