 The cube index determines the sequence of edges to split. The index ranges from 0 to 255, representing all possible combinations of the 8 corners of the cube being greater or less than the isosurface threshold. For example, 10000110 (8-bit binary for decimal index 134) has corners 7, 2, and 3 greater than the threshold. After determining the cube's index value, the triangulation order is looked up in a table.
