This technique allows for the generation of many different natural looking patterns using random walkers. The technique is described in great details in an article on my blog.
- Walking step: a walker moves by a discrete step and has some chances to turn by a discrete angle.
- Deposit step: by moving, the walker leaves some substrate in the environment
- Division step: a walker has some chances to replicate itself, with only a variation in its angle
- Termination step: if a walker runs into some aggregated substrate, it dies
