How to extract isosurfaces from multi-regional image volumes (implementation of Multiple material marching cubes or any other similar algorithm)

Hello,

I want to know whether MATLAB have an implementation of the multiple material marching cubes algorithm (International Journal of Numerical Methods in Engineering 2003; 58:189–207) for isosurface extraction of multiregion image volumes? or do there exist open source codes of any other related algorithm? By multiple material marching cubes, I mean creating contiguous 3D surfaces for as many materials(iso-surfaces) requested within a single sweep of an image volume.

Any help will be highly appreciated

Thanks
