• PolygonIntersections is an option for Graphics3D which specifies whether intersecting polygons should be left unchanged.
• With the default setting PolygonIntersections -> True
objects are returned unchanged whether or not they contain intersecting polygons.
• With the setting PolygonIntersections -> False
objects are modified by breaking polygons into smaller pieces which do not intersect each other.
• PolygonIntersections -> False is useful in creating graphics objects which can be sent to certain external three-dimensional rendering programs.
• New in Version 2.
