                         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.",
