摘要:
 为建立具有较强真实感的观赏性树木模型，以南方小叶榕树为建模研究对象，结合参数L系统，提出了根据特征差异性进行分步建模的方法。首先从整体的角度对小叶榕树的形态特征进行分析，之后把树木不同部位的特征参数化，结合参数L系统建立具有二级映射关系的产生式规则，以此构建具有良好交互性的小叶榕树枝干模型。在最后绘制模型时，为减少模型的数据量以及保证绘制的高效率，使用改进的矩形面片拼接的方法来实现这些要求，借助OpenGL图形库绘制出整棵榕树的模型。实验结果表明：绘制出的模型数据量小，具有较强的真实感以及良好的交互性。
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.
