**NAME**

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

**SYNOPSIS**

#include<allegro.h>intclip3d(inttype,fixedmin_z,fixedmax_z,intvc,constV3D*vtx[],V3D*vout[],V3D*vtmp[],intout[]);

**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.
