triangleTable2
protected static final byte[][] triangleTable2
The new triangle table developed specifically for Jmol. The fourth number in each ABC set is three bits, b3b2b1, where b1 = 1 for AB, b2 = 1 for BC, b3 = 1 for CA, and mark lines to be drawn for mesh So, for example: 1, 8, 3, 6 6 is 110 in binary, so b3 = 1, b2 = 1, b1 = 0; b1 refers to the 18 edge, b2 refers to the 83 edge, and b3 refers to the 31 edge. The 31 and 83, but not 18 edges should be drawn for a mesh. On the cube above, you can see that the 18 edges is in the interior of the cube. That's why we don't render it with a mesh.
