In many applications of three dimensional computer graphics, the appearance of the same scene must be computed repeatedly for many different positions of the viewer. This paper concerns a scheme for exploiting this property of an application for the purpose of improving the efficiency of the hidden surface computation. The scheme involves a kind of… (More)
Preliminary analysis of radar altimeter data indicates that the instrument has met its specifications for measuring spacecraft height above the ocean surface (+/- 10 centimeters) and significant wave height (+/- 0.5 meter). There is ample evidence that the radar altimeter, having undergone development through three earth orbit missions [Skylab, Geodynamics… (More)
