It is important to develop visualization methods for comparing numerical predictions of large hull dynamics with whole scan experimental determinations because large quantities of detailed data must be examined in order to verify the consistency of the two results or to characterize significant differences. In this talk a variety of animated visualization methods based on the Explorer software package running on a visual processing computer will be described. Procedures followed to develop typical visualization programs will be explained. The methods will be illustrated with animated visualizations of hull dynamics data obtained both numerically and experimentally which show and compare surface pressures, velocities and intensities, slice views of the acoustic nearfield and 3-D radiation patterns. Examples of animation with respect to time, frequency and viewing aspect will be given. [Work sponsored by NAVSEA.]
