Voxel-based Geometries: Reaction-diffusion

Reaction-diffusion processes have gained increasing attention in the past years. Most experiments are focused on two-dimensional form, or on extruded time-based two-dimensional form. This project considers these processes in three-dimensional space: thus, rather than focus on pattern formation, it explores how these processes can enable spatial structures to emerge.

As in the subdivision experiments, the input to the process (in this case the initial state) is kept to an absolute minimum. It frequently consists of a divergent value in a single cell or in a line of cells. The process' parameters, in turn, are allowed to fluctuate in both time and space. This can include specification of parameters through spatial gradients, as well as the use of emitters and vacuums.

Changes to these parameters lead to a truly astounding range of structures. Yet the process is very difficult to control in that the output is hard to predict. A miniscule change in parameters leads to the formation of an entirely different structure, or it can prohibit a structure from forming at all. A deliberate, constructive use of these processes on an architectural level appears a long way off.
