// .NAME vtkLandmarkTransform - a linear transform specified by two corresponding point sets
// .SECTION Description
// A vtkLandmarkTransform is defined by two sets of landmarks, the
// transform computed gives the best fit mapping one onto the other, in a
// least squares sense. The indices are taken to correspond, so point 1
// in the first set will get mapped close to point 1 in the second set,
// etc. Call SetSourceLandmarks and SetTargetLandmarks to specify the two
// sets of landmarks, ensure they have the same number of points.
// .SECTION Caveats
// Whenever you add, subtract, or set points you must call Modified()
// on the vtkPoints object, or the transformation might not update.
// .SECTION see also
