Ralph W Fisher: Head-mounted projection display system featuring beam splitter and method of making same. Evans & Sutherland Computer, Darby & Darby P C, November 5, 1996: US05572229 (122 worldwide citation)

A head-mounted projection display system featuring a beam splitter displays a simulated environment to an observer using a light-weight, low-cost, head-mounted projector and a retro-reflective screen. The display system optically co-locates the projector with the observer's eyes for effective use of ...

Alyn P Rockwood: Computer graphics system of general surface rendering by exhaustive sampling. Evans & Sutherland Computer, Nilsson Robbins Dalgarn Berliner Carson & Wurst, November 25, 1986: US04625289 (98 worldwide citation)

A z-buffer technique of exhaustive sampling is disclosed for rendering general surfaces in a computer graphics system. The system avoids the need for surface normal calculations or the computation of surface intersections with either ray or plane. It employs a dense surface scan of the object, which ...

Sutherland Ivan E, Hodgman Gary W: Computer graphics clipping system for polygons. Evans & Sutherland Computer, Nilsson Robbins & Berliner, June 11, 1974: US3816726 (92 worldwide citation)

A system is disclosed for clipping three-dimensional polygons for use in a computer-graphics display. The system removes from each polygon all parts that lie outside an arbitrary, plane-faced, convex polyhedron, e.g. a truncated pyramid defining a viewing volume. The polygon is defined by data repre ...

Michael A Cosman, Michael D Drews, Gary S Watkins: Computer graphics system with adaptive pixel multisampler. Evans & Sutherland Computer Corporation, Thorpe North & Western, October 6, 1998: US05818456 (87 worldwide citation)

An adaptive pixel multisampler generates pixel data for display using an interlocking sub-pixel sampling pattern and a frame buffer organized as a per-polygon, per-pixel heap. The interlocking sampling pattern provides the advantages of a multi-pixel shaped filter without pixel-to-pixel cross commun ...

Gary S Watkins, Glen A Eckart, Russell A Brown: Computer graphics priority system with antialiasing. Evans & Sutherland Computer, Nilsson Robbins Dalgarn Berliner Carson & Wurst, April 17, 1990: US04918626 (83 worldwide citation)

Image data is composed from primitives (polygons) to attain data for displays with the removal of hidden surfaces and smooth-appearing edges. Defined polygons are tested for priority in a determined field of vision by scan conversion to specify individual picture elements (pixels). Polygon contentio ...

Sutherland Ivan E: System of polygon sorting by dissection. Evans & Sutherland Computer Corporation, Nilsson Robbins Bissell Dalgarn & Berliner, June 10, 1975: US3889107 (81 worldwide citation)

A polygon-dissection structure is disclosed incorporated in a system for processing geometric data, e.g. data representing three-dimensional polygons, as by subdividing such polygons to accomplish sorting of the data. The system operates to divide a working volume, e.g. a perspective pyramid, into s ...
