abstract = "We 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.",
