Generating 3D Plants using Lindenmayer System

The main focus of this paper is the analysis of modern methods of algorithmic plant generation. First, a brief introduction is given to the necessary formalism: Lindenmayer system. It is followed by a description of each stage of plant generation process. These include algorithms for obtaining: leaf venation graph, leaf texture, stem texture, and the geometry and topology of the whole plant. In particular, the following approaches have been used: textures are obtained from transformed noise, a general plant description is generated with a parametric Lindenmayer system and a purpose-built particle-based algorithm is used to simulate leaf venation. The last section gives a detailed description of four sample systems used to generate different plants, outlining the reasons why a given system gives the desired graphical result.
