L-systems, or Lindenmayer systems, are a mathematical formalism used to model the growth processes of plants and other organisms through the use of string rewriting. This system uses a set of production rules to iteratively replace parts of a string, allowing for the generation of complex structures such as trees, leaves, and flowers in computer graphics. L-systems provide a powerful way to simulate natural forms and create detailed environments in CGI, emphasizing how organic shapes can be derived from simple rules.
congrats on reading the definition of l-systems. now let's actually learn it.
