This is a tumblelog, kinda like a blog but with short-form, mixed-media posts with stuff I like. Scroll down a bit to start reading, or a bit more to read more about me.
I’m in the process of streamlining my online presence, returning to longform blogging, consolidating my digital sketches and photography and finalising my web portfolio.
I’ve started updating my cargo page with more recent content (recent being < 12 months old) ha.
RTBP System demo #1
Screen from a real time particle system i have been working on in processing. The input sound is grouped into a specific number of frequency bands, each frequency band is linked to a point on the circumference of the circle. The density of lines emitted from each particle indicates the strength of that frequency through the duration of the song.
I’ll post a working build of the system with the song I wrote to test it eventually.
3D render of a Rossler system, I built it in processing and rendered it in blender. Sketch source code is available on openProcessing, but might be buggy on windows. (I need to replace it with a non-opengl version)

I decided to try and make a simple L-System in processing today, it turned out not half bad. For those wondering what I am talking about, im sure our willing friend ‘google’ can be of help.
My system works by generating a point in space, then using a L-system generated pattern to apply one of 8 transformations to the point, the transformations are:
As the transformations are applied, new points are created, each new point is joined to the previous point by a bezier curve of a set length.
My L-system is currently based on the fibonacci set of numbers, in summary the program iterates through the fibonacci sequence, generating a pattern of numbers that lie somewhere between 0 and 8 (I choose 8 as i only defined 8 transformations) to a set level that i specified (the length of the pattern). A parser then works through each number in the pattern, applying the transformation and drawing the new point and line.
To make it a bit more interesting, I decided to apply 3 rotation matrices to each new point (90 degrees, 180 degrees, 270 degrees) that is created, this in essence is like splitting the screen in to 4 quadrants and drawing the point in its equivalent place in each quadrant space. This all worked well, but I was getting the same results every time.
Computers are brilliant at crunching through numbers and conducting repetitive tasks accurately and quickly, so i decided to make a few of the initial variables random. With a simple click of the mouse button my sketch is completey redraw with a new set of parameters.
The image above is one particular configuration that I liked. This image uses a pattern that is 175 characters long, it uses only 4 of the 8 transformations i defined and it only rotates across 3 sectors (0 degrees, 120 degrees and 240 degrees).
More of this to come no doubt.
