[Insight-developers] ComputeNormal : itk::SimplexMesh

[Luis Ibanez]

Hi Thomas,


Why is the "ComputeNormal()" method of the
itkSimplexMesh returning a PointType ?

http://www.itk.org/Insight/Doxygen/html/classitk_1_1SimplexMesh.html#itk_1_1SimplexMesha5

A Normal should be returned as a CovariantVector,
in order to be consistent under AffineTransforms.


I would suggest we change the return type.



Please let us know,


     Thanks


        Luis
