GREEN: A Tool for Modelling Natural Elements

Abstract

In this article we present a prototype tool for the modelling of natural elements based on procedural modelling using Random L-systems, or RL-systems. RL-systems are L-systems which are extended using random variables, which permits us to obtain different individuals of the same species based on the same system. The proposed tool is flexible, easily modifiable and extensible due to its implementation using an object-oriented methodology which permits the incorporation of system modules with diverse functionality, such as the representation of specific parts of the element, simulation of tropism or pruning functions. Additionally, the proposed tool permits different interpretations to obtain different file formats depending on the desired viewer application, which permits the connection to other applications for modelling and visualisation of populations.
