|
||
|
|
* vtkPropPicker3D is used to pick an actor/prop given a selection
|
||
|
|
* point in world coordinates.
|
||
|
|
* This class determines the actor/prop and pick position in world
|
||
|
|
* coordinates; point and cell ids are not determined.
|
||
|
|
* This is useful for VRE devices that provide 3D positions
|
||
|
|
* directly via the vtkRenderWindowInteractor3D. It is the default
|
||
|
|
* picker for the vtkInteractorStyle3D
