.SH NAME
clear_zbuffer \- Writes a depth value into the given Z-buffer. Allegro game programming library.\&
.SH SYNOPSIS
.B #include <allegro.h>

.sp
.B void clear_zbuffer(ZBUFFER *zbuf, float z);
.SH 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).
