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. SEE ALSO
create_sub_zbuffer(3alleg4), set_zbuffer(3alleg4), clear_zbuffer(3alleg4), destroy_zbuffer(3alleg4), exzbuf(3alleg4) Allegro version 4.4.2 create_zbuffer(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
