【摘要】 多层三维空间实体普遍存在于现实生活中。借助于目前国际最广泛应用的三维图形接口OpenGL将其真实地显示出来,具有重要的现实意义。其中多层三维空间实体建模技术是显示过程的关键步骤。在实现单层空间实体三维建模的基础上,利用OpenGL实现了多层三维空间实体叠加建模,叠加实现的过程及其属性数据的表示方法。更多还原

【Abstract】 Multi--layer 3D spatial entity exits widely in morden society. It is important to visualize multi--layer 3D spatial entity using OpenGL (a standard Graph Library). It is a key technique to model multi--layer 3D spatial entity. In this paper, based on 3D modeling of single layer, overlay modeling of multi--layer 3D spatial entity is finished. And the overlay process and feature information of multi--layer are described too.更多还原
