TL;DR: In this article, a method and system for electronically generating and displaying shaded two-dimensional perspective images of three-dimensional objects in which sharp resolutions of intersections of the objects is maintained, by providing electrical signals representative of surfaces of objects and determining the spatial relationship between these surfaces and progressively smaller portions of a 2D view plane or viewing screen of the display.
Abstract: A method and system for electronically generating and displaying shaded two-dimensional perspective images of three-dimensional objects in which sharp resolutions of intersections of the objects is maintained, by providing electrical signals representative of surfaces of the objects and determining the spatial relationship between these surfaces and progressively smaller portions of a two-dimensional view plane or the viewing screen of the display These spatial relationships are then utilized to determine the surfaces to be displayed within each of the ultimate portions of the view plane or viewing screen
