Re: [Visualpython-users] VPython render efficiency

Thanks, Art,

got it! 
So we just need to wait;)

By the way, I would like to remind the authors, the simplicity of vpython
is vital! Do not lose it when you are trying to provide more!
(you are working on adding lighting, texture, transparency...)
It looks like a real 3D game engine more and more. Be careful!

Keep VPython simple to use and fast enough, please!

VPython adjusts level of detail for primitives like spheres and cylinders on
the fly based on distance from the camera.

But I agree that the general level of detail should be under user control.

I had pointed out to Bruce that the infrastructure to allow adjustment of
level of detail from the default (it would be on a scene by scene basis,not
a primitive by primitive bases) is already in the code, and that exposing it
to Python was trivial, and provided the code.

I've lost track of whether it was checked into CVS.

Bruce?
