Abstract
A method for interfacing to ultra-high resolution output devices. The basic idea of the present invention is to subdivide an ultra-high resolution display screen into narrow strips or column subsections, thereby enabling the mapping of multiple pixel interfaces to it. In this manner, the full pixel display is completely mapped. As such, multiple image generators are able to create in parallel their specific narrow strip of the full pixel display using view frustum culling, which is known by those of ordinary skill in the art. It should be appreciated that an interface in accordance with the present invention is not tied tightly to a scanning architecture. As such, this keeps a level of abstraction between the image generator and the many different types of display devices. Furthermore, since this interface is by design a rasterization interface, more image generators and less expensive image generators can be used for driving the display device. Moreover, by abstracting the interface, it necessitates a line buffer within the display device, thereby removing the need for transferring the pixel data in actual real-time.
