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.

Well, I was going to say "volcano" because it looks more dramatic and
well-composed right off the bat, but then I looked at the comet picture up
close and boy- you really *have* that icy chunk texture! So I guess I would
still say volcano- although I think the underwater vent might be hard to do
without confusion- but it would really be cool to have those icerocks in
there somehow. (Maybe a comet hitting a volcano from high orbit? That's
like some terrible sci-fi schlock :))

Anyway, good luck whichever one you choose. I'm sure you're superbrain will
create a fine (if evil) image.

I was thinking the same thing, I'm really pleased with that ice material. 
Well the volcano has snow on it, and I'm making it a very wintery scene to 
play to the topic, so there's no reason I couldn't shove one of those lumps 
of ice in the foreground somehow.

In the end the choice is yours, of course... My personal impression is that
the volcano is somewhat too obvious. Everybody is going to think about
Iceland or Mount Erebus on Antarctica. So, I expect a large number of
volcanoes in this round. The comet, on the other hand is more challenging,
perhaps a little bit less obvious for the topic, but full of potential...
and difficulties.

As some sort of compromise, what about Io (Jupiter's moon) or an Io-like

My thoughts exactly. The volcano will be hard because lots of people will be 
doing that, but the comet is a harder subject to do well I think.

Still, most people have sided with my personal preference of the volcano. So 
I'm going to do that one and then try to leave enough time to finish the 
comet.

Ah, but there's 2 problems with that: There's not enough atmosphere around 
Io for the icy comet to catch fire, and there's no ice on the surface of Io 
(as far as I know). So really it loses the point of both images! Besides I'm 
not looking for a compromise, I think each image has enough in it already 
and trying to combine them will make it crowded and confusing (to be honest, 
I think the comet image already runs the risk of confusing people).

Thanks for the suggestion anyway, and feel free to correct me if I 
misinterpretted your suggestion :)

How about Io (fire) and Europa (ice)?  There's even a connection between the
two in that Io's fire is caused by the tidal tug-of-war with Europa and
Jupiter.

The suggestion was more or less that including Io in a space image
automatically included the fire, because of its vulcanos, and as
you had already started modelling them for the other image...

I also like the idea of Io and Europa, but that would leave no room
for your nice icy comet particles, so we leave that for someone else,
I guess.

Io and europa has more potential. The trouble with Io and a comet is they're 
2 completely independant bodies in space, that you've brought together for 
the topic. i.e. you've got one picture of fire, and one picture of ice, but 
nothing relating the 2. The main focus of both my images is some kind of 
interaction between the two extremes, particularly in the comet scene where 
the ice would actually cause fire when it burns up in the atmosphere.

But Io and Europa are interesting because they're 2 extremes orbitting the 
same planet. Still, I'm not going to try that one I've got too many ideas 
already!
