摘　　要：平行结构建筑是3维城市中建筑的主体,随着建筑风格的多元化,非平行结构建筑所占的比重越来越大,因此必须对其多尺度表达的方法进行研究。此处根据复杂程度的不同将建筑分为简单建筑和特殊建筑两类。在简单建筑的化简中,首先讨论了倾斜房顶的几何表示方法,在此基础上建立了房顶的关系信息,采用成组处理与斜面的扯直拉平算法相结合的方式实现了简单建筑的化简。在分析复杂建筑倾斜面结构特点的基础上设计了适于复杂建筑的化简方法,并针对两类典型建筑进行了实验。Parallel building is the popular kind in 3D city. But as more and more styles of building come out, unparallel building is becoming more important, so multi-scale representation method of these buildings should be studied. According to the extent of complexity, unparallel buildings were divided into two types in this paper, such as simple building and special building. In simplification of simple building, represent method of inclined roof was discussed, based on which the relation information of roof was established, and then grouping process and squaring methods were combined in simplification of simple building. By analysis of the structure of complex building, an algorithm was developed to simplify complex building and two kinds of typical buildings were experimented by the algorithm.
