exzbuf(3)                       Allegro manual                       exzbuf(3)

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.
