Abstract
An interface for a graphics system includes simple yet powerful constructs that are easy for an application programmer to use and learn. Features include a unique vertex representation allowing the graphics pipeline to retain vertex state information and to mix indexed and direct vertex values and attributes; a projection matrix value set command; a display list call object command; and an embedded frame buffer clear/set command.
