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

Super Class: vtkPicker

Description:

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 computes an x-y-z coordinate in world space (so the actor and mapper are set to NULL).

 

Caveats:

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