Research On Mine's 3D Visualization

The Three-Dimensional(3D) Visualization of mine is the application of the Three-Dimensional Visualization in the mine, which is the most advanced field of geography research. On the basis of domestic and foreign research results, this paper made further research in these field, including the source and transaction of the geological object data, building three-dimensional model of object data, modeling methods and the corresponding operation algorithm. This paper mainly did the following researches:Firstly, this paper analyse the object of mine of the 3D Visualization: Natural geological object and artificial projects object; This paper analyzed formula of attaining the three-dimensional coordinates from two-dimensional drawing; to use virtual border drilling to enhance the data density and the definition of the border; Meantime, this paper studied method of ascertaining the virtual drilling under four typical spatial distribution, which is rather important meaning.Secondly, this paper expatiated the process of the mine of the Three-Dimensional Visualization; and analyze the traits of Quasi Tri-Prism Volume(QTPV), building three-dimensional model, optimize the definition of three-prism QTPV's topological relations; and designed the logic data model,the Data Structure of model component elements and objects,and topological relations between them; and designed a drilling database based on characteristic and QTPV's need.Thirdly, this paper studied the modeling algorithm of the QTPV and put forword relevant method of the process of QTPV's modeling on three conditions; and provided us with QTPV's modeling thought of the artificial projects object; and study the algorithm,including the cutting, dividing of the stratum.Finally, this paper developed a prototype system, and made some validation.
