Abstract

In this chapter we consider the case of a smooth surface illuminated from one direction and viewed from a different direction. The shade curve and the apparent contour will then interact, but since these curves are not arbitrary curves on the surface the possible interactions are not necessarily the same as those which are possible on a surface with a marking curve or boundary. Since we assume the light projection is stable, we need only consider the case where it is a fold map or a cusp map.
