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.
