Abstract

This paper demonstrates a method for three-dimensional (3D) reconstruction and visualization of large scale multidimensional surficial, geological and mine planning data with the programmable visualization environment OpenGL. A simulation system developed by the authors is presented for importing, filtering and visualizing of multidimensional geologically related data. The approach for the visual simulation of complicated mining engineering environment implemented in the system is described in detail. Aspects like presentations of multidimensional data with spatial dependence, navigation in the surficial and geological frame of reference and in time, interaction techniques are presented. The system supports real 3D landscape representations. Furthermore, the system provides many visualization methods for rendering multidimensional data within virtual 3D scenes and combines them with several navigation techniques. Real data derived from an iron mine in Wuhan City of China demonstrates the effectiveness and efficiency of the system. A case study with the results and benefits achieved by using real 3D representations and navigations of the system is given.
