In order to improve the efficiency of virtual plant modeling based on L-systems, a plant morphology modeling system using an evolutionary strategy is designed and implemented. First the axiom and the productions of an Lsystem are mapped to chromosomes, and then the initial population is designed. Genetic operators are designed to generate the individuals of a new population. The fitness function considers two aspects: the plant outline, and the internal branching. Using the fitness function for evolution, the L-system’s production rules for the target plants can be obtained. Key implementation techniques, function modules, and interfaces of the system are briefly introduced. Finally, the validity of the system is tested in detailed experiments.
