Creation of Realistic Plants Using Semi-Automatic Parameter Extraction From Photographs

A new semi-automatic method for determining parameters for L-based plant modeling systems is introduced. It is shown that many of the parameters necessary to create realistic plants can be extracted semi-automatically from photographs of real plants. By replacing numerical parameters with a more intuitive set of graphical modeling primitives, it is possible to significantly speed up the design process of complex three-dimensional shapes, such as plants. We also explain how to add small scale detail and natural transitions to skeletal models of plants to further improve the design process.
