I've created some brushes which use custom profiles based on Fibonacci numbers and the Golden Section. As a result they produce very naturalistic textures.

Adam says he'll post them at Satori Central soon - meanwhile anyone who wants them can email me directly for a 10kb zip file.

Hope you artistic types can make use of 'em.

Cheers,

Chokky.

I have added the brush set to Satori Central.

For any PhotoXL V2.29 users, this set works with V2.29.

I urge anyone who hasn't been to Satori Central recently to make sure you check out my Brushes page as there have been, in addition to this brush set, 2 other recent submissions including one more that will work on Satori V2.29.

Thanks. I really do appreciate all of the submissions I get for Satori Central.

Satori offers 2 solutions to this – the truly random, resolution independent Chalk brush and the Movie brush – each of which offers a different possible solution to the problem of pattern recognition through repetition.

Chokky now offers a possible 3rd way.

The employment of Fibonacci “organised” material in the brush profile gives rise to a kind of pattern (through repetition) that is both ubiquitous in nature and aesthetically pleasing. Turning a disadvantage to advantage as it were. I LOVE it!

They must have taken a lot of patience to construct. Did you trace them from an underlying drawing? Or something much more clever?

Thanks and thanks again, Michael

I opened them in Satori and then clicked once on each dot (with mouse) using Solid brush. Finally I deleted the original bitmap (leaving just my dots) and saved the file.

Took about 10 minutes.

Anyone with a couple of hours to burn could tryhttp://www.mcs.surrey.ac.uk/Personal/R.Knott/Fibonacci/seeds5000.gif

That one has 5000 seeds!

How did I make the brush so fast? There are two ways. The first is to use Luma keying and remove all of the white background and then invert the mask and save it as a .rir. That seems to be the best method. Or, you can use the magic wand to do the same.

I did it with Luma keying. I was able to use the resulting brush to paint using a 1099 pixel wide brush on a 6000 x 6000 pixel canvas and zoom in at 32x and hit the Hi-Rez button. And guess what? Nice clean edges. Now, the dots are actually different shapes in this instance. That may because of the way the original image was made or compressed or the way Satori did it's keying or magic wand action. But the point is that you can use Satori in many cases to create resolution independant patterns from resolution limited ones. The results depends on the quality and compression used on the original image and obviously there are limits to how much you want to go up in resolution because you are likely to see the small imperfections (unless of course that is what you want). But the results never have the jaggedness you would associate with typical upsampling.

Anyhow, take a look at the following link:

http://www3.sympatico.ca/adamy1/seeds.gif

This started off as a 6000 x 6000 pixel canvas with a 1099 pixel brush. I then cropped the canvas and saved as an .rir. I loaded that .rir and selected a small crop area in the center. I saved that crop area as an .rir reloaded it and used the web optimizer to make a .gif. A bit convoluted but I was just mucking about.

Very cool.

Adam.

I'll use your method for some other dot based images, maybe a chunk of a Seurat painting, just for fun.

This produced a random array of leaves which I saved 5 times - FibLeaves1.cvs, FibLeaves2.cvs, etc etc

Finally I made a new Movie brush that used FibLeaves* as profiles.

The result is wonderful - a super-fast, random foliage generator.
