[vtkusers] Tissue damage rendering

[Yasser Bashir]

Hi,

I am trying to simulate damage in tissues geometrically represented as
unstructuredgrids with tetrahedral cells.

I have written a filter which calculates the intensity of damage in
cells as it propagates through the tissue.  However, I don't know of a
neat way to render the mesh while the damage is being calculated for
each cell and the scalar damage value is being set for it.  

I am only able to see the final set of damaged cells when the filter
execution is complete.   

Is there ANY way at all in VTK to see my damage growing as the filter
marks more cells in the unstructured grid as damaged??

Regards.
