Abstract : This paper describes an algorithm, capable of parallel implementation, to calculate the perspective image of Generalised Cylinder, from arbitrary viewpoint, with hidden surface removal. It applies to a wide class of cylinders. The time taken will be proportional to the total length of the contours, independent of the number of edges. The algorithm solves for one closedloop contourgenerator at a time, testing its contour (in the image plane) for intersection with visible segments of previous contours. The input are the functions describing the object, along with the position of the eye; and the output are the visible surfaces and edges.
