measure the angle between two rays (defined by three points)
The vtkAngleWidget is used to measure the angle between two rays (defined by three points). The three points (two end points and a center) can be positioned independently, and when they are released, a special PlacePointEvent is invoked so that special operations may be take to reposition the point (snap to grid, etc.) The widget has two different modes of interaction: when initially defined (i.e., placing the three points) and then a manipulate mode (adjusting the position of the three points).
To use this widget, specify an instance of vtkAngleWidget and a representation (a subclass of vtkAngleRepresentation). The widget is implemented using three instances of vtkHandleWidget which are used to position the three points. The representations for these handle widgets are provided by the vtkAngleRepresentation.
- Event Bindings:
- By default, the widget responds to the following VTK events (i.e., it watches the vtkRenderWindowInteractor for these events):
LeftButtonPressEvent - add a point or select a handle
MouseMoveEvent - position the second or third point, or move a handle
LeftButtonReleaseEvent - release the selected handle
- Event Bindings:
- Note that the event bindings described above can be changed using this class's vtkWidgetEventTranslator. This class translates VTK events into the vtkAngleWidget's widget events:
vtkWidgetEvent::AddPoint -- add one point; depending on the state
it may the first, second or third point
added. Or, if near a handle, select the handle.
vtkWidgetEvent::Move -- position the second or third point, or move the
handle depending on the state.
vtkWidgetEvent::EndSelect -- the handle manipulation process has completed.
- Event Bindings:
- This widget invokes the following VTK events on itself (which observers can listen for):
vtkCommand::StartInteractionEvent (beginning to interact)
vtkCommand::EndInteractionEvent (completing interaction)
vtkCommand::InteractionEvent (moving a handle)
vtkCommand::PlacePointEvent (after a point is positioned;
call data includes handle id (0,1,2))
