Another worthy alternative would be the OpenMesh library:

Onderwerp: [vtkusers] Triangular Mesh Datastructure
 
Hello,
 
I am confronted with a graphics problem, to be more specific 3D
Segmentation of Triangular Surface Meshes.
 
The data is in the format of vrml files.
 
I am in search of a library, that supports the following:
 
*         A Robust Triangular Mesh Data Structure that stores vertices,
faces, texture indices and texels, vertex-edge-face adjacency
*         Examining n-ring neighborhood of a vertex
*         Computing vertex curvatures
*         Mesh import from a vrml file
*         Connected component analysis of the mesh
*         Access to vertex and face normals
*         Sub mesh extraction
*         Affine Transformations on the mesh
 
I came to know that ITK has a mesh class that implements a very basic
version of the mesh datastructure and also has some mesh filters.
 
Is it a good idea to use itk::mesh to facilitate the needs mentioned
above ?  
 
Are any mesh segmentation algorithms being added to future versions of
ITK ?
 
I also heard VTK has some support for the meshes, but apparently VTK
does not incorporate any mesh segmentation algorithms. The VTK CVS seems
to support vrml import but not the stable release.
 
Are there any other libraries 
I need your suggestions...
 
Thanks in advance.
 
Bye
 
Deepak
