"Influenced by the work of D'Arcy Thompson, Alan Turing and Ernst Haeckel, the Aggregation series examine how the forms of intricate organic structures can be created by digital simulation of flow and deposition. Sculptural shapes are created by a process of accretion over time, gradually grown by simulating the paths of millions of particles randomly flowing in a fluid field. Over time they build on top of an initial simple seed surface to produce structures of immense complexity. The base algorithms used to generate images are variations on Diffusion Limited Aggregation, with different structures produced by introducing biases and changes to rules for particle emission, motion and deposition. The growth like nature of the process, repeatedly aggregating on top of the currently deposited system, produces reinforcement of deviations caused by small forces applied to the undeposited particles as they randomly move. The final rendered structures are implicit surfaces typically composed of 20,000,000 to over 90,000,000 particles. Simulations can run from many days to weeks. All the software used to simulate the structures and render the final images was written by the artist in Visual C++. "
