地矿三维建模及可视化的研究

RESEARCH ON THREE-DIMENSIONAL MODEL RECONSTRUCTED OF GEOLOGY AND MINE AND ITS VISUALIZATION IN OPENGL

摘要: 地矿三维建模及其三维可视化对地质、矿藏信息的获取及地质现象解释具有十分重要的意义。采用基于TIN的多层DEM方法,实现层状地矿实体模型的三维重构,借助于OpenGL图形库实现了层状实体模型的三维可视化,并对模型进行了光照渲染、漫游和切割等操作。

Abstract: Geology and mine three-dimension reconstruct and three-dimension of model have important meaning to geology explaining and information Obtaining.This paper realizes three-dimension of the stratum model,based on TIN multilevel DEM method,with the aid of OpenGL,in realizes three-dimension visualization of stratum of stratum model,and carries on oprations of illumination,roams and cuts etc.
