I have wanted to do a similar image with CSG
for a long time now.

But when I had a peek at Rene Smellenbergh's
Isosurface Manual web pages (thank you Rene),
I realized that it could probably be done quite 
simply with an iso-surface.

In this image I used a modified version of 
one of the "blobbing" methods that he describes.

Any suggestion for this scene ?

    I did a very similar scene once and I tried two different tracks. One
was to give the impression of explosions in the background, as if the
technology that held it together was failing. The other was to use it as a
heatsink around a star.

    I never got the explosions to look good in a still. Unless they were
sharp and happened in a variety of places at random times (i.e. a very slow
rendering animation) the idea was not expressed. I think I posted it here as
a heatsink. Lots of media and shadows streaming out.

    I found them, the ones as a heatsink... hope they give you some ideas...
I scrunched them pretty badly.

Yes this reminded me of your work too Bill, didn't you enter it
into the IRTC?  I seem to remember it being a good image but 
totally off topic, maybe it was the Horror round last year?

?

Why would anyone build a heat sink around a star, for crying out loud?

    When you want the heat for something else, or when you don't want the
heat beyond the sink.

I think a large enough heat sink would cool down a star.
Of course, that would be a pretty big heat sink!

These are really great !

Thank you for sharing.


But how did you do the lights for the explosion ?

And did you use any media in there ?

    I did several lights of different color and different fade_power.

    Yes, a large, slight scattering if I remember correctly.

I on the contrary think the star might heat up more...
