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 example, if you want to clip polygons farther than 10, you
       must call clear_zbuffer(zbuf, 0.1).
