摘要
针对现有巷道三维模型的构建多是基于单机的建模方法,存在网络环境下模型共享困难的问题,研究了一种基于网络三维图形技术的巷道建模实现方法。该方法通过巷道底板中线等特征线和断面参数,经过三维坐标转换得到断面三维线,采用分段建模算法快速建立三角形条带巷道三维模型;采用在网页中嵌入HOOPS 3D流控件和三维模型的HSF流文件实现巷道三维模型的网络发布,并借助网络三维图形技术实现了通过浏览器对大规模巷道三维模型的访问和交互。
In view of problem that most of 3D modeling methods for mine roadway are based on standalone computer and it is difficult to share the models via Web, the paper discussed an implementation method of roadway modeling applying 3D Web graphics technology. The method gets section 3D line through 3D coordinate transformation of bottom centerlines and section parameters, uses section modeling algorithm to establish triangle strip 3D model of roadway; uses HOOPS 3D flow control embedded in a Web page and HSF stream file of 3D model to achieve network publishing of 3D model of roadway, and achieves access and interaction to large-scale 3D model of roadway with the help of network 3D graphics technology and browser.
