| 摘 要： | 为满足三维应用的需要,人们开始关注真三维几何体的创建来支撑现实世界中的各种三维对象,这些三维对象可能是一般三维体,也可能是非流形的三维几何体。给出了一种满足现实世界对象要求的三维几何体定义,详细分析了这种三维几何体所需要满足的各种规则,进而结合实例给出了相应的验证方法,同时就三维建模时三维几何体数据的修复问题进行了讨论。

| Abstract: | To meet the needs of 3D solid modeling and applications，we focus on the construction of true 3D solids to support the 3D objects in the real world，regardless of whether the representation of the 3D object is manifold or non-2-manifold. In order to construct true 3D solids，a broad definition of true 3D solids that satisfies the requirements of representations of the physical entities in the real world is presented. Then we explore the rules that a true 3D solid should comply with and present relevant validation methods. Some repair methods were developed during the process of constructing true 3D solids that fulfill the rules for those 3D objects that do not satisfy the rules or validation methods. |
