Hi,I'm stuck with a problem concerning colors assignment to data.I've a list of
8 tensors (here represented as circular ellipsoids, see short vtk file below)I
typically open the file and filter using ("tensor glyph").Now I would like to
assign to each tensor glyph a unique color specified by an rgba sequence (e.g.
0.1 0.3 0.2 1)How can I do that? I tried to append a scalar lookup table
followed by a rgba one but without successThanks -Claudio
