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.
