The Koch Curve Fractal

Thursday, August 21st, 2008

Yesterday in the KKB211 lecture, we briefly went over fractals, in particular the Koch Curve fractal which is probably one of the more well known fractals along with the mandelbrot (Benoit Mandelbrot coined the term fractal).

For anyone that doesn’t know what a fractal is, it is effectively a geometric image that repeats itself infinitely no matter how far in you zoom. They are usually irregular appearing images, but they are “self-similar”.

The koch is a snowflake star shape and is one of the earliest fractal shapes to be recognised.

For an interesting look at how it replicates as you zoom in and how self-similar it is, have a look at the Java applet over at ArcyTech.

Walking Lines 3 – Processing

Thursday, August 21st, 2008

Walking Lines 3, joining lines.I received some feedback on my earlier versions of the walking lines in the form of a trackback from Alex.

The feedback was part of a practice peer review, but he went into some detail on how i could fix up my current code so that the lines follow on from each other and how to reduce the load on the CPU per cycle with the same effect. The advice is greatly appreciated.

View the new version online here.

The changes and source code are after the jump.


Fractals and Influences

Tuesday, August 12th, 2008

Fractals have always particularly appealed to me. They seem chaotic and yet orderly. I actually focussed on this concept in year 12 for my major art work which was selected to be featured in 5 galleries across NSW.

One of my fractals

If you look at my Deviant Art account at all, you’ll notice that it is absolutely full of fractal stills. I also had some big A1 and A2 fractal prints on exhibition, as well as an animation, at a recent inter-university festival between QUT and UQ. So I can easily say that fractals are definitely where my love in art is at. Since I first began experimenting with fractals, there has been one particularly big influence in my work, and that has been the work of Scott Draves aka Spot.

Spot’s work has been of interest to me basically since I began working with fractals and it continues to do so.

He has done a lot of work in fractals and started the Flam3, Electric Sheep and Dreams in High Fidelity projects, all of which are quite influential on my work, both in fractals and in other computational arts.

Not all of his work has been focused on fractals, but many of his idea’s share similarities with them. One example of this are his Dub Visuals which take chaotic still images and morph them, to form other still images in a flow similar to that of the evolution of his fractal animations.

I have previously done fractal animations where they are synced with music, both music performed by another artist and music that I have composed myself. However, this hasn’t been done in real time and has been a long process to setup each portion of the animation and sync it up with the music. Ultimately, I would love to develop a way of rendering fractals, even low quality or low resolution fractals in real-time based on audio input. Basically this would be combining the work I have done previously with the basic concepts of what I did for KKB210 where I did a series of lines and boxes that responded to audio input. The lines one was probably getting close, though ultimately no where near as detailed as I would like it to be, and definitely nowhere near as chaotic and fractal-like as I want.

That is my aim though and hopefully I will get to it sooner or later.

Walking Lines 2

Monday, August 4th, 2008

Walking lines 2Continuing on from the original walking lines I did in Processing, I went on to develop this version of it. This is done effectively the same way as the original, but the code is cleaner and it provides for more variation. It also runs slower.

This version should allow further development to make the lines even more random by separating all the variables, where the original was more limited since the numbers were largely defined within the line parameters.

This version is also technically more stochastic then the first one as well as the lines are added to and built on using the += command to add the new line position to the previous line position. Unfortunately this still draws a new line every frame that is not necessarily joined to the line from the previous frame.
