My demand is about two aspects: (1) when rendering in window,different areas must be distinguished by different colors;(2)when I write my output file of vertex coordinates,I must have ability to choose the data of which area to be output.

Doing this without discriminating disconnected volumes is trivially
simple, but the marching cube filter actually transforms every non-null
voxel into a mesh! Maybe can we detect cycles in the vtkPolydata
structure and move them in different structures??
