[vtkusers] Multiple scalars working together?

Have you thought of converting your scalar data into vector data with one
component equal to zero and the other two your velocity and direction. Perhaps
the vector data can be used more effectively to color or perhaps glyph your data
set. I've no experience with vector data so not much help there but there are
quite a few vector based examples if I remember right...john

Hi all,

I'm currently stuck at this problem: My data has two
scalars (there's no way to combine these two to one),
say, "direction" and "velocity". In my lookuptable I
want "direction" to determine the Hue and "velocity"
to determine the Value independently. Is it possibile
to do that and how? Or is there any other way to
assign color to a point in the polydata other than
using scalar and lookuptable?

Thank you for your help!

P
