Lindenmayer systems (or L-Systems) are a way of modelling plants and other biological organisms using mathematics and simple language tools. Lindenmayer Systems Artificial Life Computers.

- Wikipedia: An L-system or Lindenmayer system is a parallel rewriting system and a type of formal grammar. An L-system consists of an alphabet of symbols that can be used to make strings, a collection of production rules that expand each symbol into some larger string of symbols, an initial "axiom" string from which to begin construction, and a mechanism for translating the generated strings into geometric structures. L-systems were introduced and developed in 1968 by Aristid Lindenmayer, a Hungarian theoretical biologist and botanist at the University of Utrecht. Lindenmayer used L-systems to describe the behaviour of plant cells and to model the growth processes of plant development. L-systems have also been used to model the morphology of a variety of organisms and can be used to generate self-similar fractals such as iterated function systems.
- Digital morphogenesis - Digital morphogenesis is a type of generative art in which complex shape development, or morphogenesis, enabled by computation. This concept is applicable in many areas of design, art, architecture, and modeling.
- Fractal - In mathematics a fractal is an abstract object used to describe and simulate naturally occurring objects. Artificially created fractals commonly exhibit similar patterns at increasingly small scales. It is also known as expanding symmetry or evolving symmetry.
- Iterated function system - In mathematics, iterated function systems are a method of constructing fractals; the resulting fractals are often self-similar. IFS fractals are more related to set theory than fractal geometry. They were introduced in 1981.
- Hilbert curve - A Hilbert curve is a continuous fractal space-filling curve first described by the German mathematician David Hilbert in 1891, as a variant of the space-filling Peano curves discovered by Giuseppe Peano in 1890.
- Stochastic context-free grammar - Grammar theory to model symbol strings originated from work in computational linguistics aiming to understand the structure of natural languages.
- SpeedTree - SpeedTree is a group of vegetation programming and modeling software products developed and sold by Interactive Data Visualization, Inc. that generates virtual foliage for animations, architecture and in real time for video games and demanding real time simulations.
