Paper Abstract

Due to the complexity of geometry and topology in three dimensional (3D) spaces, complete description of true 3D objects could not be displaced by traditional 2D GIS in geology, mine, etc. The paper adopts the method of wire frame to construct 3D mine model, based on generalizing several theory and technique problems and thinking about the irregularity of mine. The method is founded on triangular, so it could depict mine flexibly and could calculate the normal vector of triangular constructed to approach the mine survey, which helps to generate illumination model. With the application of OpenGL graphical library, we suggest using the visualization technology in order to produce 3D mine model for geosciences analysis to simply the disposal of 3D model and increase the speed of visual.
