Abstract: In view of problem that most of 3D modeling methods for mine roadway are based on stand-alone 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.
