Research On 3d Model Of Mine System

Based on Windows system, this thesis explores 3D visualization of mine simulation system by tool of VC++6.0. It mainly studies underground mine "criss-cross" of the road network system. The roadway is abstracted into road line consisted with nodal points and nodes.This thesiscreates topological relation between elements, and describes data structure by C++ language. It explores overall organizational structure of roadway 3D visualization modeling system adopting algorithm of approximation middle point using cable-point and loading section on node of roadway, also combining object oriented programming and programming with OpenGL technology.To establish roadway 3D visualization modeling system successfully based on 3D graphical visualization theory: Underground roadway can be shown on the computer screen;roadway image database comes from observational data of underground wire directly;summarizing sources of roadway data;managing roadway data by SQL database technology;realizing data input and function of management, addition, deletion and query.etc. Convenient to data edition and query.Through the establishment of models,it can describe distribution of mine roadway more accurately to realize Rotating,Pick-up, zoom and Pan function of mine roadway 3D model. The mine roadway simulation of 3D visualization system explored in this thesis provides important technical support for application of 3D visualization applications in the digital mine.
