How the clipping/culling is done in Performer? Does Performer rely on the
hardware
and compute if each point is in 3D is in the viewing frustrum at each frame?
I was
wondering if may be the scene graph was used in a way that would faster the
process
on the assumption that the view frustrum for the current frame is in a 3D
attitude
close to the one of the previous frame. I beleive that this is generally the
case in
most simulations. Are the octrees what I am just describing here?
Thanks
Yohan
