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.

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.
Reimplemented from vtkPoints.

vtkPointsProjectedHull* vtkPointsProjectedHull::New ( ) [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.
Reimplemented from vtkPoints.
