|
摘要
利用三维可视化软件包,采用Shear-Warp算法实现地震数据的模型可视化,并给出了具体算法流程。实验结果表明此算法可提高地震数据的体绘制速度,实现地震数据解释的实时交互式绘制,为地质勘探提供可视化依据。
Based on the 3D volume rendering technology in computer graphics, the visualization of seismic data model with Shear-Warp algorithm is implemented on the VC++6.0 platform using 3D visualization software package.Experiment results demonstrates that the application of Shear-Warp algorithm can accelerate the rendering process and improve real-time active rendering speed in seismic data visualization, which providing helpful evidence to geographical exploration.
