摘　　要：阐述巷道三维建模的设计思想:巷道是由一系列的局部巷道组成,局部巷道则由巷道中心线和巷道断面来表达,巷道中心线确定巷道位置,断面确定巷道的空间形态,利用三维矢量的线框模型实现巷道的三维建模.在VC++开发环境下,使用OpenGL实现三维巷道在计算机二维平面上的虚拟显示,采用碰撞检测技术实现巷道三维虚拟系统内的漫游.图6,参6.This article firstly introduced the tunnel three dimensional modeling design concept： The tunnel is composed of a series of pautial tunnels, the partial, tunnel is expressed by the tunnel middle line and the tunnel cross section, the tunnel middle line definite the. tunnel position, the cross section determines that tunnel＇s spatial shape, the three dimensional vector＇s line. frame model realizes tunnel＇s the three dimensional modeling. Under the VC＋＋ development environment, this article realizes the three dimensional tunnel＇s in computer two-dimensional surface hypothesized demonstration through OpenGL, and implements the collision examination when you＇re roaming in the tunnel three dimensional virtual system.
