Instead of vector glyphs, I would like to use ellipsoidal shapes based on a scalar factor. Each ellipse should be different which prevents the use of the Custom Glyph filter. Is there any code which will allow me to do this?

Hi @jkim ,
Tensor glyph creates these kind of shapes, but you will have to compute the corresponding tensors.

Would I need to compute them in the vtk file? How do I do this in Paraview using the paraview.Simple.TensorGlyph?

These three VTK Examples may give you some ideas:
