Hello...
Sorry for beeing so late : we encountered a news client problem, here...
what you suggest (animating separately a lot of particles)
can definitely be done, but I should then animate small blobs of 'smoke"
embedded into a foggy medium, starting maybe with a spiral distribution.
But I am afraid of the rendering time. I am -as anybody after the
checkered floor
phase- trying to render
the "best naturally looking high resolution earth from space", and came
to
something I like, with a rendering time in the 30 minutes range on my
K6-233,
if I remember well... Then I decided to add the atmosphere, with
Rayleigh
diffusion, and the time expanded immediately to 2h30. So, I am cautious
about playing with media/interior/scattering and so on...
That is why my "black hole environment" is a texture, not a 3D object, I
confess...
But maybe I am wrong. Someday I shall try that for a galaxy, with a few
thousands
of individual stars; just for fun; just for a few minutes, maybe...
