Detailed Description
Uses graphics hardware to picks props behind a selection rectangle on a viewport.
Like vtkAreaPicker, this class picks all props within a selection area on the screen. The difference is in implementation. This class uses graphics hardware to perform the test where the other uses software bounding box/frustum intersection testing.
This picker is more conservative than vtkAreaPicker. It will reject some objects that pass the bounding box test of vtkAreaPicker. This will happen, for instance, when picking through a corner of the bounding box when the data set does not have any visible geometry in that corner.

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

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.

Perform pick operation in volume behind the given screen coordinates. Props intersecting the selection frustum will be accessible via GetProp3D. GetPlanes returns a vtkImplicitFunciton suitable for vtkExtractGeometry.
Reimplemented from vtkAreaPicker.
