NAME

       exzbuf - Z-buffered polygons demo. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       Example exzbuf

DESCRIPTION

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