摘要: 为了获取三维地质体任意方向的剖面图,在四面体建模的基础上,利用面与面之间的相切关系以及四面体剖切后拓扑关系的一致性,在三角形自分解基础上完成了三维地质体的任意剖切,并在VC环境下利用OpenGL对该剖切进行了显示。仿真结果表明,该方法实现了三维地质体任意方向的剖切处理,提高了绘制地质剖面图的效率。

Abstract: In order to meet with requires of high reality and verisimilitude of walkthrough system of 3D roadway, the paper proposed a common framework model of walkthrough system of 3D roadway based on engine-mode. It discussed functions and working flow of main control module, physical system module and rendering system module in the framework in details and gave solution scheme of the system under B/S mode. The simulation result showed that walkthrough system of 3D roadway based on engine-mode has higher degree of simulation and faster speed of walkthrough comparing with walkthrough system of 3D roadway based on basic API.
