基于Hoops的钻孔三维可视化技术研究

A Research on 3D Visualization of Drillings Based on Hoops

在矿体三维可视化建模过程中,钻孔和品位的三维可视化是其关键步骤之一,该文引进三维图形引擎库Hoops,采用Windows编程语言VC实现了钻孔轨迹及其品位分布三维可视化组件,为开发矿体的三维实体模拟软件系统奠定基础。工程应用表明,该组件性能稳定,能够精准地模拟实际钻孔分布情况。

Three-dimensional visualization of drillings and ore grade is the key part of the 3D visualization and modeling of mines.And its realization lays a good foundation to the software of three-dimensional solid modeling,which simulates ore bodies.On the viewpoint of generalized visualizing system,and according to the software engineering principle,the database structure of drillings is built,the coordinate conversion principle of measured drill-data is analyzed,and the hierarchical structure of the system is designed.Based on Hoops/3dAF library,a 3D visualizing module of drill-data is finally realized with VC2005.Practical applications show that this module′s performance is stable and can accurately simulate the actual distribution of drillings.The paper provides reference for the majority of mining software developers,and promotes digital construction in mine.
