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.

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 vtkObject.

◆ Pick() [1/2]

int vtkResliceCursorPicker::Pick	(	double	selectionX,

Perform pick operation with selection point provided.

Normally the first two values are the (x,y) pixel coordinates for the pick, and the third value is z=0. The return value will be non-zero if something was successfully picked.

Implements vtkAbstractPicker.
