Tree Modeling Based on GA-Fitted Growth Function

Analyzing the growth rhythm of a plant correctly is very important during modeling its whole growth process. Now the parametric L-system is a kind of popular plant modeling tool in which many parameters are introduced to build up the production rules. To depict growth details of a plant the growth function is combined with the L-system production rules in which the interaction among several plant parameters and time is given. Based on the S-type growth function a tree growth parametric L-system model is set up. Then the function is fitted with the genetic algorithm and three function parameters are fixed. At last a growth function-based tree simulation platform is constructed and the above given model is verified.
