Abstract

We present a method for incorporating the biomechanical model of the bending of branch axes introduced by Schaffer and Fournier et al. into developmental plant models expressed using L-systems. The models capture the impact of gravity, tropisms, contact between elements of a plant structure and contact with obstacles on the shape of branches. Sample plants modeled using this technique are compared with photographs of real plants.

Keywords: L-system, biomechanics, elasticity, rod, gravity, tropism.
