Hi Pilou !



Code + Verve + Photoshop

very nice flower ... what kind of code?

Hi Zero, thanks for your interest. It is very serendipidesque as you will see :

1) The code is rather simple, it is an adaption for Processing and mouse Robot of the "superellipse" formula, the initial code is in p5.js from Dan Shiffman :
https://en.wikipedia.org/wiki/Superellipse
https://www.youtube.com/watch?v=z86cx2A4_3E
Here is my code : http://www.gbotet.fr/vrv16/P/superellipseV.pde
I limited the shape evolution from the initlal cross to parabolas to the circle. First I obtained this on Verve, a bit disappointing :


2) Then with the exact same code, i used a larger brush #9 with negative bias, and the famous "feather" setting from Borhani (works well on Verve2014), and i got this superb colored shapes (random color variation by pressing N), nicely separated in 4 groups thanks to the smooth evolution from the initial black cross :


3) Now the photoshop part :
Image->Adjustements->Invert :

Filter->Distort->Polar Coordinates->Polar to Rectangular :

Image->Image Rotation -> 180° :

Filter->Distort->Polar Coordinates->Rectangular to Polar :


rgds,

Another try, without Invert this time but with some Hue/Saturation adjustements. It's looks like a succulent.

Yes it does indeed Gbo. These coding experiments are a continuous source of fun. Its always interesting to see what you come up with!

Thanks a lot Tartan

That is always beautiful but seems use of code is "superfétatoire" !
Painting in symetry must make the same!
But i understand the pleasure of coding and research!

Ps You are uptodate because the super ellipse is the last opus of Daniel Shiffmann!
I show all his videos days after days! It's fantastic to see imagination and apllication in real time!
This guy is a phenomenon!

I agree with you Pilou that using code (rather than hand) was overkill here, but i am obsessed by the near-repeatability aspect of drawings, especially when fluids are unleashed. I enjoy the process of being able to produce similar drawings by dozens and choose the "fittest" among them. And I agree also about Shiffman, excellent teacher on Processing and now on p5.js !

I can really relate to the joy of your experiments! It only makes me angry that I haven't got this level (or any level) of scripting for Verve, yet. It's- naturally- highly inspiring!!!
Maybe you can imagine what influence you are having on my thought processes!
