Detailed Description
a nonlinear warp transformation
- Date:
-
2002/01/22 15:30:39
- Revision:
-
1.22
vtkThinPlateSplineTransform describes a nonlinear warp transform defined by a set of source and target landmarks. Any point on the mesh close to a source landmark will be moved to a place close to the corresponding target landmark. The points in between are interpolated smoothly using Bookstein's Thin Plate Spline algorithm.
- Warning:
-
1) The inverse transform is calculated using an iterative method, and is several times more expensive than the forward transform. 2) Whenever you add, subtract, or set points you must call Modified() on the vtkPoints object, or the transformation might not update. 3) Collinear point configurations (except those that lie in the XY plane) result in an unstable transformation.
