The UltraScaler graphics accelerator has been designed to deliver industry leading graphics performance for a wide range of applications. Highly optimised, it provides dual channel, high performance, 3D texture mapped graphics. Two novel features distinguish this system. Firstly, the ability to take live video or MPEG video and combine it with 3D textures. Secondly, both channels on an individual card may be combined to form a single display with increased rendering speed. By using the local video expansion bus, up to three other cards may be added to dramatically increase the performance to more than one million fully texture mapped polygons per second.
