,丰富了建筑物室内空间LOD的表达理论.为构建这种LOD模型,提出基于胞腔复形链边界算子和上边界算子的LOD生成方法.该方法引入代数拓扑的胞腔,胞腔复形和复形链3个概念,利用胞腔和胞腔复形表达LOD,并在LOD6的基础上,利用边界算子和上边界算子生成其他粗空间粒度LOD模型,为三维城市模型建筑物LOD构建提供一种新方法....
Objectives: Aiming at solving the problem that the representation of level of detail (LOD) for existing buildings is mainly external and seldom involves the internal space objects, a conceptual model of three - dimensional (3D) LOD for buildings with interior space structure is pro...
