摘要
介绍了基于VRML的煤矿床三维可视化的一般方法.该方法将研究区域划分为若干个规则的网格,用距离幂次反比法对煤矿床项底板高程进行插值,形成数字高程模型.依次连接各个网格顶点形成煤矿床顶底板表面和侧面,从而构成一个闭合的三维地质体.运用VRML中的IndexedFaceSet节点构造了一个能够在网络上运行的煤矿床实体,取得了良好的效果.实践表明,VRML为实现网络虚拟现实环境提供了一个可行的解决方案.
The general method using VRML to realize 3D visualization of coal bed is introduced. The studying area is divided into a lot of regular grids and the elevation value of roof and floor is interpolated using Inverse Distance to a Power to form Digital Elevation Model (DEM). And the grid vertexes are connected to form surfaces, forming a closed 3D geological structure. Then VRML node IndexedFaceSet is used to form a 3D coal bed that can run in the Internet. The result shows that VRML is a feasible solution to construct Virtual Environment in the Internet.
