AbstractWe present a method for creating tree models with realistically curved branches, useful in the portrayal of natural scenes. Instead of attempting to replicate a tree's - nal shape by observation, we obtain this shape as nature does – by considering the tree's development in the context of its environment. The nal shape of the branches results from their growth in length, girth, weight and rigidity under the inuence of gravity and tropisms. Using the framework of L-systems, we extend Jirasek's biomechanical simulation of a plant axis to correctly represent an entire tree. Our model also simulates the reaction wood which actively reorients a leaning branch by differentiating the wood production in angular portions of the branch cross-section. To obtain realistic and controllable tree architectures, we regulate growth elements in the model using functions based on botanical ndings. We create a multi-year simulation of tree growth under environmental inuences, obtaining a realistic tree shape at every stage of its development.
