Generic singularities of rays emanating from a space curve in R^3 in all directions with the rate determined by an indicatrix (independent of the point in R^3) defined by a surface are classified. Similarly rays emanating from surface defined by an indicatrix given by a curve are also considered. Some applications to control theory are indicated.
