static const char test4[8] = {7, 7, 7, 7, -7, -7, -7, -7}

test table for case 4 Interior to test When the test on the interior is negative : 2 first triangles When the test on the interior is positive : 6 last triangles

For each of the case above, the specific triangulation of the edge intersection points is given. When a case is ambiguous, there is an auxiliary table that contains the face number to test and the tiling table contains the specific triangulations depending on the results A minus sign means to invert the result of the test.
