AB: Accurate, fast, and convenient visualization of large data sets is a recurring need in seismic data processing and analysis. Modern data viewers should exploit state-of-the-art volume rendering technologies to effectively generate images with short time delays and maintain viewer interactivity. A new data viewer called Vis3D is presented which uses a wavelet-based multi-resolution framework to achieve fast volume rendering. Each data set is converted into a multi-resolution pyramid, and the resolution most appropriate for the available computing resources is chosen. Multi-resolution representation enables large data sets to be visualized on even low-end computers, supports progressive refinement of low-resolution images to higher-resolution images, and accomplishes level-of-detail selection so that only a necessary level of detail is rendered. The data viewer also includes viewing of slices along arbitrary directions, customization of color maps and histogram-based color scaling, and changing of directional lighting. Vis3D can be a convenient tool for geophysicists faced with the challenge of visualizing increasingly larger data sets.
