interpolate a series of transformation matrices
This class is used to interpolate a series of 4x4 transformation matrices. Position, scale and orientation (i.e., rotations) are interpolated separately, and can be interpolated linearly or with a spline function. Note that orientation is interpolated using quaternions via SLERP (spherical linear interpolation) or the special vtkQuaternionSpline class.
To use this class, specify at least two pairs of (t,transformation matrix) with the AddTransform() method. Then interpolated the transforms with the InterpolateTransform(t,transform) method, where "t" must be in the range of (min,max) times specified by the AddTransform() method.
By default, spline interpolation is used for the interpolation of the transformation matrices. The position, scale and orientation of the matrices are interpolated with instances of the classes vtkTupleInterpolator (position,scale) and vtkQuaternionInterpolator (rotation). The user can override the interpolation behavior by gaining access to these separate interpolation classes. These interpolator classes (vtkTupleInterpolator and vtkQuaternionInterpolator) can be modified to perform linear versus spline interpolation, and/or different spline basis functions can be specified.
- Warning
- The interpolator classes are initialized when the InterpolateTransform() is called. Any changes to the interpolators, or additions to the list of transforms to be interpolated, causes a reinitialization of the interpolators the next time InterpolateTransform() is invoked. Thus the best performance is obtained by 1) configuring the interpolators, 2) adding all the transforms, and 3) finally performing interpolation.
