Study and Realization of Three Dimensional Visualization of Mine Geological Objects

The basic framework is proposed to establish three dimensional (3d) visualization of mine geological objects, and carries through effective analysis to the key technologies of 3d mine geologic objects. Kriging method is used in drill hole data interpolation to construct the constrained delaunay triangulation net (TIN). Through linking the corresponding triangular grids of two consecutive layers to be treated into imitated triangular prism cells. These cells can be used to construct 3d geologic objects stratum. In the process of achieving improved delaunay triangle net methods. The design and main algorithms of 3d mine geological modelling are also studied.
