Let say we have a geo-map and want to identify the occupation of a house, which is a square. We may want to draw a rectangle and calculate the occupation area outside the rectangle..
If we want to keep a point-based, then we may want to turn the area into a series of points and merge all the Voronoi into a single one and subtract the area..
