17sep10 So, even if Vpython is based on OpenGL, it looks like Scherer wrapped the relevant OpenGL up in visual.py. On Windows the current Vpython requires Python2.5 which it downloads and puts into C:\ . But even after superinstalling the visual stuff in it, there is no OpenGL support. On the other hand, Aszgard2010 (earlier?), the movpy not only has OpenGL support but also runs with Psyco importation in place, as in Stan's suite. 12jan10 Scherer's visual appears to work in immediate mode after a >>> from visual import * But, unless we have some sample code from VPython and its fixation on Idle, this isn't going to work. I tried the box command. It really did open a window and showed a view of it. But, of course, it won't rotate. Now called "visualpy" contains wisdom in this direction. Used to be "docs". One can, laboriously, accumulate commands for visual, and use the gingerly.
