Further Information
The aim of the method presented in this paper is to obtain a botanically plausible internal wood structure usable for visualization and rendering in realistic images synthesis. Most of wood modeling methods use 0 and I topological dimensional objects (vertices and edges) even if the final representation is volumic. Few methods use 2 dimensional topological objects (surfaces). The main problem of these methods is the lack of appropriate controls of the wood growth phenomena, particularly concerning connections between branches and the trunk. In this context, we present a new method based on the use of volumic subdivisions of objects providing a more realistic simulation (complying with botanical rules) of internal growth of wood. Moreover and thanks to the object structuring at various levels (growth axe, ring and volume), our approach allows to simplify the evolution control process. This model offers a finer and simpler management of connections between the trunk and branches.
