Detailed Description

a cubic b-spline deformation transformation

vtkBSplineTransform computes a cubic b-spline transformation from a grid of b-spline coefficients.

Warning: The inverse grid transform is calculated using an iterative method, and is several times more expensive than the forward transform.
