7       game programming library.

SYNOPSIS

10       #include <allegro.h>

12
13       int clip3d(int type, fixed  min_z,  fixed  max_z,  int  vc,  const  V3D
14       *vtx[], V3D *vout[], V3D *vtmp[], int out[]);
15

DESCRIPTION

17       Fixed  point  version  of clip3d_f(). This function should be used with
18       caution, due to the limited precision of  fixed  point  arithmetic  and
19       high  chance  of rounding errors: the floating point code is better for
20       most situations.
21

RETURN VALUE

23       Returns the number of vertices after clipping is done.
