#include <UT_Tetrahedralize.h>
The UT_TetTetrahedron class is the primary structure in the tetrahedralization process. It holds pointers to its four vertex objects, as well as to any adjacent tetrahedra. The convention is that a particular adjacent tetrahedra is stored with the same index as the face to which it is adjacent and the vertex from which it is opposite. In other words, adjacent(i) is adjacent to face(i), which is opposite vertex(i).
Several of the member functions are related to maintaining the adjacency relationships during the tetrahedralization process. They are called only from the various flip?? functions.
This class also holds a visited flag that is used to stop iterating during walks through adjacent tetrahedra in the walk function and the tetrahedralization function. This is faster than using something like hboost::unordered_set to keep track of visited tetrahedra at the expense of a small amount of memory.
