Detailed Description

create a contour with a set of points

The vtkContourWidget is used to select a set of points, and draw lines between these points. The contour may be opened or closed, depending on how the last point is added. The widget handles all processing of widget events (that are triggered by VTK events). The vtkContourRepresentation is responsible for all placement of the points, calculation of the lines, and contour manipulation. This is done through two main helper classes: vtkPointPlacer and vtkContourLineInterpolator. The representation is also responsible for drawing the points and lines.

Event Bindings:
By default, the widget responds to the following VTK events (i.e., it watches the vtkRenderWindowInteractor for these events):
  LeftButtonPressEvent - triggers a Select event
  RightButtonPressEvent - triggers a AddFinalPoint event
  MouseMoveEvent - triggers a Move event
  LeftButtonReleaseEvent - triggers an EndSelect event
  Delete key event - triggers a Delete event
  Shift + Delete key event - triggers a Reset event
Event Bindings:
Note that the event bindings described above can be changed using this class's vtkWidgetEventTranslator. This class translates VTK events into the vtkContourWidget's widget events:
  vtkWidgetEvent::Select
       widget state is:
           Start or
           Define: If we already have at least 2 nodes, test
                whether the current (X,Y) location is near an existing
                node. If so, close the contour and change to Manipulate
                state. Otherwise, attempt to add a node at this (X,Y)
                location.
           Manipulate: If this (X,Y) location activates a node, then
                set the current operation to Translate. Otherwise, if
                this location is near the contour, attempt to add a
                new node on the contour at this (X,Y) location.
Event Bindings:
  vtkWidgetEvent::AddFinalPoint
       widget state is:
           Start: Do nothing.
           Define: If we already have at least 2 nodes, test
                whether the current (X,Y) location is near an existing
                node. If so, close the contour and change to Manipulate
                state. Otherwise, attempt to add a node at this (X,Y)
                location. If we do, then leave the contour open and
                change to Manipulate state.
           Manipulate: Do nothing.
Event Bindings:
  vtkWidgetEvent::Move
       widget state is:
           Start or
           Define: Do nothing.
           Manipulate: If our operation is Translate, then invoke
                 WidgetInteraction() on the representation. If our
                 operation is Inactive, then just attempt to activate
                 a node at this (X,Y) location.
Event Bindings:
  vtkWidgetEvent::EndSelect
       widget state is:
           Start or
           Define: Do nothing.
           Manipulate: If our operation is not Inactive, set it to
                 Inactive.
Event Bindings:
  vtkWidgetEvent::Delete
       widget state is:
           Start: Do nothing.
           Define: Remove the last point on the contour.
           Manipulate: Attempt to activate a node at (X,Y). If
                  we do activate a node, delete it. If we now
                  have less than 3 nodes, go back to Define state.
Event Bindings:
  vtkWidgetEvent::Reset
       widget state is:
           Start: Do nothing.
           Define: Remove all points and line segments of the contour.
                Essentially calls Initialize(NULL)
           Manipulate: Do nothing.
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 after selecting something)
  vtkCommand::PlacePointEvent (after point is positioned;
                               call data includes handle id (0,1))
  vtkCommand::WidgetValueChangedEvent (Invoked when the contour is closed
                                       for the first time. )

If you do not want to see the last active node as it is being added, set the opacity to 0 of the representation's active property.

)
virtual

Initialize the contour widget from a user supplied set of points.

The state of the widget decides if you are still defining the widget, or if you've finished defining (added the last point) are manipulating it. Note that if the polydata supplied is closed, the state will be set to manipulate. State: Define = 0, Manipulate = 1.
