3D widget for manipulating a tensor glyph
This 3D widget interacts with a vtkTensorRepresentation class (i.e., it handles the events that drive its corresponding representation). The widget is assumed to operate on a single 3x3 real, symmetric tensor located at a specified position. The tensor implicitly defines three orthogonal eigenvectors which indicate the orientation and relative scaling of the widget's representation.
The widget has the appearance of an oriented box with seven handles: one at the center of the box, and six located at the center of each face. The box can be translated by selecting its center handle; rotated by selecting and rotating one of the box faces around the box center; and scaled (in a particular direction) by selecting the face handles (located on each face) and moving the faces in/out in the direction of the face normal. Uniform scaling is also possible by (default) using the right mouse button (unless the binding has been redefined).
To use this widget, you generally pair it with a vtkTensorRepresentation (or a subclass). Various options are available in the representation for controlling the widgets' size and position; how the widget 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 one of the seven handles are selected:
LeftButtonPressEvent - select the appropriate handle
LeftButtonReleaseEvent - release the currently selected handle
MouseMoveEvent - move the handle
If one of the faces is selected:
LeftButtonPressEvent - select a box face
LeftButtonReleaseEvent - release the box face
MouseMoveEvent - rotate the box
In all the cases, independent of what is picked, the widget responds to the
following VTK events:
MiddleButtonPressEvent - translate the widget
MiddleButtonReleaseEvent - release the widget
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 vtkTensorWidget's widget events:
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
- Event Bindings:
- In turn, when these widget events are processed, the vtkTensorWidget 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)
