frustum

Based on that, the thought of divide and conquer was adopted to build the highway 3D model, thus technologies as frustum culling and level of detail were applied to accomplish the view-dependent simplification of route 3D model, and the highway 3D browsing platform was worked out.

在此基础上，采用分割归并思想建立了路线三维模型，应用视锥截取、LoD技术实现了路线三维模型的视相关简化，并开发了公路三维场景的实时动态浏览平台。

An approach of division and combination for capacitance is obtained by using two coaxial and parallel conducting surfaces of a frustum of a prism of regular polyhedron with the same height and two undersides in a plane respectively.
