Detailed Description
a nonlinear warp transformation
vtkGridTransform describes a nonlinear warp transformation as a set of displacement vectors sampled along a uniform 3D grid.
- Warning:
- The inverse grid transform is calculated using an iterative method, and is several times more expensive than the forward transform.
