5203 |a"This report describes a computer-generated animation of the dynamics of a flexible body which consists of a long dipole antenna mounted on the Shuttle. The work is a part of a joint NRC-NASA program, Waves in Space Plasma (WISP). The animation facility consists of a PDP-11/45 and a modified NORPAK Incremental Graphics Processor (IGP). An analytical formulation, in which the antenna deformation is represented with a product series of time-dependent variables and simple polynomial shape coordinates, was found to be a good choice for the animation. The computer and graphics facility enabled efficient on-line animation. In a mode where calculations are done off-line, speeds of 60 times faster than real-time were achieved with no problems"--Abstract, page 1.
