GBoGBo's random stuff

Cool.Have you already written a short tut on that?

Yep Knacki !


This is actually a (attempt) remake from scratch of Robert Bosch's Embrace that blowed my mind when i saw it last week:
http://www.bridgesmathart.org/art-exhib ... bosch.html

It is an example of so called "TSP art" (art constructed by solving instances of the Traveling Salesman Problem) with a playout on Verve (and a bit of photoshop color shift on selections).

I did not tire myself a lot because i found all the necessary tools off-the-shelve (freewares) : I used StippleGen2 to generate a stippled image of the celtic disc image that I found on the internet, then Concorde to get the precious closed TSP path (StippleGen2 could not achieve a closed path), then Processing (as usual !) to move the mouse pointer above Verve according to the path.

Input Image (celtic pattern):


StippleGen2 :

Output image:


Concorde :

Concorde treated the points of the above stippling image as the cities of a Traveling Salesman Problem.

And some useful tools for converting files from/to these different programs :

There is a demo without time limit but without save AI, SVG !
But you can save your work in program format!

That's so fascinating, Gbo, crazy! I'd almost want to see this played out with a little bit of fluidity, maybe no curl...lot's of fluid smudge or some other setting... could be fascinating, too... or totally silly, who knows.

Thanks Pilou for the tool to make my own knots, and Taron for kind interest !
-> With more liquity (and painting instead of erasing) the path is melting with itself :

I don't know...

[Taron]

Make it metallic and color it properly and it will look like an ancient artifact salvaged out of a sunken ship!

Yep, ancient metal was my first idea actually ! but i was not happy with the results -> i may give another try !
By the way I tried also the FLUID: CURLS 0% as you suggested and i like the output very much, it's like ink printed on the wrong paper :

[Taron]

Yeah, like a worn stamp of sorts. Interesting! Have you turned fluid sharpness to 0%, too? Should be a bit different?!
I also wonder what it would...oh, man, there are so many possibilities...nevermind. ...it's just cool!

Very cool - just can repeat myself. And many thanks for all the links

Thanks Knacki, you're welcome.
By the way software-versed guys and gals, i always put my Processing sketches on-line, feel free to have a glance (or even use it - if you can, because it's a bit messy...) :
