synopsis = "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.",
