Some simple geometric fractals

February 9, 2013 by Andy Brummer Leave a Comment

These guys use four transformations with simple rotation parameters.  All I changed is the scaling factor of the two central transformations and their centers.  It shows how the nature and feeling of the image can change dramatically with just a few little parameter changes.

Fancy geometric fractal
Simple nearly symmetric
Diminishing the top scaling emphasizes the edges

Balance the top and bottom and move them closer together
Tightening the bottom and loosening the top looks completely different
moving the bottom transform up changes the overall shape

Experimental generative images

October 18, 2012 by Andy Brummer Leave a Comment

These are all simple images where I’m testing out a very simple set of rules. I’m using a modified lorentzian function to generate the colors near each line. The position and intensity of each line is determined by a tree like algorithm. I got a lot of different effects from playing with the colors and the height of each line. Like many things in this learning process, I never thought some of these minor tweaks would have such a large impact on the resulting image. The parameters that I did expect to change things just ended up making things either too muddy, dense or too sparse. I’ve still got to give it some try with some real colors, but I’ve gotten sidetracked yet again!

HTML5 color eyedropper

May 17, 2012 by Andy Brummer 1 Comment

This is an uber-simple html5 eye dropper tool that creates a json array of rgba values. It’s the format I like to use for my demos and while I have a few colorpickers installed in my browsers there wasn’t one that let me pick a bunch of colors quickly from one image and get them in the format I needed. With some quick hacking I was able to put this together in about 50 lines of Javascript. Hopefully this leads to some more color full demos in the future.
