clear_zbuffer(3)		Allegro	manual		      clear_zbuffer(3)

NAME
       clear_zbuffer  -	 Writes	a depth	value into the given Z-buffer. Allegro
       game programming	library.

SYNOPSIS
       #include	<allegro.h>

       void clear_zbuffer(ZBUFFER *zbuf, float z);

DESCRIPTION
       Writes z	into the given Z-buffer	(0  means  far	away).	This  function
       should  be used to initialize the Z-buffer before each frame. Actually,
       low-level routines compare depth	of the current pixel with 1/z: for ex-
       ample, if you want to clip polygons farther  than  10,  you  must  call
       clear_zbuffer(zbuf, 0.1).

SEE ALSO
       create_zbuffer(3), set_zbuffer(3), destroy_zbuffer(3), exzbuf(3)

Allegro				 version 4.4.3		      clear_zbuffer(3)
