Hi VTK users,

I would like to use one of VTK's implementations of the marching cubes algorithm and would like to know, if it is possible to use one of the algorithms with non binary images (e.g. CT or MR data) by setting a threshold value. 
Moreover, it would be interesting if the algorithms also perform step 5 of the summary of Mr. Lorensen' s paper(Marching cubes: Ahigh resolution 3D surface construction algorithm"): "Using the densities at each vertex, find the surface-edge intersection via linear interpolation"?

Thank you,

Karl Fritscher
