* @class vtkWorldPointPicker
|
|
* @brief 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.
