The Research Of Integrated Mechanical Model Rendering On Simulating Tree Growth

In the computer graphics field, many plants models have been used to virtual scene to enhance realism. Improve the fidelity of the plant model has become more challenging research content. Virtual plant is establishing a mathematical model of plant growth and thus get realistic three-dimensional model through a variety of techniques on the computer. As an important component of the virtual plants, tree simulation has been widely appreciated. With the continuous improvement of virtual plants'reality, tree simulation has been widely used in three-dimensional scene of the animation industry. Therefore, to obtain some more realistic shape of trees has become an important goal of graphics.There are different patterns of trees in nature, an important morphological feature of the branches is the bending deformation. In order to describe the local details of trees better, using, to a certain extent improved the tree model's reality and flexibility. Analysis the natural tree structure, improved mechanical model of tendency, according to different parameters of the environment force to get different branch patterns, respectively. Combined L system with, receive the growth of tree trunk position and realize the trees morphological structure simulation in the natural.To further show the natural environment effect on the growth trees, to obtain more effective three-dimensional model, based on diameter variety rate of the tree modeling method, we proposed an integrated mechanical model of tree growth. Start from local branches, comprehensive analysis the natural environment in the growth process of trees, restructured the timing and different effects weight of environment force, and setting up branches bending angle formula, realize integrated force acting on tree growth.Combined tree growth mechanism, improved the mechanical model. Integrated mechanical model with L system, studied and simulated the trees growth in environmental factors, such as gravity, wind, light, obstructions. The experimental results show that this method has good simulation results.
