#include <itkSimplexMeshVolumeCalculator.h>

Detailed Description

template<typename TInputMesh>
class itk::SimplexMeshVolumeCalculator< TInputMesh >

Adapted from itkSimplexMeshToTriangleFilter to calculate the volume of a simplex mesh using the barycenters and normals. call Compute() to calculate the volume and GetVolume() to get the value. For an example see itkDeformableSimplexMesh3DFilter.cxx (Thomas Boettger. Division Medical and Biological Informatics, German Cancer Research Center, Heidelberg.)

Author: Leila Baghdadi MICe, Hospital for Sick Children, Toronto, Canada.

The original implementation has been replaced with an algorithm based on the discrete form of the divergence theorem. The general assumption here is that the model is of closed surface. For more details see the following reference (Alyassin A.M. et al, "Evaluation of new algorithms for the interactive measurement of surface area and volume", Med Phys 21(6) 1994.).
