基于VolumeViz的地震数据三维可视化关键技术

随着三维可视化技术的应用领域越来越广泛，三维地震数据的信息量过多，三维可视化绘制的运算量过大，渲染速度过慢等问题成为制约地震数据三维可视化技术发展的桎梏.本文基于Open Inventor的扩展模块VolumeViz，通过三维地震数据存储格式的转换实现大量数据的存储，通过自动控制分辨率的方式减少运算量，最后建立场景数据库并渲染实现地震数据三维可视化.

Key Technology of Seismic Data 3D Visualization Display Based on VolumeViz

Along with the application of 3D visualization technology becoming more and more extensive, the problems become the obstacle of restricting the development of 3D visualization of seismic data. For example,the amount of information of 3D seismic data is too much, the computation of 3D visualization rendering is too large and rendering speed is too slow. This paper based on the Open Inventor VolumeViz, through the conversion of 3D seismic data storage format, it achieves the storage of a large amount of data, through the automatic control of the resolution ratio, it reduces the amount of computation. And finally with building the scene database and rendering scene, it finishes 3D visualization of seismic data.
