05-18-04, 06:34 PM Can anyone tell me how you would go about
calculating spherical collision patterns? I've been playing a 3d
pool game that is very realistic and I am amazed at how life-
like the ball collisions are. Any info on this subject would be
greatly appreciated. 05-18-04, 07:12 PM Everything except the
collision-detection should be pretty basic. I think that if ball
A hits ball B at point P on the surface of A, the direction of
change in momentum on B will be normal to P on A. The magnitude
of change will be proportional to the momentum of A times cos(v)
where v is the angle between the momentum-vector of A and the
normal through P also going through the center of A. I'm not
sure it works like this tho, but it seems reasonable. 05-19-04,
01:52 AM Im no mathematician although the subject fascinates me
so you may have to help me out here a little if thats cool. I
think I understand what you are saying and it seems reasonable,
however it must get massively complicated when 'spin' is applied
to ball 'A'.
