Here's 2 work-in-progress images for the "fire & ice" IRTC topic, I don't
think I'll have time to finish both, so I want an honest opinion on which is
better.
I have a slight preference for one but I'm not going to tell you :)
The first image is a comet (in the top left, near the sun) trailing icy
fragments which are going to fall to earth and burn up in the atmosphere.
Obviously this scene hasn't got the comet-tail effect, and the distant
fragments aren't burning up, so this one requires a bit of imagination...
The second should be self explanatory, but in case it's not obvious: a
snow-covered volcano erupts, the heat of the lava reshaping the cold
mountain, meanwhile beneath the sea lava slowly flows out of an underground
vent and solidifies almost immediately, the cold of the water reshaping the
hot lava.
So which would you rather see get finished?

I think the volcano image has great potential... Maybe easier to link to
the theme. And I'd really like to see a volcano done in POV :-)

Well so far I've spent several evenings - I guess maybe 10 hours work - on
the comet scene, but only 2 hours on the volcano. To be honest I think the
volcano image may turn out to be the simpler of the two, simply because
there's a lot less tweaking involved. I know what a volcano looks like but
what should meteors look like from above? how do I make the fragments look
icy? (actually I think I've figured that out now, but I must have spent 4-5
hours just tweaking the icy fragment effect). The point is the comet image
requires a mixture of imagination "what would it look like from this angle?"
and pandering to audience experience to make icy rocks that look like ice
does on earth, despite the environment around them being black...
Anyway I'm waffling, the point is I actually think the volcano's the easier
image, by a small margin.

Knowing what a volcano looks like will, IMO, make it harder to
realize. Everyone else does too and realistic fumes are hard to do.
Where as a space scene is only bound by your imagination. For these
reasons I would like to see your volcano :-)

I like this although i would leave out the comet idea and just go for
earth + some rock/ice fragments. The ice material is already quite
impressive - must be quite slow to render or did you use some fast fake
scattering technique?. The only thing that bothers me is the grainy
reflection spot on the earth.

Well that's the other problem I have with the comet scene, it's insanely
slow to render! I have media for the earth's atmosphere, there's media for
the comet's tail (turned off for this render to get it below 16 hours!) and
the icy rocks have refraction, reflection, fade_colour, AND scattering
media! So definitely not a cheap trick, more a ludicrously complex trick.
But I agree the result is very pleasing, definitely worth the effort.
That grainy reflection spot will go away at some point, the earth's textures
look terrible and are just placeholders.
I like the idea of throwing out the comet, my original idea didn't have a
comet and was just meteors, but I wanted to see if I could get more things
in the scene. Still if I remove the comet I can finish this scene in a lot
less time, so maybe I can do both images before the deadline... that's an
interesting thought...

In my experience this is less of a problem. The trouble is if I do the comet
image there's a big chance a lot of people won't understand what they're
looking at, which means I have to work on things until they use recognisable
elements, like my ice material. I don't think ice would actually look like
that in space, I've totally cheated with the lighting angle and internal
colours, but because it looks like ice on earth your brain tells you it's
ice and then you can interpret the scene with that information. I'd need to
put equal effort into making a flame effect that looks like recognisable
fire but also looks like a "shooting star". Whereas with a volcano you can
immediately see what it is, so perversely the tiny details are a lot less
important, and I can get away with very stylised effects provided the
overall impression is a volcano.
