| Abstract: | Large-scale 3D seismic data direct volume rendering is a double-intensive problem of computing and data.In order to enhance the reconstruction efficiency of 3D seismic images,a shear-warp algorithm is applied for 3D seismic data based on cube data structure.The algorithm constructe linkages between voxels by cube structure;then classify the cubes by the characteristics of seismic data.In the drawing process,it use the binary tree index to quickly find the classification results,use the results to avoid the ... |
