exzbuf(3alleg4) Allegro manual exzbuf(3alleg4) 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. SEE ALSO
