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.
