基于OpenGL的二维电法数据三维可视化技术研究

The Research on 3D Visualization of 2D Electrical Prospecting Data Based on OpenGL

结合目前电法勘探数据成图及二维解释的特点及存在的局限性,研究了OpenGL和VC++2005联合编程,结合二维剖面数据特点,研制了基于OpenGL的电法数据三维可视化系统Geo3DVis。Geo3DVis的基本功能包括工区建立、二维解释、三维显示;实现了对二维剖面数据的动态放大、缩小、平移等交互操作。将Geo3DVis应用于实际二维物探数据资料解释,取得了良好的地质效果。

With the characteristics of the present electrical prospecting data and 2D interpretation as well as the existing limitations,the combined programming OpenGL and VS2005 are studied.Based on 2D profile data characteristics,the system of Geo3DVis based on OpenGL is developed.The function in Geo3DV includes the building of work areas,2D interpretation and 3D visualization.The interactive operation is realized like the zoom in any size,move etc.The application of Geo3DVis to 2D geophysical data interpretation achieves a good result.
