# Treat a cube as a bitmap, and create the index into this array in order of
# ZYX (note Z is the most significant digit).
# The resulting object is an array of triangles, where each triangle is 6
# indices. Each consecutive pair of indices within this triangle represents an
# edge spanning two corners (identified by the indices).
#
# The corners of a cube are indexed as follows
#
#    (0, 0, 0), (1, 0, 0), (0, 1, 0), (1, 1, 0),
#    (0, 0, 1), (1, 0, 1), (0, 1, 1), (1, 1, 1)
#
# Here is a visualization of the cube indices:
