Hi Fang, mpClipPolyPolygon is the current clipping geometry. It is used for clipping. The result of
rPolyPoly.GetIntersection( *mpClipPolyPolygon, aPolyPoly ); is a geometry that only contains the parts of aPolyPoly that are inside of mpClipPolyPolygon. rPolyPoly is the unclipped geometry and aPolyPoly is the clipped geometry.
