Detailed Description

find world x,y,z corresponding to display x,y,z

vtkWorldPointPicker is used to find the x,y,z world coordinate of a screen x,y,z. This picker cannot pick actors and/or mappers, it simply determines an x-y-z coordinate in world space. (It will always return a x-y-z, even if the selection point is not over a prop/actor.)

Warning
The PickMethod() is not invoked, but StartPickMethod() and EndPickMethod() are.

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.

Reimplemented from vtkAbstractPicker.

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 vtkAbstractPicker.

Perform the pick.

(This method overload's the superclass.)
