[vtkusers] Unstructured grid example

[Karthik Mukundakrishnan]

Hi!

I'm a new user of VTK with Tcl/Tk interface. I was
wondering if someone could provide me with an example
of Tcl code to visualize an unstructured 3-D grid made
of tetrahedrons. I have the datafile in the specified
vtk file format. I'm finding it difficult to view the
grid because I'm not sure of what command to use to
extract the griddata although I use
vtkUnstructuredGridreader command. Someone kindly
help. 

Thanks in advance,
Karthik.
