ActiveX技术在三维地震资料可视化中的应用

Application of ActiveX technique in 3D seismic data visualization

文章在介绍了三维地震资料可视化原理的基础上,利用SGI的OpenInventor实现了:(1)三维地震数据体的切片(主测线、联络测线、水平方向)显示;(2)数据体切片的移动、缩放、旋转;(3)视觉效果可以选择,可以调节数据体的透明度、颜色;(4)地震“电影”的功能.结合ActiveX技术,将以上功能实现封装为ActiveX控件,嵌入到PowerPoint中,实现了地质汇报中三维地震资料的动态显示与控制.

Based on briefly presenting the basic principle of 3-D seismic volume visualization, this paper gives us some results using the kit of OpenInventor of SGI. The results include four aspects.. One is the rendering of three kinds of slices （Inline, Xline and horizontal one） ; Second is translating, rotating and scaling the slice geometry image; Third is we can change color and transparency from seismic data in order to reach some kinds of effect; The last is the realization of seismic movie. Additionally, the results mentioned above are encapsulated into ActiveX control with ActiveX technique and this control is imported into PowerPoint. So we can render the seismic data and have control of rendering as we want in geological report application.
