Diffusion-limited aggregation

DLA can be observed in many systems such as electrodeposition, Hele-Shaw flow, mineral deposits, and dielectric breakdown.

Some variations are also observed depending on the geometry of the growth, whether it be from a single point radially outward or from a plane or line for example.

Brownian trees are mathematical models of dendritic structures associated with the physical process known as diffusion-limited aggregation.

The resulting tree can have many different shapes, depending on principally three factors: Particle color can change between iterations, giving interesting effects.

Simutils, part of the toxiclibs open source library for the Java programming language developed by Karsten Schmidt, allows users to apply the DLA process to pre-defined guidelines or curves in the simulation space and via various other parameters dynamically direct the growth of 3D forms.
