摘要

Lindenmayer systems (L-systems) were introduced by Aristid Lindenmayer to generate the geometrical structures, i.e. plant, leaf, or root structures. During the last decade in L-systems prototype, the plant growth has been animated by composing images from all iterations. The problem is that development of plant model at each time step is nonsmooth and discontinuous as nature. In this paper, we solve this problem by incorporating some mathematical time functions of logistic growth into plant development model, the development becomes more smooth and continued. The growth life cycle consists of five stages. There are growth stage, stable stage, decreasing stage, stable stage after decreasing stage and death stage. The stochastic and bracketed L-systems are applied to generate the stochastic structure and branching structure, respectively. Our L-system prototype can generate both plant shoot and root parts. The shoot and root parts are related to each other. The results of simulation and visualization are presented. These show that the simulation and visualization of the development of the plant growth modeled by using the new proposed method is smoother and more natural.
