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.
