grammarGrowth grammars are a rule-based approach to the modelling of dynamic systems. In contrast to conventional imperative programming languages, rule-based approaches provide a natural and concise way of modelling. Most systems to be modeled behave according to a set of rules, and our perception works this way and not imperatively using a list of operations which have to be processed step by step.

GroIMPThis site provides software for the execution of growth grammar programmes. GROGRA is an L-system interpreter, GroIMP is an interactive modelling platform and able to execute programmes written in XL (a Java-based growth grammar language), XL4C4D is an XL-plugin for CINEMA 4D.
