Research and implementation of 3D modeling algorithm for mine roadway

The authors describe the algorithm of 3D tunnel modeling in detail,develop the algorithm of roadway cross-section modeling,the intersection modeling and smooth processing.The "Roaming System of Three-dimensional Tunnel"(RSTT) has been exploited based on the object-oriented program design and OpenGL,and the practical application shows that laneway modeling algorithm is feasible and the system will be of significance for the application of mining project design and safety production.
