Hello,

I am running the example given at:

http://www.cgal.org/Manual/latest/examples/Surface_mesher/mesh_a_3d_gray_image.cpp

on my gray scale dataset. It produces proper surface triangulation most 
of the time but once in a while it seems it is recursively refining a 
particular part of the mesh so much that the output triangles are 
degenerate.
(I have attached a screen shot of the problem).

So my questions are:

- how do I avoid this ?
- is this related to type of kernel 
'Surface_mesh_default_triangulation_3' is using ? (how can I change the 
kernel?)
- The example talks about 'relative precision' in these lines :
   // definition of the surface, with 10^-5 as relative precision
   Surface_3 surface(image, bounding_sphere, 1e-5);

   What is it relative to ?

thanks in advance,
Hamid
