I was wondering if not sending away a projectile,
like a cube which is 0.000001 (just for example) in size,
is faster than ray picking.
For me picking is eating time and I want to fix this (big) problem.
If we finally could make a good collision detector, I think sending away that cube in the speed of light hehe 
would be faster.
Will, you know more than I do in this case so please reply ;).
