Detailed Description

ray-cast cell picker for the reslice cursor

This class is used by the vtkResliceCursorWidget to pick reslice axes drawn by a vtkResliceCursorActor. The class returns the axes picked if any, whether one has picked the center. It takes as input an instance of vtkResliceCursorPolyDataAlgorithm. This is all done internally by vtkResliceCursorWidget and as such users are not expected to use this class directly, unless they are overriding the behaviour of vtkResliceCursorWidget.
