三维地震数据的可视化

摘要
传统的地震数据解释方法是利用地震剖面与水平切片的二维图象显示三维数据,它具有很大的局限性。科学可视化技术的出现使得三维数据三维解释成为可能。将科学可视化技术应用于三维地震数据场,则产生了三维地震数据可视化技术,它主要包括面可视化与直接体绘制两种技术。本文主要研究三维地震数据场的直接体绘制方法——光线投射算法。
The traditional method of seismic data explaination is to use two-dimensional seismic profiles and slices to display the graphics of three-dimensional seismic data,however,it has serious limitations.The emergence of Scientific Visualization technology makes possible of three-dimensional data in three-dimensional interpretation.Scientific visualization techniques applied to 3D seismic data fields,and then had a three-dimensional seismic data visualization technology,which includes technologies of surface and direct volume rendering visualization.In this paper,three-dimensional seismic data field of direct volume rendering-Ray Casting Algorithm is mainly studied.
