A Research on 3D Visualization of Drillings Based on Hoops

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.
