[Paraview] ellipsoid glyphs

[Syrkina Ekaterina]

Hello,

I'm new to paraview and vtk, and would like to use glyphs filter for  
3d visualization. More precisely, I have a 3d vtk mesh and 3x3  
matrices corresponding to each mesh vertex (matrices were obtained in  
matlab and are not stored to any of paraview file types). I need  
ellipsoids visualizing eigenvectors/eigenvalues of these matrices (for  
all mesh points or for a subset). Is there any straight forward way to  
do it?

I found spheres in glyphs filter, custom source glyph filter and  
vtkTensorGlyph class, which seem to be able to solve my problem. But I  
don't understand how to store my data and how to open them in  
paraview. Or do I have to create my own filter to use ellipsoid glyphs?

Thanks. Regards,
Katya
