[Insight-users] Calculate exact surface

[Luis Ibanez]

Hi Thomas,

You may want to use the
http://www.itk.org/Insight/Doxygen/html/classitk_1_1SimplexMeshVolumeCalculator.html

The code is in

     Insight/Code/Algorithms/
        itkSimplexMeshVolumeCalculator.h*
        itkSimplexMeshVolumeCalculator.txx


Take a look at the GetArea() method.

You may need to use also the filter:

http://www.itk.org/Insight/Doxygen/html/classitk_1_1TriangleMeshToSimplexMeshFilter.html

in order to get the intermediate simples mesh.



   Regards,


      Luis
