Abstract

Over the last few years, a number of researchers in the field of computer graphics have been exploring the use of parallel supercomputers for image generation. This work has progressed to the point that it is now being applied to a variety of visualization problems involving computationally-intensive simulations and large-scale datasets. In this video, we briefly introduce the concept of parallel rendering, and describe several scenarios in which it may be useful for visualizing time-varying data. We illustrate our discussion with several animations which were produced using PGL, a parallel graphics library under development at ICASE. The examples include visualizations of rarefied and turbulent flowfields and an explosive welding process.
