While we all quarrel about which program creates the most realist clouds, Nature is busy at work.

Today I saw an article about Asperatus clouds; it contained a picture so unbelievable that it could not have been photoshopped.

I found an interesting cloud images reference site The Cloud appreciation Society and in their gallery there is a section specialized for  this kind of clouds. I find this example the most impressive.

Bye!!!

If someone would do that in Vue, everyone would say "very unrealistic". :-)

Wow, weirdest cloud I've seen. So unrealistic! I suggest the guy who rendered this go, and and look how real clouds look like -)

Hey did you see that on the BBC site?:) I jsut posted about it on a game forum!! ;)

think this is my fave...
saw one like this here, a few years ago, except it was more like looking up into boiling, molten copper...scared folk, seriously, was so eerie!

Nothing to say except that nature is still the greatest renderer existing today. And it does all of this in real time!

Thanks for the link, Alex. I wonder if those type of clouds were in any way responsible for any of Van Gogh's work?

Thanks for the links. Very impressive and inspiring shots, especially the "asperatus" clouds.

 

I had to give it a try and came up with the picture below (grainy, low quality render)

Those are Spectral II clouds. I bypassed most of the regular cloud model parameters and built a "cloud model" in the function editor. The main challenge was to create distortions on Z. The Spectral II model allows "altitude variations" but it won`t allow actual distortions in the z direction.

It`s not perfect but at least it shows some of the potential when using the function editor along with the  Spectral II clouds model.

 Another try (still grainy). Took considerably longer to render because one of the nodes is a Terrain Fractal. (See screenshot below)

The Gaussian Tooth node (wavelength 0/0/1) to the right generates a layer within the main layer, which then can be distorted in all 3 dimensions. Rather crazy approach, but it works :-)

I reckon Van Gogh was looking through the bathroom window at the time :)
