[vtkusers] How to generate a surface normal glyph for a triangle cell

[Elvis Dowson]

Hi Miguel,
                       I've got the Visualization Toolkit book (2nd &  
3rd editions) but not the VTK User's Guide.

I'm also going through the doxygen pages, and samples, etc, but the  
thing is somethings some of these basic things just escape me! I don't  
know if this solution is documented in the VTK User's Guide, but I am  
hoping posting to the user group might yield a solution.

For example, I managed to get the tcl code working, with a plane  
surface and generated the arrow glyph, but it's pointing in the wrong  
direction. I was hoping someone could help me correct it.

Best regards,

Elvis Dowson
