Detailed Description

a linear transform specified by two corresponding point sets

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.

Warning

Whenever you add, subtract, or set points you must call Modified() on the vtkPoints object, or the transformation might not update.
