one part i really dont like about aproximating holes with a trimesh is
the fact, that there might odd things happening (speaking out of pure
inexperience) - depending on how much tris you are acutally using.
for a pool simulation i would consider experimenting in the area of
using a cylinder where the hole is (this way you can generate different
table sizes (7", 8", 9", 12") and also ball sizes programmatically
(regular, snooker) - and snooker tables have round edges near the
when colliding and the sphere with the cylinder and the depth of the
contact is bigger than the radius the ball falls in. does this sound
reasonable to the ode gurus here?
of course this way you would not be able to account for effects like
balls jumping out of pockets again because the ball would not really
have a hole to fall in - just a "place" on the plane where it happens.
