clip3d(3alleg4)                  Allegro manual                  clip3d(3alleg4)



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.
