Phcutdata(MS of vetices VL, MS of face indices FL, plane data PlaneD)

make PD3d of polyhedron and cutting plane.
多面体を平面で切ったときの多面体と切断面の3d リストを作成
¦ Form of PlaneD
a¤x+b¤y+c¤z-d , a¤x+b¤y+c¤z=d
[a, b, c, d]
Mix(a, b, c, P) Plane on which P lies.
¦ Cutting plane is the last opponent of MS
Ex) VL=Mix([0, 0, 0], [1, 0, 0], [0, 1, 0], [0, 0, 1]);
FL=Mix([1, 2, 3], [1, 2, 4], [1, 3, 4], [2, 3, 4]);
PL=Phcutdata(VL, FL, ’[1, 1, 1, 3)’);
