[vtkusers] Rectangular Prism Registration Using Iterative Closest Point

[EdwardWang]

Hi all,

I am trying to register two rectangular prism polygon meshes using vtk's ICP
implementation. One is created using vtkCubeSource, and the other is an
imported STL file. The dimensions are very similar, although not identical.
In most cases, the results are as expected; the two rectangular prisms
overlaid over each other. However, in some cases, the the models are
overlaid perpendicular to each other (see attached image). Any thoughts as
to what's causing this, and if it's possible to fix? I am working in
Slicer3d.

Thank you,
Edward
