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 plane normal is selected:
   LeftButtonPressEvent - select normal
   LeftButtonReleaseEvent - release normal
   MouseMoveEvent - orient the normal vector
 If the origin point is selected:
   LeftButtonPressEvent - select slider (if on slider)
   LeftButtonReleaseEvent - release slider (if selected)
   MouseMoveEvent - move the origin point (constrained to the plane)
 If the plane is selected:
   LeftButtonPressEvent - select slider (if on slider)
   LeftButtonReleaseEvent - release slider (if selected)
   MouseMoveEvent - move the plane
 If the outline is selected:
   LeftButtonPressEvent - select slider (if on slider)
   LeftButtonReleaseEvent - release slider (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 slider 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.

Standard vtkObject methods

Reimplemented from vtkAbstractWidget.

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.

Reimplemented from vtkAbstractWidget.

Observe/Unobserve the camera if the widget is locked/unlocked to update the vtkImplicitePlaneRepresentation's normal.

Return the representation as a vtkImplicitPlaneRepresentation.

Create the default widget representation if one is not set.

int vtkImplicitPlaneWidget2::UpdateCursorShape ( int  interactionState) [protected]

Update the cursor shape based on the interaction state. Returns 1 if the cursor shape requested is different from the existing one.
