SYNOPSIS

10       #include <allegro.h>

12
13       ZBUFFER *create_zbuffer(BITMAP *bmp);
14

DESCRIPTION

16       Creates a Z-buffer using the size of the BITMAP  you  are  planning  to
17       draw  on.  Several Z-buffers can be defined but only one can be used at
18       the same time, so you must call set_zbuffer()  to  make  this  Z-buffer
19       active.
20

RETURN VALUE

22       Returns  the  pointer  to  the  ZBUFFER  or NULL if there was an error.
23       Remember to destroy the ZBUFFER once you are done  with  it,  to  avoid
24       having memory leaks.
