VOLUME RENDERING METHOD FOR 3D SEISMIC DATA BASED ON GPU
摘要
Abstract
Volume rendering is one of the focuses in the research and application of computing visualisation.On the basis of formally defi-ning the 3D data volume,we discuss the principles and methods of the ray casting algorithm including division of volume data,computation of resampling and composition of image.By resampling with shader and image compositing,the GPU acceleration of volume rendering is achieved.The application of the ray casting volume rendering algorithm with GPU acceleration in seismic data interpretation implements the visualisation of seismic data in gray and pseudo-colour respectively,and by a transfer function,the characteristics of stratums in seismic data field is highlighted,which overcomes the limitations of the profiles,slices and 3D surface rendering of seismic data.关键词
