Abstract

We propose a real-time interactive system that enables users to generate, manipulate and edit the shape model of a tree based on growth simulation by directly indicating its global and spatial information. For this purpose, three-dimensional (3D) spatial information is introduced to the well-known L-system as an attribute of the growth simulation. Moreover, we propose an efficient data structure of L-strings in order to speed up the process.
