#include <itkSimplexMesh.h>

Detailed Description

template<typename TPixelType, unsigned int VDimension = 3, typename TMeshTraits = DefaultStaticMeshTraits<TPixelType, VDimension, VDimension, TPixelType, TPixelType, TPixelType>>
class itk::SimplexMesh< TPixelType, VDimension, TMeshTraits >

The class represents a 2-simplex mesh.

A simplex mesh can be used for deformable model segmentation of 3D image data. To create a simplex mesh one needs a triangle mesh, which can be converted to using the class itkTriangleMeshToSimplexMeshFilter. The back filtering (from simplex to triangle mesh)is done through a itkSimplexMeshToTriangleMeshFilter.
