Hi 

I got the fitting process running and used it to estimate the umbilics and ridges on a triangular mesh. 

I have attached the images for the results I get for a torus with this mail. Can someone who has had an experience with using jet_fitting and umbilics/ridge estimation before, let me know if these look correct? 
I have used a 2-ring neighbourhood for estimating the umbilics and a third order approximation for the ridges. 

Also. does anyone know if the min and max elliptic edges will always connect the umbilics?

Sincerely
Priyamvad

Color Code:
Blue Sphere: Umbilic
Red Line: Max elliptic ridge
Yellow Line: Min elliptic ridge

Thanks everyone. I was sleeping in the other part of the world, hence the delay.
I had boost libraries for the incorrect VC version. Reinstalling solved the problem. Jet_fitting runs nicely now.

I will try and incorporate Monge_fitting for my mesh implementation today. My goal is to get all the umbilics on a mesh.

Thanks again
Priyamvad

Priyamvad has a *link* error. That is a different problem. Maybe the library
does not exist on the machine, or the library path is wrong.

Priyamvad, please answer the usual questions, so that we can help you:

At the very least, what is your compiler? It seems to be VC90, can you
confirm? What version of CGAL? Is your OS for x86 or x64?
