[vtkusers] Filling in blood vessels

[Gib Bogle]

I've just started to become aware of the image-processing capabilities  
of VTK, and I'm wondering if I can use it for some tasks that I was  
expecting to use Amira for.  We are generating images in which the  
walls of blood vessels are stained, so that the vessels appear in 3D  
as tubes.  I believe the first processing step I need to make is to  
"fill in" the vessels, i.e. generate a thresholded 3D image in which  
the vessels appear solid.  Is this the kind of thing that VTK can  
handle?

Thanks
Gib
