[Visualpython-users] 4.beta22

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

4.beta22 now available for Windows and Linux at sourceforge. Fixed a bug 
which made rendering of spheres very slow. When doing some experiments 
on adjusting the level of detail for spheres, Arthur Siegel in December 
2006 commented out the statement that used a cached description of a 
sphere. The effect was to recompute a 3D model of every sphere in every 
render cycle.

There are still some issues with slow rendering in the beta version, but 
this was certainly the most serious bug. The recently contributed 
program vspace.py now runs on the beta version, though not as well as on 
the production version of VPython.
