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.
