Research on 3D Seismic Data Visualization System Based on PC

结合地震数据的特点 ,研究了科学计算可视化技术 ,从中选择出适合地震资料可视化的以物体空间为序的直接体绘制算法 .编制出基于微机和 Windows平台的三维地震可视化系统Seismic Vis.该系统以面向对象的思想构造 ,采用开放式图形库 Open GL ,具有良好的可扩展性和移植性 ,界面友好 ,具有较好的用户交互能力 .将 Seismic Vis用于实际地震资料的解释 。

By taking the features of seismic data into consideration, the theory of visualization in scientific computing (VISC) was studied. According to the theory, object order volume rendering algorithm suitable for the visualization of seismic data was selected. Based on PC and Windows operation system, the SeismicVis, a visualization system for 3D seismic data, has been developed. The system has used the philosophy of object oriented and OpenGL (Open Graphics Library), which makes it an expandable one with a friendly user's interface and a good ability of user's interaction. So it is satisfactory in interpreting actual data.
