Volume Rendering Method for Spatial Seismic Data Based on GPU
Volume rendering is one of the focuses in the research and application of computing visualization.On basis of the spatial data volume formally defined,principles and methods are introduced on the division of volume data,computation of resampling and composition of image in the ray casting algorithm.By resampling and compositing with shader,the algorithm is successfully improved in performance by GPU.The application of the algorithm in seismic interpretation is implemented for visualization of spatial seismic data in gray and pseudo-color and a transfer function is designed to highlight the characteristics of stratums in seismic data field,overcoming limitations in the visualization of profiles,slices and surface rendering of seismic data.
