Splits a Polygon by this plane if needed. After that it puts the polygons or the polygon fragments in the appropriate lists (

front

,

back

). Coplanar polygons go into either

coplanarFront

,

coplanarBack

depending on their orientation with respect to this plane. Polygons in front or back of this plane go into either

front

or

back

.

Parameters

polygon	polygon to split
coplanarFront	"coplanar front" polygons
coplanarBack	"coplanar back" polygons
front	front polygons
back	back polgons
