Abstract

L+C is a modelling language that combines features of L-systems and C++. It extends the L-system formalism with the notion of fast transfer of information, and supports a number of standard programming constructs absent from its predecessor, the cpfg language. These include modules with structured parameters, productions with multiple successors, and user-definable functions. Visualizations of L-system models can be enhanced using multiple views and the selective display of frames. These features extend the overall range of simulation models that can be conveniently expressed using L-systems, and are particularly advantageous when creating and visualizing complex plant models. A biomechanical model of a growing pendulous branch is given as the key example.
