#include <vtkThinPlateSplineTransform.h>
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.
To obtain a correct TPS warp, use the R2LogR kernel if your data is 2D, and the R kernel if your data is 3D. Or you can specify your own RBF. (Hence this class is more general than a pure TPS transform.)

virtual const char* vtkThinPlateSplineTransform::GetClassName | ( | ) | [virtual] |
Reimplemented from vtkWarpTransform.
static int vtkThinPlateSplineTransform::IsTypeOf | ( | const char * | name | ) | [static] |
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.
Reimplemented from vtkWarpTransform.
virtual int vtkThinPlateSplineTransform::IsA | ( | const char * | name | ) | [virtual] |
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.

void vtkThinPlateSplineTransform::PrintSelf | ( | ostream & | os, | |
vtkIndent | indent | |||
) | [virtual] |
Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.
Reimplemented from vtkWarpTransform.
static vtkThinPlateSplineTransform* vtkThinPlateSplineTransform::New | ( | ) | [static] |
Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

virtual double vtkThinPlateSplineTransform::GetSigma | ( | ) | [virtual] |
Specify the 'stiffness' of the spline. The default is 1.0.

Specify the 'stiffness' of the spline. The default is 1.0.
void vtkThinPlateSplineTransform::SetBasis | ( | int | basis | ) |
Specify the radial basis function to use. The default is R2LogR which is appropriate for 2D. Use |R| (SetBasisToR) if your data is 3D. Alternatively specify your own basis function, however this will mean that the transform will no longer be a true thin-plate spline.

Specify the radial basis function to use. The default is R2LogR which is appropriate for 2D. Use |R| (SetBasisToR) if your data is 3D. Alternatively specify your own basis function, however this will mean that the transform will no longer be a true thin-plate spline.
