Learning about a new field is often accompanied by a lot of new acronyms/terms that seems to be perfectly clear for anybody else. Plant modelling in GroIMP is no exception from this. Therefore we want to provide you with a small overview of the most commonly used once.

functional structual plant modelling.

FSPM is the main field of application for GroIMP and describes the aim of simulating the spacial/geometrical appearances and the functions of a plant simultaneously.

Lindenmayer system

Lindenmayer systems are a group rewriting grammars first described by Aristid Lindenmayer. There main usage is the simulation of growth behavior and they are often used in FSPMs.

Simplified: The plant is described a string of turtle commands and its growth is described by rules that define how in each step different parts of this string are replaced by new parts.

Relational Growth Grammars

RGG uses parallel graph rewriting to extend the concepts of L-systems to mathematical graphs. This allows the plant to be a more complex structure including cross references and scales.

In GroIMP RGG is also used quite commonly to describe the integration of XL in the GroIMP platform see: RGG (Plugin)
