煤矿三维巷道建模技术研究

研究了煤矿巷道三维建模中的部分问题，包括巷道建模、巷道交点建模和碰撞检测。结合巷道中心线节点上加载断面的思想建立了单一巷道模型，利用曲线插值的方法解决了交点建模的问题，用经典包围盒法实现了漫游时的碰撞检测。并采用VC＋＋．NET开发平台，结合OpenGL技术实现了煤矿三维巷道的虚拟显示与漫游，给出了实验效果图。

Modeling Technology Study on the Three-dimensional Laneway

This paper investigates parts of the problems of the coal mine laneway modeling,which includes laneway modeling, laneway point of intersection modeling and collision test. It sets up the single laneway model by combining the ides of loading the section over the point of laneway center line, solving the problem of nodical modeling by using the curve interpolation, and making the collision test came true when ramble by using the typical surround box method. At the same time, based on the VC ＋ ＋. NET development platform and the OpenGL technology, it achieves the virtual display and amble of 3D laneway, giving the test result map.
