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.

Virtual mosaic wide field of view display system

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.
