Function GeometrySingleton.intersectPolygons2d
Intersects polygon_a
with polygon_b
and returns an array of intersected polygons. This performs constant OPERATION_INTERSECTION
between polygons. In other words, returns common area shared by polygons. Returns an empty array if no intersection occurs.
The operation may result in an outer polygon (boundary) and inner polygon (hole) produced which could be distinguished by calling isPolygonClockwise
.
