Thanks for your reply! Luminosity does the job of emitting the light well 
The only thing is that the object itself will be uniformly its Solid Color (albeit illuminated). For example:
It would be really great if I could somehow make the inner sphere (which is the object with a non-zero luminosity) appear to be glowing. In the tweeted image I see that effect working out really nicely for the yellow streamline (it has a bit of a faded glow around it):
Is there a way to get this effect either through the GUI or programatically? You mentioned that the prototype had certain material level controls. Do you have any pointers on which controls these were? I am working anyways with the ParaView C++ API to create my objects, so if there is an API for creating this glow effect, I would love to hear it.
