Spelunking

June 13th, 2011

An animated exploration of a particular space-folding equation space; the whole is mathematically derived and driven.

The soundtrack is a small scoring exercise I composed and recorded some years back and chose to use here for flavoring.

Ghosts

April 13th, 2011

A few earlier posts (δυναμικός, Explorations and Exploring Entropy) have shown the result of some of my animation work with making short films of the evolution of time-discrete phase planes. Those animations are the work of hundreds, sometimes thousands, of individual frames. I thought I’d offer a little something different this time, so here we have a video showing how a single frame is drawn. It is set against the background of the Nine Inch Nails‘ track “9 Ghosts I”, which, along with the day, inspired the title.

The process of illustrating a dynamical system

δυναμικός

Years ago, in Dr. Pickover’s book Computers, Pattern, Chaos and Beauty, I first encountered the idea of plotting time-discrete phase planes. In the time since, I’ve often explored these for various functions, whether still images or animations. Most of the animated work has remained unreleased due to considerations of size: most video compression options overly distort the images due to the dust-like nature of much of this material, reducing the quality. But for the sake of example, and potential curiosity, I’ve decided to post one of the short films. The quality isn’t ideal, so bear with it, but it strikes the best possible balance between the intended quality and a filesize suitable for streaming over the web; perhaps as bandwidth increases and codecs improve, I will eventually be able to share the original, full resolution versions.

The individual frames were calculated with perl, rendered with GD, while the audio was produced with cSound, compressed with LAME and the two mixed with mencoder.

The audio is called “Moving Grey” part I, and comes courtesy of Andreas Bjorck.
