[ODE] Particles

[Jon Watte]

What is a particle? If it's for a particle system, then you probably 
want to have some extent to the particles. At that point, a sphere 
with an appropriately small radius is the best way to do it.

Actually, the difference in math between particle and sphere is so 
small that using spheres with millimeter radius should be fine, even 
if you want "point" particles. The only caveat would be that a small 
object can travel THROUGH certain surfaces (most notably trimeshes) 
through tunneling, so you might want to use rays or ccylinders based 
on the particle speed.

I don't doubt that a cool wrapper could be written on top of ODE for 
a particle system with ccylinders for each sphere-sized particle, but 
I belive that such code could (and should) sit on top of ODE, rather 
than be (or have to be) integrated.

Cheers,

Quick question. I might have missed something. Is there an easy way to 
do particles integrated into ODE, what I'm looking for is a particle 
geom. Is there one or do I need something else?

thanks -Will
