DESCRIPTION

15       This  program  demonstrates how to use Z-buffered polygons and floating
16       point 3D math routines. It also provides a simple way  to  compute  fps
17       (frames  per second) using a timer. After selecting a screen resolution
18       through the standard GUI dialog, the example shows two 3D cubes  rotat‐
19       ing  and  intersecting  each  other.  Rather  than having full polygons
20       incorrectly overlap other polygons due  to  per-polygon  sorting,  each
21       pixel is drawn at the correct depth.
