Abstract
In the real world, many objects do not have smooth, well-defined, and shiny surfaces. Their shapes are irregular and ill-defined and may change with time. These objects are called fuzzy objects by Reeves (1983). Fuzzy objects can of course be represented by geometric primitives. For example, Schachter (1983) describes the simulation of cumulus cloud layers by a concatenation of cloud groups, each consisting of about 75 sun-shaded ellipsoids confined to a circular envelope. Schachter also shows how smoke trails can be simulated by strings of long, thin, translucent ellipsoids. The results, however, are quite unrealistic, although they are useful especially in the case of flight simulators.
