* \brief case mapping
* For each of the possible vertex states listed in this table there is a
* specific triangulation of the edge intersection points. The table lists
* all of them in the form of 0-5 edge triples with the list terminated by
* the invalid value -1. For example: case[3] list the 2 triangles
* formed when cube[0] and cube[1] are inside of the surface, but the rest of
* the cube is not.
