Maybe I wasn't specific enough about my data and it was confusing.<br>I have point data witch represent centers of ellipsoidal cells. With each point there are associated lengths of ellipsoid axes (e.g. as a vector data), which can be different for each ellipsoid, and directions of those axes in space (3 vectors). I want to display those ellipsoids oriented and in appropriate scale.<br>So I was thinking: I need to scale spheres anisotropically to get ellipsoids so I really need to do it by scaling with vector components of the scales/axes_length vector. Scaling by scalars works isotropically so it won't help. Now I need to align
axes of each ellipsoid in space. I probably need to do it by programmable filter, but I don't know how to operate on separate glyphs (ellipsoids) and their data. Did anyone have similar problem and solved it somehow?<br>Thanks.<br>Pawel <br><br> >mirko heuegger</strong> wrote<br>>I suggest that you 'convert' one vector data into a scalar (e.g. over<br>>the Calculator-filter, and by using the functions: mag(<vector>),<br>>iHat.<vector>, jHat.<vector>, or kHat.<vector> (magnitude, X, Y, and Z<br>>of a vector) for calculating the desired vector-parts).<br>>Then change the 'Scale Mode', of the Glyph-filter, to 'scalar', and<br>>select the calculation-result as scalar-field.</div></div><br>
