create_zbuffer(3) Allegro manual create_zbuffer(3)NAMEcreate_zbuffer - Creates a Z-buffer for a bitmap. Allegro game programā
ming 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
having memory leaks.
