Are there any good particle includes/macros besides the ones by
Colefax?  I'm kind of hoping there's one out there that can handle
collision detection against any object, be it using trace() or
whatever.  What I need is something very basic - particles emitting from
an area and falling straight down like rain.  While it would be cool for
them to bounce off objects, I could just have them die on contact.

Anyway, the particles themselves are easy enough to make, but how can I
tell if one has hit an object between frames?  Better yet, maybe someone
has already done it.

Help!!! ;)

Check out the unofficial version of POV called MegaPOVplus, where Chris Huff has
imlemented a particle system object. It can do collision detection with
arbitrary objects, and has other neat features. The URL is

One thing you should be warned about: the current version of MP+ is 
based on an older version of MegaPOV(0.5a). Also, it might be wise to 
avoid using the ipf_profile feature of the particle_system object, I 
plan on doing this kind of thing in a more versatile way in a future 
version.
