摘要
采用CSG和BR集成的模式表达3维空间数据,提出一种基于CSG-BR模型的3维实体可视化建模方法,以复杂空间实体的分解为切入点,通过建立起CSG与BR面之间的对应关系,设计CSG-BR模型的数据结构,并在网路环境下构建基于CSG-BR模型的3维实体可视化系统模型,表达了复杂实体的完整特性,为3维实体虚拟仿真、动态表达和空间分析研究提供参考。
This paper adopts CSG and BR integrated pattern to express 3D spatial data and proposes one kind of 3D entities visual modeling method based on CSG - BR. It designs data structure for CSG - BR model starting with the decomposing of complex spatial entities as the breakthrough point and within the correspondence between CSG voxels and BR surface. And then based on CSG - BR model, it devotes to constructing 3D visualization system model in the network environment and expressing the complex entity complete properties for providing the reference to 3D virtual simulation, dynamic expression and spatial analysis.
