clip3d(3)			Allegro manual			     clip3d(3)

NAME
       clip3d - Clips the polygon given in vtx using fixed point math. Allegro
       game programming library.

SYNOPSIS
       #include <allegro.h>

       int clip3d(int type, fixed  min_z,  fixed  max_z,  int  vc,  const  V3D
       *vtx[], V3D *vout[], V3D *vtmp[], int out[]);

DESCRIPTION
       Fixed  point  version  of clip3d_f(). This function should be used with
       caution, due to the limited precision of	 fixed	point  arithmetic  and
       high  chance  of rounding errors: the floating point code is better for
       most situations.

RETURN VALUE
       Returns the number of vertices after clipping is done.

SEE ALSO
