3D widget for manipulating a point on a sphere
This 3D widget interacts with a vtkSphereRepresentation class (i.e., it handles the events that drive its corresponding representation). It can be used to position a point on a sphere (for example, to place a light or camera), or to position a sphere in a scene, including translating and scaling the sphere.
A nice feature of vtkSphereWidget2, like any 3D widget, is that it will work in combination with the current interactor style (or any other interactor observer). That is, if vtkSphereWidget2 does not handle an event, then all other registered observers (including the interactor style) have an opportunity to process the event. Otherwise, the vtkSphereWidget2 will terminate the processing of the event that it handles.
To use this widget, you generally pair it with a vtkSphereRepresentation (or a subclass). Variuos options are available in the representation for controlling how the widget appears, and how the widget functions.
If the handle or sphere are selected: LeftButtonPressEvent - select the handle or sphere LeftButtonReleaseEvent - release the handle ot sphere MouseMoveEvent - move the handle or translate the sphere In all the cases, independent of what is picked, the widget responds to the following VTK events: MiddleButtonPressEvent - translate the representation MiddleButtonReleaseEvent - stop translating the representation RightButtonPressEvent - scale the widget's representation RightButtonReleaseEvent - stop scaling the representation MouseMoveEvent - scale (if right button) or move (if middle button) the widget
vtkWidgetEvent::Select -- some part of the widget has been selected vtkWidgetEvent::EndSelect -- the selection process has completed vtkWidgetEvent::Scale -- some part of the widget has been selected vtkWidgetEvent::EndScale -- the selection process has completed vtkWidgetEvent::Translate -- some part of the widget has been selected vtkWidgetEvent::EndTranslate -- the selection process has completed vtkWidgetEvent::Move -- a request for motion has been invoked

Specify an instance of vtkWidgetRepresentation used to represent this widget in the scene. Note that the representation is a subclass of vtkProp so it can be added to the renderer independent of the widget.
