double GetMaximumT()
Obtain some information about the interpolation range.
void InterpolateQuaternion(double t, vtkQuaterniond &q)

void AddQuaternion(double t, const vtkQuaterniond &q)
Add another quaternion to the list of quaternions to be interpolated.
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
void SetInterpolationTypeToLinear()
Specify which type of function to use for interpolation.
void Initialize()
Reset the class so that it contains no data; i.e., the array of (t,q[4]) information is discarded.
void RemoveQuaternion(double t)
Delete the quaternion at a particular parameter t.
double GetMinimumT()
Obtain some information about the interpolation range.
int GetSearchMethod()
Set / Get the search type method.
void AddQuaternion(double t, double q[4])
Add another quaternion to the list of quaternions to be interpolated.
static vtkQuaternionInterpolator * New()
Instantiate the class.
void SetInterpolationTypeToSpline()
Specify which type of function to use for interpolation.
int GetNumberOfQuaternions()
Return the number of quaternions in the list of quaternions to be interpolated.
