Application of L-system in Plant Simulation

With the development of fractal, virtual plant has been a very interesting problem in computer graphics. For its simple definition and highly structurization, L-system has been one of the most common methods in plant simulation. This paper introduced the basic concept and expressive principle of L-system, and modeled plants by using computer. Considered some growth characters of plants such as photokinesis and geotropism, disturbancy variable and randomness were introduced into L-system in order to create more natural and more living image.
