影像地质编录成果的三维可视化及查询分析方法

在研究及开发影像地质编录信息系统的基础上,基于数字地质编录成果,应用VC 和OpenGL技术,探讨了数字地质编录成果的三维可视化和查询分析方法,并以水电工程地质编录信息需求为例,给出了实现方法.结果表明,该方法对常见岩体工程建模及其地质编录成果三维可视化分析,不仅具有表面纹理映射灵活、场景渲染效果逼真的特点,而且具有同数据库连接方便、与模型对象交互功能强、支持三维空间分析等优点,并可实现岩体工程建模的自动化.

Three-dimensional visualization and spatial query and analysis of result of image geological logging

Based on the exploitation and research of the image information system of geological logging,the ways to realize 3D visualization and spatial query and analysis of result of image geological logging were discussed by use of VC and OpenGL technologies.According to the requirement of information of geological logging in hydro projects,the corresponding method was given.The results show that the present method is not only characterized by agility in surface texture mapping and reality in scene effect,but also easy to be connected with database and of powerful mutual function with users and good effect to support 3D spatial analysis when it is used for modeling of rock engineering and 3D visualization of result of geological logging.Moreover,the method can realize the automatically modeling of rock engineering.
