High definition graphics application in fluid flow simulations

Abstract

NASA Ames is using high spatial/color-resolution computer graphics to interactively visualize flow fields generated by supercomputer solutions for the flow about such vehicles as the Space Shuttle. The scientist's viewing position in three-dimensional space can be interactively changed while the fluid flow is either frozen or moving in time. Animated sequences can then be made for workstation viewing with the aid of specialized software that allows easy editing and automatic 'tweening' of the sequences. Attention is presently given to the software generating the three-dimensional flow field displays, as well as that for creating the animation sequences.
