Computational reaction-diffusion systems mimic chemical pattern formation in nature. A mixture of two or more chemicals that react with each other and have different diffusion rates forms macroscopic patterns in time and space of chemical concentration. The chemical mixture stays in a continual flux and therefore far from equilibrium.

Alan Turing was the first one who proposed reaction-diffusion systems as a theoretical idea to explain biological morphogenesis. It demonstrates how breaking and pattern formation can arise out of a homogeneous, uniform state.

The Belousov-Zhabotinsky reaction is a special non-equilibrium system that works as a chemical oscillator as it cycles through its different states in autocatalytic fashion. If unmixed the diffusing chemicals spread and cause spirals to emerge and grow.

Stills taken from a serie of videos in progress that I have entitled "Activated Memory". I'm using photographs that I take of Montreal parcs and houses and I animate them in order to create enclosed gardens and artificial environments.



I made this film in 1979-80 to accompany a SIGGRAPH paper on how to synthesize fractal geometry with a computer. It is the world's first fractal movie. It utilizes 8-10 different fractal generating algorithms. I used an antialiased version of this software to create the fractal planet in the Genesis Sequence of Star Trek 2, the Wrath of Khan. These frames were computed on a VAX-11/780 at about 20-40 minutes each.

Video for Le Révélateur

Age Maze along with Bleu Nuit and Mirages will be released on DVD this October by the San Francisco label Root Strata.
