clip3d - Man Page

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


#include <allegro.h>

int clip3d(int type, fixed min_z, fixed max_z, int vc, const V3D *vtx[], V3D *vout[], V3D *vtmp[], int out[]);


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.
