C# Class idTech4.Collision.idCollisionModelManager

Trace model vs. polygonal model collision detection.

Short translations are the least expensive. Retrieving contact points is about as cheap as a short translation. Position tests are more expensive and rotations are most expensive.

There is no position test at the start of a translation or rotation. In other words if a translation with start != end or a rotation with angle != 0 starts in solid, this goes unnoticed and the collision result is undefined.

A translation with start == end or a rotation with angle == 0 performs a position test and fills in the trace_t structure accordingly.
