The Study Of 3D Visualization Modeling In Strip Mine Deposit Geological Model System

The article centers on the development of open pit mine's 3D visualization deposit model. The deposit model includes geological surface model and body model. The geological surface model is composed by the geological interface and the earth's surface. The interpolation face of geological interface is trimmed by boundary and the closed polygons of up and down faulted blocks to form the trimmed surface. The body deposit model is composed by the trimmed surface of geological interface and the triangulation earth's surface according to spatial relationship of these elements. Yimin open pit mine is taken for example, the 3D deposit model visualization system has been developed on VC++6.0 and OpenGL. The system can display the 3D deposit model in any direction, found graphics data of deposit model, modify and update the deposit model and draw any direction section.
