// .NAME vtkCameraWidget - 2D widget for saving a series of camera views
// .SECTION Description
// This class provides support for interactively saving a series of camera
// views into an interpolated path (using vtkCameraInterpolator). To use the
// class start by specifying a camera to interpolate, and then simply start
// recording by hitting the "record" button, manipulate the camera (by using
// an interactor, direct scripting, or any other means), and then save the
// camera view. Repeat this process to record a series of views. The user
// can then play back interpolated camera views using the
// vtkCameraInterpolator.
// .SECTION See Also
// vtkBorderWidget vtkCameraInterpolator

// Description:
// 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.
void SetRepresentation(vtkCameraRepresentation *r)

// Description:
// Create the default widget representation if one is not set.

~vtkCameraWidget();
// Description:
// When selecting the interior of this widget, special operations occur
// (i.e., adding a camera view, deleting a path, animating a path). Thus
// this methods overrides the superclasses' method.
