Abstract
The problem of picturization of an object is the problem of determination of what lines to draw in a plane in order that the impression conveyed to the eye shall be that of three dimensional object. In this paper computer procedure for generating line drawings of solid objects bounded by quadratic surfaces is described. It embodies an efficient solution to the 'hidden-line' problem, that is, the problem of determining which parts of an opaque object are invisible when the object is viewed from a given view point. In this paper, we present a method to view a quadratic surface of revolution when it is projected using parallel and central projections.
