Abstract:
Each tree is unique because of the physical environment it experiences over the course of its life. Environmental factors shape a tree, within the bounds of its genotype. Only by modeling the environment influences can we create realistic models of trees. Our effort is motivated by a desire to construct a predictive tool that can be used by both those in computer graphics and forest management, with applications in image synthesis, dendrochronology, mensuration and the simulation of forest succession. The structural simulation calculates the mass of each branch of the tree to emulate the mechanisms the tree uses to balance its weight, and estimates the photosynthesis return of the leaves to simulate phototropism. We have also created new techniques for blending branches and mapping bark onto the tree surface. Since trees are commonly identified by the appearance of their bark, we have also attempted to model bark that is typical of a particular species, rather than just realistic in general. 1
