OpenGL Based 3D Visualization of Underground Mining Systems

An OpenGL based 3D visual modeling system of underground mine excavations was introduced. The key techniques for developing the 3D visual modeling system with OpenGL were presented, including entity drawing, geometric transformation, projective transformation, illumination and rendering. The examples of OpenGL application were given and a prototype system for visualizing the underground mine excavation system of a Chinese iron mine was characterised. Some problems for further study were proposed.
