Based On Opengl Orebody Visualization Research Application And System Development

Due to the geological field is disordered, complex and huge differences,people need to understand not just the presentation of the two-dimensional plane onthe geological body, people are more eager and more directly reflect the need tofully understand the three-dimensional geological structure of space addressinformation space. To this end, geologists often to get some simple informationthrough modern means of geophysical, geochemical and remote sensing. In order toshow geological features from the perspective of a more intuitive, easier to helpgeologists study various geological phenomena, in recent years, scientists in relatedfields combined with geographic information systems, computer science andtechnology research and space technology, database technology, etc. and expand theapplication so that the information in the mining and production managementprocess, there is self-evident and can not be ignored. IT development andunstoppable move pushed by waves wide range of applications, bringingunprecedented vitality of mining industry, but also challenges to be expected,"Digital Mine " is born in such cases the." Digital Mine " is a digital mine (DigitalMine) for short, is a correct understanding of the real mine of information and realthree-dimensional shape of the real scene reproduction.For example, the composition of non-layered structure of complex orebodiesgenerally difficult to describe the simple rules of geometry. Compared to promotethe application subject to the issue of foreign software, Mincomine and GOCAD,the domestic most relevant studies are based on surface model orebody commenced,but often neglect the more important internal distribution of the ore body attributedata. Distribution of ore attribute data can often reflect external factors which oreformation, this paper focus on the three-dimensional simulation study based on theore block model of the internal data regularity. Ore body on which different blockswere undoubtedly taste spatial interpolation and visualization of the entire miningprediction model is important. This paper introduces the spatial interpolation ofscattered points has the advantage of radial basis function neural network model as the basic spatial interpolation. While for defects in neural network training globalconvergence and convergence rate, an improved ant colony optimization algorithmto realize spatial interpolation to build a new model. In this paper, using VC++andOpenGL development environment, the development of the ore body based onimproved ant colony RBF interpolation method for three-dimensional spatialvisualization software platform, and the inclined discrete data storage andprocessing, ore and surface remote sensing image superimposed three-dimensionalmodel simulations show model body rotation, scaling, arbitrary cutting, slicingsimulate any ore, the user can adjust the boundary ore grade and ore custom colorfill a series of interactive features. According to the modeling and user needs furtherresearch and analysis from the perspective of each ore body.
