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.
