摘要
针对三维地质构造建模过程中地质曲面(层位面和断层面)和地层网格海量数据的组织、管理和可视化显示等技术难题,提出并实现了一种基于外存的海量三角网格多分辨率数据组织技术,解决了地质曲面海量三角网格实时显示的难题;采用数据分块和层次细节(LOD)模型等技术,实现了一种针对地层网格海量数据的多分辨率数据组织和管理技术;为了增强三维地质构造模型海量数据三维可视化显示的实时性,提出并实现了一个基于外存的三维地质模型海量数据调度与可视化框架,解决了三维地质建模软件系统研发的关键技术问题。
In order to solve the difficulties on the massive data organization,management and visualization of geological surface(layer surface and fault surface) and formation grid during 3D geological structure modeling,we propose and realize a technique for massive triangle-grid multi-resolution data organization based on external storage,which solved the difficulty of realtime display for massive triangle-grid of geological surface.By using data sub-blocks and level-of-detail model,etc,massive data multi-resolution data organization and management of formation grids is realized.In order to enhance the performance of 3D visualization display for massive data of geological structure model,we propose and realize massive data dispatch and visualization framework for 3D geological model based on external storage,which solved the key technical problems in the development of 3D geological modeling software system.
