                         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.",
