vtkImplicitPlaneWidget2 Class Reference
#include <vtkImplicitPlaneWidget2.h>
Detailed Description
3D widget for manipulating an infinite planeThis 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 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
- 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)
- Warning:
- Note that the widget can be picked even when it is "behind" other actors. This is an intended feature and not a bug.
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.
