The interpolation may be linear in form (using spherical linear interpolation SLERP), or via spline interpolation (using SQUAD). In either case the interpolation is specialized to quaternions since the interpolation occurs on the surface of the unit quaternion sphere. To use this class, specify at least two pairs of (t,q[4]) with the AddQuaternion() method. Next interpolate the tuples with the InterpolateQuaternion(t,q[4]) method, where "t" must be in the range of (t_min,t_max) parameter values specified by the AddQuaternion() method (t is clamped otherwise), and q[4] is filled in by the method. There are several important background references. Ken Shoemake described the practical application of quaternions for the interpolation of rotation (K. Shoemake, "Animating rotation with quaternion curves", Computer Graphics (Siggraph '85) 19(3):245--254, 1985). Another fine reference (available on-line) is E. B. Dam, M. Koch, and M. Lillholm, Technical Report DIKU-TR-98/5, Dept. of Computer Science, University of Copenhagen, Denmark. @warning Note that for two or less quaternions, Slerp (linear) interpolation is performed even if spline interpolation is requested. Also, the tangents to the first and last segments of spline interpolation are (arbitrarily) defined by repeating the first and last quaternions. @warning There are several methods particular to quaternions (norms, products, etc.) implemented interior to this class. These may be moved to a separate quaternion class at some point. @sa vtkQuaternion vtkCommonMathPython.vtkQuaternionInterpolatorV.IsTypeOf(string) -> int C++: static vtkTypeBool IsTypeOf(const char *type) Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h. V.IsA(string) -> int C++: vtkTypeBool IsA(const char *type) override; Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h. V.SafeDownCast(vtkObjectBase) -> vtkQuaternionInterpolator C++: static vtkQuaternionInterpolator *SafeDownCast( vtkObjectBase *o) V.NewInstance() -> vtkQuaternionInterpolator C++: vtkQuaternionInterpolator *NewInstance() V.GetNumberOfQuaternions() -> int C++: int GetNumberOfQuaternions() Return the number of quaternions in the list of quaternions to be interpolated. V.GetMinimumT() -> float C++: double GetMinimumT() Obtain some information about the interpolation range. The numbers returned (corresponding to parameter t, usually thought of as time) are undefined if the list of transforms is empty. This is a convenience method for interpolation. V.GetMaximumT() -> float C++: double GetMaximumT() Obtain some information about the interpolation range. The numbers returned (corresponding to parameter t, usually thought of as time) are undefined if the list of transforms is empty. This is a convenience method for interpolation. V.Initialize() C++: void Initialize() Reset the class so that it contains no data; i.e., the array of (t,q[4]) information is discarded. V.AddQuaternion(float, vtkQuaterniond) C++: void AddQuaternion(double t, const vtkQuaterniond &q) V.AddQuaternion(float, [float, float, float, float]) C++: void AddQuaternion(double t, double q[4]) Add another quaternion to the list of quaternions to be interpolated. Note that using the same time t value more than once replaces the previous quaternion at t. At least one quaternions must be added to define an interpolation functios. V.RemoveQuaternion(float) C++: void RemoveQuaternion(double t) Delete the quaternion at a particular parameter t. If there is no quaternion tuple defined at t, then the method does nothing. V.InterpolateQuaternion(float, vtkQuaterniond) C++: void InterpolateQuaternion(double t, vtkQuaterniond &q) V.InterpolateQuaternion(float, [float, float, float, float]) C++: void InterpolateQuaternion(double t, double q[4]) Interpolate the list of quaternions and determine a new quaternion (i.e., fill in the quaternion provided). If t is outside the range of (min,max) values, then t is clamped to lie within the range. V.SetInterpolationType(int) C++: virtual void SetInterpolationType(int _arg) Specify which type of function to use for interpolation. By default (SetInterpolationFunctionToSpline()), cubic spline interpolation using a modified Kochanek basis is employed. Otherwise, if SetInterpolationFunctionToLinear() is invoked, linear spherical interpolation is used between each pair of quaternions. V.GetInterpolationTypeMinValue() -> int C++: virtual int GetInterpolationTypeMinValue() Specify which type of function to use for interpolation. By default (SetInterpolationFunctionToSpline()), cubic spline interpolation using a modified Kochanek basis is employed. Otherwise, if SetInterpolationFunctionToLinear() is invoked, linear spherical interpolation is used between each pair of quaternions. V.GetInterpolationTypeMaxValue() -> int C++: virtual int GetInterpolationTypeMaxValue() Specify which type of function to use for interpolation. By default (SetInterpolationFunctionToSpline()), cubic spline interpolation using a modified Kochanek basis is employed. Otherwise, if SetInterpolationFunctionToLinear() is invoked, linear spherical interpolation is used between each pair of quaternions. V.GetInterpolationType() -> int C++: virtual int GetInterpolationType() Specify which type of function to use for interpolation. By default (SetInterpolationFunctionToSpline()), cubic spline interpolation using a modified Kochanek basis is employed. Otherwise, if SetInterpolationFunctionToLinear() is invoked, linear spherical interpolation is used between each pair of quaternions. V.SetInterpolationTypeToLinear() C++: void SetInterpolationTypeToLinear() Specify which type of function to use for interpolation. By default (SetInterpolationFunctionToSpline()), cubic spline interpolation using a modified Kochanek basis is employed. Otherwise, if SetInterpolationFunctionToLinear() is invoked, linear spherical interpolation is used between each pair of quaternions. V.SetInterpolationTypeToSpline() C++: void SetInterpolationTypeToSpline() Specify which type of function to use for interpolation. By default (SetInterpolationFunctionToSpline()), cubic spline interpolation using a modified Kochanek basis is employed. Otherwise, if SetInterpolationFunctionToLinear() is invoked, linear spherical interpolation is used between each pair of quaternions.
