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 cau- tion, due to the limited precision of fixed point arithmetic and high chance of rounding errors: the floating point code is better for most situ- ations. RETURN VALUE Returns the number of vertices after clipping is done. SEE ALSO polygon3d(3), clip3d_f(3) Allegro version 4.4.3 clip3d(3)
