Abstract: A display system, which is useful for simulation, and training system that provides a mosaic wide field of view display by alternating virtual and direct view display images through the use of a new optical beamsplitter/combiner device. Edge blending and the use of flat panel display devices are used to provide a high brightness, high contrast, high reliability, and continuous unobstructed field of view. The new optical beamsplitter/combiner has an optically flat reflective portion and a curved transmissive portion.

Abstract: A device is provided for rendering computer graphic images with a database and geometric processor to process a plurality of polygons. The device includes a background rendering engine to render the polygons received from the geometric processor. A critical item detector is configured to identify polygons received from the geometric processor that have at least a portion of the polygon within a critical item region. In addition, a critical item rendering engine is included to render polygons identified by the critical item detector. The identified polygons in the critical item engine are rendered at a higher resolution than the polygons rendered by the background rendering engine. A critical item load manager is coupled to the critical item rendering engine to increase or decrease a critical item load being rendered by the critical item rendering engine, and to match a deterministic processing time allowed.

Abstract: A Schlieren-type color television projector utilizes a fiber optic rear projection screen (FORPS) at an initial focal point to translate the spatially separated, converging rays of component colors produced by the Schlieren-type color television projector into a plurality of spatially combined, diverging rays of combined colors which are then suitable for further processing by a conventional optical lens system which can either aperture or vignette the image without color fringing, separation, or a shift in the color balance normally experienced when aperturing or vignetting a Schlieren-type color television image.
