基于参数L系统的小叶榕树建模方法研究
Research on Modeling Method of Ficus Microcarpa Based on Parametric L System
摘要
Abstract
To build the ornamental tree model with a strong sense of reality,taking the ficus microcarpa tree as the modeling object,com-bined with parametric L-system,a method about multi-step modeling based on characteristic difference is proposed. First the morphologi-cal characteristics of ficus microcarpa tree is analyzed from whole angle,then the characteristics of different parts is converted into param-eters,to build generative rules with two levels of mapping relations on the basis of L-system,and the branch model of tree is established with better interactivity. In the part of rendering model,in order to reduce the model data and guarantee the high efficiency of rendering, an improved method of mosaicing rectangular planes is used to meet the requirements. Finally, the whole model is rendered by using OpenGL graphics library. Experiment shows that the ficus microcarpa model has a small amount of data,a strong sense of reality and good interaction.关键词
