基于OpenGL实现油藏描述信息的三维可视化显示

3D Visualization of Reservior Description Information Based on OpenGL

油藏描述信息的三维可视化显示,可以使油田地质工作者直观地了解地质现象的几何形态、相互关系和空间分布,准确地进行科学 分析。OpenGL是一种三维图形开发标准,已经广泛应用于在科学计算查视化、电视广播、CAD／CAM、仿真、GIS、娱乐、医学、广告等领 域。该文以VC++作为开发环境,基于OpenGL技术开发了油藏描述信息三维可视化工具,实现了对油藏描述信息进行三维可视化显示应具有 的几种功能:如多角度观察、无级缩放、垂向夸张、拖动漫游、三维旋转等。经应用于油田的实际生产过程中,取得了良好效果。

3D visualization of reservoir deseription information can help geology researcher understand the geometry shape,correlation and special distribution of geologic phenomena and put up exactly scientific analysis.OpenGL is a kind of development criterion of 3D graphics, and has already been applied widely in visualization of scientific computation, vidcoeast,CAD/CAM, simulation, GIS,entertainment, medicine,advertisement,etc. Under the environment of Visual C++ editing, based on the technology of OpenGL, the toolkit for 3D visualization of reservoir description information is developed and realized manifold functions used in 3D visualization of reservior description information, for example, observing from different angle, unboundedly zooming , vertical exaggerating, rambling, 3D rotating, and so on. The favorable result is obtained by the application in producing process in the oil field.
