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.
