【摘要】 地质体三维可视化是科学计算可视化研究领域的重要分支。如何把地下无法透视的构造信息,进行三维可视化,一直是地学领域的热点和难点之一。基于此,针对层状地质体的结构特征和三维建模方法进行了研究,在此基础上运用开源可视化工具包(VTK)和应用程序开发框架QT,完成对层状地质体的三维建模及可视化。最后结合兴城深部探测野外示范与实验基地的实际地震勘探数据,实现了对该区域的地质模型构建及立体展示。实践表明,使用VTK和QT作为层状地质体三维可视化的开发工具是可行的,完成了该区域6个地层地质体三维建模以及结合地震数据的综合三维可视化。更多还原

【Abstract】 The 3D visualization of geological objects is an important branch in the research area of scientific visualization. The 3D visualization of construction information underground which cannot be perspective,it has been one of the hot and difficult in earth sciences. The structural characteristics of stratified geological objects and threedimensional modeling were studied. The 3D visualization of stratified geological objects were completed with the help of using VTK and QT. Finally,the construction of geological model and three-dimensional display combined with actual seismic data of deep exploration field demonstration and experimental base in Xing Cheng were realized.The practice shows that using VTK and QT as a stratified geological 3D visualization development tools are workable. The 3D modeling and integrated visualization were completed with seismic data of six stratigraphic geological objects in the area.更多还原
