Auto-Generated Images via Simulated Reaction-Diffusion Reactions+Tim Hutton
is a talented programmer with a range of private programming interests in addition to his employment by Microsoft as a Computer Vision expert. His recent post https://plus.google.com/u/0/110214848059767137292/posts/SqaTHbRjeve
announcing the latest release of software called Ready,
which is available on GitHub here https://github.com/GollyGang/ready/releases
served as inspiration for this post. Ready explores a wide range of different reaction-diffusion systems (https://en.wikipedia.org/wiki/Reaction%E2%80%93diffusion_system
) and seems inspired by Alan Turing's 1952 paper The Chemical Basis of Morphogenesis
- Ready's documentation includes details of the history of reaction-diffusion.
I thought the conversion of the image into a reaction-diffusion pattern that Tim showed was pretty cool and I wanted to make my own. After downloading the latest version of Ready and playing with the parameter_modulation_demos I used my two most recent profile pictures to make the images for this post. Two profile pics each subjected to two different reaction-diffusion transformations. After saving the images I adjusted the brightness / contrast in GIMP to get these final results.
But this is just one of the most trivial examples of what Ready is capable of. There is a whole library available to explore and I have spent about 2 - 3 hours now just lost in the different simulations. The Penrose Tiles, the Game of Life, the Game of Life on Penrose Tiles, smooth and organic Game of Life, other cellular automata, dividing cells, quantum wave functions, and many many others. And not just the preset functions of course, but playing with the parameters and seeing the effects on pattern evolution compared to the previous generation. Anyone with an inquisitive mind will get a kick out of tinkering with this and it might even inspire new and different ideas after seeing some of the patterns in action. +Samuel Holmes
