// .NAME vtkCameraRepresentation - represent the vtkCameraWidget
// .SECTION Description
// This class provides support for interactively saving a series of camera
// views into an interpolated path (using vtkCameraInterpolator). The class
// typically works in conjunction with vtkCameraWidget. To use this class
// simply specify the camera to interpolate and use the methods
// AddCameraToPath(), AnimatePath(), and InitializePath() to add a new camera
// view, animate the current views, and initialize the interpolation.
// .SECTION See Also
// vtkCameraWidget vtkCameraInterpolator
