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.
