First proposed in 1968 by the biologist Aristid Lindenmayer (hence Lindenmayer system), an Lsystem is the name given to a type of formal grammar used to model the development of biological
structures. In more recent years, the usage of L-systems was extended to the field of computer
science by Przemyslaw Prusinkiewicz in the 1991 book “The Algorithmic Beauty of Plants” - featuring
a technique for image synthesis realistic of plant models. Further to the realistic modelling of plants,
L-systems can also be used to procedurally render self-similar fractal images.
Essentially, the main concept behind L-systems is the process of string rewriting. This means being
able to define complex structures by iteratively substituting parts of a simple structure, using a set of
pre-defined rules. This can be extended to image synthesis by simply applying geometric
interpretations to each rule.
