[vtkusers] Marching Cubes

[lydia many]

Dear Mr Lorensen, Dear All,
I have two questions. It will be very appreciated if someone especially Mr 
lorensen could answer:
1.I saw the site of "making your own visible woman" and read all the steps 
to follow for the reconstruction but
As you know, for the vivible woman, there are sets of slices with diffrent 
pixel sizes. The reconstruction of such sets gives some misalgnements of the 
organ. How did you solve the problem?

2. I would like to use the marching cubes algorithm and the 3D model of the 
bone is very heavy even after decimation. Do you know if there is a variant 
of marching cubes that doesn't calculate internal isosurface.That means that 
I like to have just the outer isosuface and an empty bone.
