Detailed Description

Debug Drawer Volume Face.

Describes a face in a debug drawer shape. These faces can have any number of vertices where all vertices are considered to be coplanar. The face normal is specified explicity to avoid troubles in cases where vertices are very close together. This way an application or module wishing for some debug drawing does not have to worry about badly spaced vertices which makes debug code more simple. The face is considered to be a triangle fan type face. Hence the first vertex is the base vertex and the second vertex the first triangle base. Every next vertex defines a triangle with the first vertex, the last vertex and the newly specified vertex. The triangle fan is not closesed automatically. For filled shapes at least 3 vertices are required and for non filled shapes at least 2. If not enough vertices are specified the face not drawn.
