Well it does have sphere collision, but not custom shapes. A sphere collision isn't really testing on each and every triangle of a volume.
In some 3D physics engine you have built in "shapes" for collsions such as Sphere, Cube, Cylinder, Rectangle. Basic volumes like that can be used to create collision testing without needing to check each and every triangle. Once you get to face-level collision I believe that's called rigid body collison. You wouldn't really need that to create the effect seen in the video of a 300 barrels, if you could just used a volume to check, like a Cylinder Volume instead of check every face of your 3d model of a barrel. So, A Cylinder Collison doesn't need to check every face, if the formula to check certain volumes was used. A cylinder volume would take more to calculate than just a simple Sphere (which is just distance). Anyone want to correct me or add any info on this for BlueBomber357 feel free! -Pete 2008/8/25 Bluebomber357 <[EMAIL PROTECTED]> > > I am still confused, does rigid body collisions simply mean when two > rigid bodies collide?
