Getting some interaction now using a media to form where the ring particles
interact with the asteroid.  Not great but it's an improvement.
This is the second part of 3 I have in mind for now, have yet to put all three
together.
Thinking I need to add some lights or radiosity to get the hot glow to
illuminate the surroundings.  Not looking forward to that.

I just thought, that the texture of the asteroid should change during
transit, because it would get more craters :-)

Concerning the ring, maybe some more variation in density and some less
sharp borders would be good.  It vould even be devided into several
smaller stripes.

No?  That's okay because like I had said before it will no doubt change again.

Ah yes, I haven't gotten to part 3 yet and that's where it will need that
happening.  I might not ever finish.

It's all random right now, from closely spaced to wider spaced rings.  Colors
are random too but start from a medium gray.
I haven't figured a way of going about it to get gaps in the same density blend
map.  I'll post here with the part 1 animation so you can see the ring better
from a distance.  Small mpeg file.

I know that feeling...

It looks really a bit to regular in both color and density.  I don't know
very much about media, so i can't help with that.  Some photos:

i see that the planet is rotating.
I assume the ring rotates too,
so as the rock goes through the ring,
it should leave a wake or trail in the ring.
perhaps you could add a media element attached to the
asteroid that interacts with the media in the ring object
downstream to create the effect.  Is that how you made the
glow?  I really like how the leading edge glows bright.
I imagine a particle method would
work best for accurately simulating the ring,
 but that would take years to render.
Looks very slick anyhow.

Thanks, yeah it is going to have some kind of downstream wake if I can manage
to add that.  CSG differencing away a hole didn't look good.
A close-up view of the interaction as it now is terrible too, you just don't
see it well in this yet.
It is a scaled up media-filled slice of the asteroid/ring intersection.  Pretty
simplistic except for the fact I have the scales, rotations and translations
all done first and yet the asteroid still passes through <0,0,0>.
One of those things that make me wish I could paint it in and not try to CSG my
way through.
Ring rotation is opposite direction of asteroid direction btw.
