[vtkusers] Question reg. vtkLandmarkTransform

[Hendrik Belitz]

Deae members of the VTK community,

currently I'm trying to align two point clouds using vtkLandmarkTransform. 
This works very good, despite two things:
1.) There is no documentation for VTK_LANDMARK_AFFINE, so I have no clue what 
this is doing. I assume that shearing is included in the transformation, but 
I'm not sure about it. Does anybody of you know something about this?
2.) The isotropic scaling done by vtkLandmarkTransform in all cases gives me 
some bad results for distinct point clouds. Using anisotropic scaling could 
solve the problem. Is there any way to do this in VTK?

Regards
 Hendrik
