Detailed Description

3D widget for manipulating an infinite plane

This 3D widget defines an infinite plane that can be interactively placed in a scene. The widget is assumed to consist of four parts: 1) a plane contained in a 2) bounding box, with a 3) plane normal, which is rooted at a 4) point on the plane. (The representation paired with this widget determines the actual geometry of the widget.)

To use this widget, you generally pair it with a vtkImplicitPlaneRepresentation (or a subclass). Variuos options are available for controlling how the representation appears, and how the widget functions.

Event Bindings:

By default, the widget responds to the following VTK events (i.e., it watches the vtkRenderWindowInteractor for these events):

If the mouse is over the plane normal:
  LeftButtonPressEvent - select normal
  LeftButtonReleaseEvent - release normal
  MouseMoveEvent - orient the normal vector
If the mouse is over the origin point (handle):
  LeftButtonPressEvent - select handle
  LeftButtonReleaseEvent - release handle (if selected)
  MouseMoveEvent - move the origin point (constrained to the plane)
If the mouse is over the plane:
  LeftButtonPressEvent - select plane
  LeftButtonReleaseEvent - release plane (if selected)
  MouseMoveEvent - move the plane
If the mouse is over the outline:
  LeftButtonPressEvent - select outline
  LeftButtonReleaseEvent - release outline (if selected)
  MouseMoveEvent - move the outline
If the keypress characters are used
  'Down/Left' Move plane down
  'Up/Right' Move plane up
In all the cases, independent of what is picked, the widget responds to the
following VTK events:
  MiddleButtonPressEvent - move the plane
  MiddleButtonReleaseEvent - release the plane
  RightButtonPressEvent - scale the widget's representation
  RightButtonReleaseEvent - stop scaling the widget
  MouseMoveEvent - scale (if right button) or move (if middle button) the widget

Event Bindings:

Note that the event bindings described above can be changed using this class's vtkWidgetEventTranslator. This class translates VTK events into the vtkImplicitPlaneWidget2's widget events:

  vtkWidgetEvent::Select -- some part of the widget has been selected
  vtkWidgetEvent::EndSelect -- the selection process has completed
  vtkWidgetEvent::Move -- a request for widget motion has been invoked
  vtkWidgetEvent::Up and vtkWidgetEvent::Down -- MovePlaneAction

Event Bindings:

In turn, when these widget events are processed, the vtkImplicitPlaneWidget2 invokes the following VTK events on itself (which observers can listen for):

  vtkCommand::StartInteractionEvent (on vtkWidgetEvent::Select)
  vtkCommand::EndInteractionEvent (on vtkWidgetEvent::EndSelect)
  vtkCommand::InteractionEvent (on vtkWidgetEvent::Move)

Event Bindings:: This class, and vtkImplicitPlaneRepresentation, are next generation VTK widgets. An earlier version of this functionality was defined in the class vtkImplicitPlaneWidget.

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.

Methods for activating this widget.

Note that the widget representation must be specified or the widget will not appear. ProcessEvents (On by default) must be On for Enabled widget to respond to interaction. If ProcessEvents is Off, enabling/disabling a widget merely affects the visibility of the representation.
