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.

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 the pick. (This method overload's the superclass.)
