Just showing an example of cheated cloud "boiling", following on from this question:

Not the best quality, but should give an idea. See the topic above for how it was done.

Nope. Galileo was right for the simpler reason that he was right.

very very nice....I love the animation....

That looks quite convincing :).  Nice job.

Looks good. Similar to a number of such tests I've done before, but regrettably never shared. My long-in-progress St. Helens animation project is actually going to include some cloud animation like this, although with the camera moving as well it may be too subtle to see without really looking for it...

So do you have bigger plans for this? Is it going to be incorporated into a larger animation in TG2, or just used a backdrop, or is it just for experimentation?

Wow, Jim, great job.  This is very cool.
So this is Disney World.  Can we live here?

It looks nice...

How long was the rendertime for this and how many cloud sample you are use?

Thanks for the positive comments everyone.

@ Oshyan; it's to have my options open for future jobs that require slight boiling in clouds. I recently bought Ozone for XSI to have internal atmospherics, but I have to say the actual look of the clouds themselves falls very far short of TG2's. However, the boiling in Ozone is very sweet indeed, and I suggest it be looked at by you guys as a kind of 'target'. I'd suggest having it present in your Mt. St. Helens project just for that little 'something extra', but only very subtle. My test is too extreme, but I wanted to see what was going on when the two transforms where mixed.

@ Gastar; as usual render times are high, about 25 minutes per frame at 1024 wide, but the quality is up quite a bit so no surprises at all. The proper frames are much better to look at, but I tried to keep the mpeg conversion low in size for the forum to download.

I anticipate render times being significantly lower (even half is fine) when the optimised version is released.

Considering this is the first attempt I have to say I'm very pleased so far. My main comments (as a client) would be the edges have gone softer compared to a single fractal animation (I'll look into that), and where both transformed fractals don't intersect you can just about spot the Y direction of the transform, up or down. But the overall effect tends to negate that impression, and only the most demanding and critical of clients would demand that be fixed I suspect.

I'll post any more versions I get around to doing.

One important note is you should use Ambient Occlusion, not Final Gathering, to avoid flashing.

hey, thats pretty noice, photorealistic. One thing i tought i saw was that some of the clouds were moving in different directions, which if thats the case is not very realistic; but as I said, good job (;

That looks pretty cool, good work! :)
Nice to see an animation posted here.

Another test, this time increasing the warp of the fractal over time, and translating it in the X as well (no Y translate - all boiling is down to the warp). Very pleased.

Ignore the fizzing in the shadows, the clouds had a lower quality setting, as well as the atmosphere. I also had to compress it a fair bit to upload here.

now that is awesome; very, very real (;

Wow that's really cool!
I'd love to see that @ high res. Would you like to upload it at rapidshare, megaupload or whatever?
