摘要
A method about Level of Detials (LOD) model on the basis of extended octree data structure is proposed for the real-time visualization of massive 3D seismic volume. The LOD model can brick massive 3D seismic volume and build octree level structure to realize 3D visualization of massive seismic data volume on PC. In massive seismic data organizations relatively simple encoding is used to avoid the impact of complex decoding operation on the real-time visualization and encoding/decoding errors during 3D rendering. In massive seismic data management, multi-resolution modeling is used to store the data on each level according to the order of Z-Order, and the establishment of Morton code list has high efficiency for fast query, to meet the real-time needs of massive 3D seismic data volume visualization.
