Detailed Description

perform affine transformations

The vtkAffineWidget is used to perform affine transformations on objects. (Affine transformations are transformations that keep parallel lines parallel. Affine transformations include translation, scaling, rotation, and shearing.)

To use this widget, set the widget representation. The representation maintains a transformation matrix and other instance variables consistent with the transformations applied by this widget.

Event Bindings:

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

  LeftButtonPressEvent - select widget: depending on which part is selected
                         translation, rotation, scaling, or shearing may follow.
  LeftButtonReleaseEvent - end selection of widget.
  MouseMoveEvent - interactive movement across 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 vtkAffineWidget's widget events:

  vtkWidgetEvent::Select -- focal point is being selected
  vtkWidgetEvent::EndSelect -- the selection process has completed
  vtkWidgetEvent::Move -- a request for widget motion

Event Bindings:

In turn, when these widget events are processed, the vtkAffineWidget 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)

Events:: vtkCommand::InteractionEvent vtkCommand::StartInteractionEvent vtkCommand::EndInteractionEvent
