#IPAS Routines
Collision detection would be special-cased, so that the axp knows how the
objects are built. You'd probably be limited to primitives and simple
convex objects. We do some of this with rain.axp… when the raindrops
"collide" with the floor plane, they splat out into puddle shapes. And
likewise with explode and disintegrate… but very special-cased, dealing
with the ground plane only.
