Detailed Description

the convex hull of the orthogonal projection of the vtkPoints in the 3 coordinate directions

a subclass of vtkPoints, it maintains the counter clockwise convex hull of the points (projected orthogonally in the three coordinate directions) and has a method to test for intersection of that hull with an axis aligned rectangle. This is used for intersection tests of 3D volumes.
