Thank you for your reply.. I am getting compilation errors. I understand
that they are coming while I am reading the image. specifically read
function in CGAL.


I am trying to read a 3d labelled voxels and trying to mesh it as complete
3d and 3d surface. I am successful in generating full 3d mesh but not 3d
surface mesh.


For complete 3d image I followed same steps as liver example in CGAL.
In CGAL 3d meshing example, reading an image is performed by the following
steps 

  // Loads image
  CGAL::Image_3 image;
  image.read("data/liver.inr.gz");
 
 // Domain
  Mesh_domain domain(image);




But in 3d surface meshing example 

// the 'function' is a 3D gray level image
Gray_level_image image("data/skull_2.9.inr", 2.9f);



Could you explain what is the difference between 3d surface mesh and 3d mesh
in-terms of reading the image into CGAL.
