Example: Collision Detection with Volume/Surface Tolerances

Run Collision Detection with the Tolerance settings shown here.

The following two cubes are one cubic meter each. They collide slightly; the overlapping volume is very slight (it doesn’t exceed Volume Tolerance), but the overlapping surface is considerable (it exceeds Surface Tolerance). As a result: Collision Detection counts these two elements as colliding.
