Voronoi Cloud Studies

[cyphyr]

I've been playing about with various methods of manipulating cloud layers with voronoi functions. What d'ya recon?

I wouldn't recommend it; using voronoi (or any functions, for that matter) on clouds really ramps up the render times.

Yep sure dose, these rendered between 1 and 4 hours each

nice effects, though. TGD/TGC for the first and third??

[old_blaggard]

For some reason the images didn't load when I made my first reply, so sorry about that.  The first and third look quite cool, and the last looks kind of like an abstract painting.

I like all of them.....

first and third are awesome

second looks like mammoth clouds (only if they were bigger)

last one looks like storms coming....

I tried that ages ago, but I could never be bothered to render the whole scene. Props to you on having the patience to see it through!

Great work Richard! First and third looks very very good!
Mind to share some tips or node-screenshots?

Thanks guys. I actually started out trying to get some sort of "Mammatus" cloud effect, nearly got there and then got tangented off in new directions. Its rendering a sweeter version of the fourth image atm with much higher settings. Thought it would be done by now but its still trugging away, about 3/4 way through. I'll post some clip files when I'm done but they are all basically different flavors of the same thing. A Power Fractal set to a low octave is plugged into the input of a Voronoi 3D Diff Scalar and the result plugged into the density shader of a Cumulus Layer. Adding a Colour Adjust before and after the Voronoi 3D Diff Scalar adds to the effect further. I'm sure there would be other ways of manipulating the shapes but I'm still getting to grips with the functions. What I'm trying to understand now is how to effectively mask the cloud layers so I can combine several different sorts of cloud effects together.

Very fun.  Looks otherworldly, which clouds can do from time to time around here even.

AWESOME! especially 1 and 3. These are effects I want. Higher render times are absolutely worth it.

[cyphyr]

Here's another go at the "Storm Clouds" and the TGO files so you can have a go yourself. The parameters that seem to be controlling what is happening are the various Scale settings. Try to keep them "real world" as much as possible.

Enjoy

love the rays man....very nice...and thanx for the tgds'

/edit

wow....I am surprised that you dont need any "get" function......

Hi,
nice experiments,like them all and thanks for the tgds.

[Harvey Birdman]

Those are cool! Thanks for the .tgd's. (And hey! What with the render time improvements in the latest release(s), this is more and more attractive.)
