Hi there,

I need to do some accurate collision detection (i.e., polygon to
polygon), luckily with small Performer databases. It seems to me that
the pfSeg* functions can only be used to intersect lines with Performer
geometry, and the sphere/cylinder/box/half-space volume-volume
intersection functions are not sensitive enough for my purposes.

Has anyone implemented polygon-polygon collision detection in Performer,
or know of a neat workaround that'll allow me to exploit the features
provided by pfSeg* etc.?

Of course, I should add, my DBs contain various DCSs which complicate the
issue, and my ultimate aim is to do proximity checking, not just collision
detection.

I hope someone can provide some suggestions!

roy
