These are great. I'm totally going to be using some in UDK, eventually. I'll bump the thread when I have something to show.

What's UDK again? A 3D engine for a game or rendering/modelling tool? Would be awesome to see what you do with them, no matter what you do :)

also, another 1536x900 one, last one for tonight:

BTW the big rectangular images also tile, except rectangularly, so that might not be very useful for textures (unless you rescale, but then the aspect ratio changes, which may or may not be a problem cause they're quite random patterns anyway and you'd just get a sort of directional preference)

Can you do the last one 2000x3000px? If you can I can drip P3nT's awesome creation juice all over it :ninja:

UDK is the Unreal3 Engine's "free version", so a game engine... I've been working with code for a few weeks now (non-UDK), but I need to get back to my lighting, texturing, and environment art in that engine...

Thanks Trip!

my poor little netbook is going to croak, but I'll try and see if I can run that over the night or something :)

to give you a rough idea what it will have to do:

- fill the 2000x3000 with random noise
- duplicate that into 14 layers
- apply a different Gaussian Blur to each layer with radiuses varying from about 2.3 up to 72.
- subtract the layers in a clever way and make the pixel brighter or darker depending on whether the smallest difference is positive or negative
- repeat the above duplicate/blur/subtract sequence about 30 times.

now your computer is prolly all fast and would do that shit for breakfast :) mine's gonna need a night for it, though :) :)

it's the blurs that soak up most of the time and fortunately there's some ways to get a pretty good almost-gaussian blur much much faster, but we haven't made it yet (it works by applying a box-blur, which is ultra-fast, three times or so, and it's nearly gaussian).

sorry P3NT, but early this morning I woke up to an out-of-memory error during the very first iteration.

Don't sweat it I'll try make do with upscaling the original. Planning on overpainting the shit out of it anyway so a bit of blur won't be the end of the world

ok, upscaling would look different than what I'd have generated as well. cause the blobs and bits would have stayed the same size, there'd just be more of them.

and once more, they all tile. If you fudge it a bit so the tiled parts are on the edges, who's gonna know :) ["offset filter" in PS, afaik. basically just does sliding things around while wrapping, also very useful for making your own seamless tiles]

really curious what you're going to do with these :)

BTW all images are made from two layers, one with the colours and one greyscale for the brightness which is multiplied on top of it. In case it'd be useful I could get you both separate.

I don't really think it'll matter. This is like tracing paper with built in tripping balls. And the fucking thing NEVER REPEATS!!!! All I have to do is spend a couple of minutes staring at a bit of it until I see something jump out. Like staring at clouds.

checkit - when finished (in about seven or eight hundred years!) it will be 80-90% overpaint

OH FUCK!!! YOu'RE GONNA PAINT GEIGER ALIENS AND ZALGO INTO IT

SHIT YEAH :D :D :D ( <-- that's actually one grin but mine's 3x as big as the single emote )

that's so awesome, if you need anything, just holler :) for example as you can see on the prev page in the avatar animation, I can sort of "seed" the pattern to respond to a certain shape (notice how the lines and blobs kinda follow she shapes of my face). although I understand that's the wrong way around, you take the randomness and be inspired by it.

I do agree, I personally love that technique as well and as you mention it, these weird-ass organic shapes are quite perfect for it.

A bit like when I made this other random doodle generator and Cram painted/WOMPed goatseman into it :lol:
