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.
