Here's a class for SuperCollider that generates perlin noise. I wrote it about a year ago to learn how that works but didn't finish the help file until now.

Some examples of images made with this class...

and this is an example from the help file that gives an overview of some settings of 'persistence vs octaves'. The 8 steps of persistence grow from 0.25 to 0.95 left to right. And octaves grows from 2 to 9 bottom to top.

Sorry, this place got hacked and someone overwrote all my media files (snd, pic, vid). I'm travelling atm and it will be a few more weeks until I can access the backup files and restore the archive.


LOSS Livecode History from the Pub

2007-07-24 18:32 livecoding

Here I've attached the SuperCollider history file from my performance at the headphones concert at the live coding festival in Sheffield... livecode.access-space.org (archive.org)

It's a bit embarrassing if you study it more carefully. The use of ~pub near the end is a big mistake for instance. I meant ~out and I don't know what I was thinking there...

You can also look at the file '2007-20-20pub.rtf' for the actual document I used. Some comments in there didn't make it to the history file as I forgot to evaluate them.

Here are also the notes and statistics from my presentation "Live coding practice" in which I talked about my month worth of practising.


June Practice Sessions

2007-06-10 16:28 livecoding

In preparation for the LOSS livecode festival (archive.org) in Sheffield, I'm doing another month of practice. 1 hour/day, start with an empty document, no third-party classes or UGens and then upload the result here on the swiki.

This time my sparring partner is photographer and artist www.fotokatie.com/katier. She's doing a very nice series of 'star shots'.

In addition to getting my live coding chops in shape (hopefully), I got commissioned to analyse and present the outcome at the festival. This is a great thing. So the bet with Katier provides the pressure, the scheduled talk the deadline for analysis, the upcoming gig the motivation and last the commission pays for one strong coffee at my favourite café each day of the period. What could go wrong?

Well, it's summer and I've been working too much as is...

Low Life

Attached are three programs that all use some sort of audiovisual self-referential code in that they synthesise their own syntax.

As I think this only works on SuperCollider OSX I made some short videos...

One can also write custom 'scores' for these programs to perform...

Note: will only run under older SuperCollider, version <=3.6 with OSX (Cocoa).

Two photographers that have witnessed our gigs have put up some very nice photos on flickr. See Munich and Brisbane. Pretty funny comments there too.

August Practice Sessions - Again

2007-04-12 22:28 livecoding

Nick has written a nice paper on live coding practice (for NIME 2007). He discusses some of the issues discovered while doing the practising pact last August.

A different plot for SuperCollider. Though it is actually more useful as an 'artistic' visualiser rather than a serious way to represent data. It works with collections like arrays, envelopes and wavetables. The technique is to translate them to length/angle pairs and then draw a shape from that.

It's distributed via SuperCollider's package system quarks. All open source.

//and then recompile

There's also some older code here that does similar drawings...



And of course, it's always more fun when things break. Here the same thing with a nice bug...
