Resynthesizer

Is there a tutorial for how to use the Resynthesizer plugin to make crop circles, like the images lylejk showed in this thread?
I'm trying to superimpose the Ubuntu logo crop-circle style on the famed "Bliss" wallpaper for XP à la this image. But I want it to look a bit more natural.

Just as a refresher, the "Bliss" picture (here) is the standard desktop image that first appears (appeared?) on a fresh install of Windows XP. Wikipedia has an article about it.

Including the target that I used and also note the adjustment that I made with the Ubuntu logo in the XCF file. This adjustment (minus the blur; figure you can guess what the logo would be like without the blur; lol) was what I also used before running Resynthesizer. What you need to create a grassy version is to find a crop circle match for the grass. I never could by the way and gave up back then. lol

Cool idea...! Here's something I started with...I probably would have spent more time on the shadow, but I figured I'd be here all night if I let myself.

Check the XCF to see the layers.

Pretty cool, Alex. I tried to make my own seamless wheat picture and never did get it how I wanted. I like Lyle's result, too. Although I'd prefer the flattened wheat to follow one direction.

Yeah; wish I knew a way to coax Resynthesizer to create swirled flattened hay, but I gave up on that dream long ago Mahvin.

edit:

Just realize that you are actually wanting to understand how to use Resynthesizer to create crop circles. What you do is open the grass target that I attached, and also your image that you want coverted to a crop circle. Make sure your image is flattened (since the target that I attached is flattened (in this case with black background since that will have the non-flattened grass); Resynthesizer wants both source and target to be the same w.r.t. this and also colors (i.e, greyscale or color). Anyway, see the picture below for what you are looking for.

Hey Mahvin; tried a blend of whirl/pinch blended in. What do you think?

Now you're talkin' Lyle! I used a radial blur, threshold, and applied a layer mode to the resulting layer. Maybe a whirl/pinch was a better thought.

Seriously, a little tweaking and I think you've got a very awesome effect here.

Awesome! Lyle, you are the best! You just keep on being that lazy filter guy. Keep presentin' for us GIMPers.

Lyle, can I get a copy of your seamless wheat image/pattern? Thanks!

It's not seamless Mahvin; that's the beauty of Resynthesizer. Had already included a lower rez XCF file (which is what I actually use; the higher rez original is not as useful), but I'll attach my original highest rez here. I usually resize it down to 200px width.

Need to share with you another trick. Once you create your white circle on black background, dup, lower opacity to 50% and then set to darken (top layer) then manually shift if down at 315° (well, I usally eyeball it) and shift to taste. Flatten and blur (default 5 px) since you don't want too sharp of edge transition, and use this as your target. I did the same for my Diablo version by the way. This gives you the inner edge when using the wheat target.

Thanks, Lyle!

Thanks so much, will try it out soon as I get a chance!

thanx very much for this "script" :-D. Now I will try to look for grass texture which match the flattened one

I posted the layered XCF here hanciong; you use this as target/mask combo).

oohh thank yoouu
