基于L-系统规则组合机制的植物建模新方法
A New Plant Modeling Method Based on Rule Compound Mechanism of L-System
摘要
Abstract
L-System is a dominant method for tree modeling based on botanical rule, which has been widely used in virtual plant modeling and application. However, great challenge still existed in practice, such as difficulties in extraction of L-system rule and inconvenience in modeling. In order to solve these problems, L-system rule compound modeling method was present, which is beneficial for reuse of tree morphologic geometry and growing rule. Based on various basic libraries composed of ramification, phyllotaxis, inflorescence, fruit and others, the method constructs 3D geometric tree model by assembling different organ models from those libraries and integrating the knowledge of plant morphology and physioecology along with the measured data of plant morphological factors. This method is proved well by achieving the 3D longan tree and other tree models quickly. At present, it is more suitable for tall tree with complex organs, but not all plants. By introducing this method, we hope to reduce the difficulty of L-system modeling and to achieve the purpose of rapid modeling.关键词
