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.
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
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

void vtkImplicitPlaneWidget2::SetRepresentation | ( | vtkImplicitPlaneRepresentation * | rep | ) |
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.
void vtkImplicitPlaneWidget2::SetLockNormalToCamera | ( | int | lock | ) |
Observe/Unobserve the camera if the widget is locked/unlocked to update the vtkImplicitePlaneRepresentation's normal.

Return the representation as a vtkImplicitPlaneRepresentation.
