The Establishment Of Three-dimensional Model Of The Mine Shaft

Construction of underground tunnel in the digital mine plays a very important position, three-dimensional simulation shows The roadway layout and others can make mine the number of mining activities, visualization, accurate and timely recording and performance changes in roadway projects. And it also Can improve the efficiency of the mine and manageable,To guide the design and construction of mining and so is of great significance.Firstly it explains the three-dimensional visualization of modeling tunnel research status, Discussed the three-dimensional data model and data structure of some of the basic theory,This article then describes the process of database design and build, and it Based on this database design and building of topology was constructed using a database SQLServer2000. Combined with the former given the traditional center line transect, And on this basis to improve, using the combination of DirectX and Visual C#, Using Visual C# programming language through the establishment of three-dimensional model tunnel, And using DirectX complete the three-dimensional visualization.This paper rely on the roadway data of Dahongshan copper mining, Combining the characteristics of data mining tunnel and choosing the principle of three-dimensional data model, from the data organization To data extracted, Summarized roadway tunnel body node and three-dimensional data structure. It design three-dimensional model of roadway built algorithm, Especially in the fork in the Department's unique method of internal processing gateway, In the previous progress based on a certain. And visualization of three-dimensional graphics based on the theory successfully established a tunnel visualization system:(1) completed the data entry roadway and data management, Such as:add, delete, query functions(2) achieved the formation of roadway, The process can be summarized as:from Gateway node to Roadway centerline to Single Entry and at last Generation of multiple tunnel.(3) solved the roadway in the tunnel junction smooth integration issues, Particularly dealing with problems when a number of roadway intersecting at one point. Roaming lay a solid foundation for the later.(4) the use of DirectX for Visual roadway, Projection, rotation transform to implement, Select and add texture, All these have contributed to the enhanced tunnel simulation of realistic.(5) can choose automatic or manual roaming roaming, On the roadway within a free and easy browsing.(6) The main roadway within the roaming to roam along the roadway center line, Real-time knowledge of the location point of view,It Can also move within the roadway, setback and other functions.
