Yes I am. That's the point. In my POV script I have access to the surfaces
of the object through the trace function. In an external program I wouldn't
have access to the surfaces.

Err, the particle locations etc. are directly dependent on the collisions.
The collision detection is an integrated part of the system. It's not
possible to calculate all the physics first and then the collisions later.

I don't know how you're going to implement it, but I expect you don't have
direct support for all POV-Ray objects for the collision detection?

I'm certainly looking forward to that!
