基于纹理的三维地震数据场体绘制

传统的地震资料可视化方法中,采用一组二维切片来表示三维地震数据.这种方法的缺点是不能反映整个原始数据场的全貌及细节,直观性差.体绘制方法克服了这一缺点,它能根据三维数据场在屏幕上产生细节丰富的三维图像,成像质量高.基于纹理映射的体绘制方法借助于图形硬件,采用由硬件实现的纹理映射功能来进行三维地震数据的体绘制,从而明显提高了计算速度.

Texture-based 3D Seismic Data Sets Volume Rendering

In traditional visualization method of 3D seismic data sets,a series of 2D slices are used to indicate the 3D seismic data sets.The disadvantage of this method is that the whole scene and details of the original data sets cannot be displayed.This disadvantage can be overcome by the method of volume rendering,which can generate detailed 3D image on screen from 3D data sets.Volume Rendering based on texture mapping takes advantage of graphic hardware to render the 3D seismic data,speeds the calculation.
