TUCKER2015-09-292015-09-29841017-4656https://doi.org/10.2312/eg.19841007In space research, there is often a need to illustrate motion, such as a spacecraft's orbital motion and attitude manoeuvres. This paper presents various types of applications for computer generated animation in space research. Some problem areas are discussed, such as scaling in space and time, conflicts between small and large objects, and problems of representation of slow and fast motion. Finally, a particular project is presented, together with the experience gained.10.2312/eg.19841007
