Re: [Visualpython-users] Problems with VPythonbeta20

[Bruce S. <Bru...@nc...>]

Additional comments: I took my own advice and saw what happens if I turn 
off graphics acceleration (screen settings > advanced > troubleshoot). 
Running glinfo.py from the VPython examples one sees that the Microsoft 
software OpenGL renderer is invoked. When I try to create a sphere, I 
see a window frame flash briefly and disappear. Only if I increase the 
hardware acceleration to the point where glinfo.py shows the graphics 
card's OpenGL renderer active can I create a window and see a sphere.

I thought it was supposed to be the case that the software OpenGL engine 
would produce images, just more slowly than a graphics card would do. 
Guess that's not the case, or lease not the case with the current 
beta-version code in VPython.
