RE: [Visualpython-users] nested frames, cpu times

[Kuzminski, S. R <SKu...@fa...>]

Hmm, Stonehenge takes ~20% of the cpu on my XP laptop. The date at the
top of __init__.py is "Visual-2003-10-05".  Perhaps I will try a more
recent release.

If that renderer thread doesn't sleep at some point in its loop, it will
consume a lot of CPU just looping, but usually that behavior is to use
100% of the CPU.

thanks,
S

That's odd. I ran lathe.py from the VPython demo suite and observed CPU=20
usage, which was less than 1% on a 2.6 GHz Windows XP machine. Note that

lathe.py makes a display and then ends. Even running stonehenge.py,=20
which has a continuous animation and looks for user mouse inputs, runs=20
at less that 1%. There is a rendering thread which many times per second

renders the scene, and it isn't "smart" -- it doesn't do any=20
optimization but every time clears some memory to black and repaints the

whole scene. But this is a fast process.

Yes, you can nest frames within frames.
