3D Data Field Visualization Modeling Technology for Geological and Mining Engineering

OpenGL is a widely- used 3D graphic programming library. The paper presents an openGL-based technology for realizing the 3D data field visualization modeling of geological and mining engineering and the interactive operation method, including the OpenGL principles, the structralization processing of the data of geological and mineral objects, the data structural model of their 3D data field, the imaging and presentation of geological drill holes and orebodies and the OpenGL techniques applied such as rendering, list display and double buffering. These methods and techniques were integrated in the computer modeling in a real case study of an iron mine and achieved good results, verifying the effectiveness of OpenGL technology in the study of visualization modeling system for geological and mining engineering.
