Detailed Description

This class represents a solid object that can be traced through collision worlds, models and shapes.

The shape of the object is defined as a convex polyhedron of arbitrary complexity. However, polyhedrons of the least possible complexity (regarding the number of vertices, planes and edges) are strongly preferable regarding performance considerations.

Moreover, the solids must be "well defined" without degeneracies. In particular, this means:

there must be no duplicate or colinear vertices,
there must be no duplicate or redundant planes, and
the solid must have a true positive volume. The only exception to these rules is a trace solid with exactly one vertex, no planes and no edges. Such trace solids are treated equivalently to point traces, so that special-case optimized code is employed.
