基于立方体元的Shear - warp体绘制加速算法
摘要
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 interpolation of the equivalent volume element calculations and skip transparent voxels to improve the rendering speed. The experiment shows that the speed of the shear-warp algorithm is improved.关键词
