static vtkCameraInterpolator * New()
Instantiate the class.
vtkTupleInterpolator * ViewUpInterpolator
vtkTupleInterpolator * ViewAngleInterpolator

Set/Get the tuple interpolator used to interpolate the view angle portion of the camera.
double GetMinimumT()
Obtain some information about the interpolation range.
void InterpolateCamera(double t, vtkCamera *camera)
Interpolate the list of cameras and determine a new camera (i.e., fill in the camera provided).
void SetInterpolationTypeToManual()
These are convenience methods to switch between linear and spline interpolation.
double GetMaximumT()
Obtain some information about the interpolation range.
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
