NAME

       create_zbuffer - Creates a Z-buffer for a bitmap. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       ZBUFFER *create_zbuffer(BITMAP *bmp);

DESCRIPTION

       Creates	a  Z-buffer using the size of the BITMAP you are planning to draw on. Several Z-buffers can be defined but only one can be used at
       the same time, so you must call set_zbuffer() to make this Z-buffer active.

RETURN VALUE

       Returns the pointer to the ZBUFFER or NULL if there was an error. Remember to destroy the ZBUFFER once you are done with it, to avoid  hav-
       ing memory leaks.

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.
