[Insight-users] calculate normal

[Luis Ibanez]

Hi Tony,


Well.... if you only have a point, then there is no normal to compute.

You probably are thinking of a point from a surface, where a point
belongs to several faces and have other points as neighbors.


In that case you may want to look at the itk::SimplexMesh
http://www.itk.org/Insight/Doxygen/html/classitk_1_1SimplexMesh.html

and its "ComputeNormal" method:

    Regards,


       Luis
