基于OpenGL的煤矿地震数据三维可视化

Study on 3D Seismic Data Visualization for Coal Mines Based on OpenGL

结合煤矿地震数据特点,研究了OpenGL和VC++6.0联合编程,利用适合地震数据三维显示的算法,研制了基于Windows的煤矿地震数据三维可视化系统Sgy3D。Sgy3D的基本功能包括数据体、Inline剖面、Crossline剖面、层位、等值线、任意测线等要素的三维立体显示;实现了对数据体的动态放大、缩小、平移等交互操作。将Sgy3D应用于实际地震资料解释,取得了良好的地质效果。

Considering the features of 3D seismic data for coal mines, the programming combined with OpenGL and VC＋＋6.0 was studied. Based on seismic data characteristics, the system of Sgy3D was developed. In addition, The functions in Sgy3D include the elements such as data, profile of inline, cross line, time slice, contour, arbitrary line and so on, which realize the interactive operation on data. The application of Sgy3D in seismic data interpretation is good for seismic exploration and real-time seismic analysis.
