Converts a 2D polygon into a 3D polygon. The 2D points will lie on the x-y plane (e.g. (x,y,0)) and are
converted to 3D using polyToWorld.

@param polygon2D (Input) polygon
@param polyToWorld (Output) transform from 2D to 3D coordinate system.
@param output
Converts a 2D polygon into a 3D polygon . The 2D points will lie on the x - y plane ( e . g . ( x y 0 )) and are converted to 3D using polyToWorld .
