Re: [Visualpython-users] CPU usage

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

What's happening is that for simplicity and robustness VPython renders 
the scene about 25 frames per second, each time starting from a blank 
slate. No attempt is made to determine whether any change has been made 
to the scene. Obviously in principle the architecture could be changed 
to make it unnecessary to do more than check for interactions, but 
that's not the current architecture.
