If it takes hours, it probably means that the input is not manifold
and the mesher cannot make something non-manifold manifold.

I think I already saw that while meshing grey images and it was due
to noise or a too large range of the grey level values.

If you provide a program we can compile and run somebody might be able
to have a look at it if you can't find out.

Best,

Sebastien
