【Abstract】 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.更多还原
