Hi Laurent

you gave me a very good hint. I was wrong in data allocation in memory, I generate .inr file from a matlab script and it is now working. it is quite fast. Thank u and for CGAL TEAM for this nice piece of software

I will still be happy if you can tell me what was wrong in my code for the data allocation

Regards

Dear  ALL

I attached in the mail a slice from the mri volume that I need to mesh. The

slice has some 90 degree angles resulted from segmentation. I tried to use

make_mesh_3 to generate tetrahedron for this but it does not work. I did

not use any optimization in mesh criteria.

DO I miss something in the delaunay triangulation. I thought yesterday that

I should find away to control the divide and conquer during the mesh

generation. but I am not sure if this is right or wrong although I do not

have too much experience in the 3d delaunay triangulation.

Please, send us your code, or some parts of the code (that use CGAL), and the
data, or at least the header fields of your data.

With that information, there is a chance that we can give you an answer.

If the files are bigger than.. say 10Ko, please do not send the files as
attachment to the mailing list. Post it to a dedicated web site (dropbox for
example), or send the files directly to me (to avoid spamming the whole list
with big attachments).
