[Insight-users] Triangular Mesh Data structure

[Deepak Roy]

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
