在利用拓展的二维半算法为半结构对象的树木构建逼真模型的过程中,如何将单体模型构建出树木静态模型所需的组合体形态则是重点研究的问题。若干单体组合过程中,存在接触面之间的遮挡现象。利用改进的消隐算法处理接触面、线段的关系,完成组合效果;描述涉及部分的数据存储结构。
During constructing tree modeling based on expanding 2.5D modeling, the important key is how to construct combination solid modeling with several monomer modeling. Trees are semi-structure objects. In some monomer combi-nation process, the occlusion phenomenon is in relevant interface. This paper analyzes relationship between corresponding interfaces or line segments by improved blanking algorithm, completing the combination effect. It describes relevant data storage structure.
