Abstract


To promote the rise of 3D modeling, computer simulation and virtual reality technology to flourish, all kinds of three-dimensional modeling software platform and simulation system came into being, these platforms and systems provides a powerful design tools and intellectual support, through real-life scenarios The simulation analysis, people can directly start from the three-dimensional concepts and ideas to make intuitive visual design and evaluation system. Mine production applications at home and abroad produced a series of three-dimensional modeling software, which is applied to the design and exploitation of mineral deposit reserves estimates, and achieve good results. As the demand differences, mostly three-dimensional software can not meet the needs of all mines. So, excellent three-dimensional modeling program interface mining and versatile 3D mine modeling software to become a software developer focus. This paper introduces three-dimensional graphics engine library Hoops, using windows programming language VC, in previous studies the theory and technology developed on the basis of three-dimensional solid orebody visualization software system. Topics include: (1) orebody modeling data structures and algorithms. Study of the modeling data model and its caching mechanism; borehole inclinometer data coordinate conversion principle; triangular contour stitching on four basic modes and three basic problems and their treatment algorithm design; Boolean operations based on the OBB tree technology; Based on ore, rock and ore fault model complex building technology; dimensional entities arbitrary cutting technology; (2) visualization software platform design and implementation. In software engineering point of view, is designed based on the hierarchical model of layered software platform architecture, effectively enhance the system's data and functionality of low coupling high cohesion. With the integrated development environment (IDE) VC 2005, using Hoops/3dAF graphics library package for three-dimensional modeling software developers to call the three-dimensional visual modeling of common components, and to achieve a three-dimensional visualization platform orebody. (3) empirical research. On three open pit drilling data were Zhuang engineering applications, to achieve three open-pit ore body village three-dimensional visualization. Engineering applications show that the system is stable, able to accurately simulate the actual three-dimensional structure and ore distribution. The platform can be used as general-purpose software orebody modeling for reserve estimation, mine design, mining development and exploration prediction do basic preparation. Meanwhile, the system provides a three-dimensional visual modeling common components for the mining industry involved in software development interface is ready to do three-dimensional simulation.
