Abstract
A method of encoding and storing locations of bounding boxes of drawing primitives to be rendered on a multi-resolution display that includes a plurality of regions of different resolution, at least one of which is subdivided into a plurality of sub-regions. The method includes steps of dividing the viewable area of the multi-resolution display into four quadrants and encoding only selected attributes of each of the plurality of bounding box locations within only one of the four quadrants of the multi-resolution display. The encoded selected attributes are then stored in a number of locations of a memory. The selected attributes include information regarding the regions of different resolutions within the multi-resolution display and the boundary lines therebetween, such as the region of lowest resolution partially covered by each of the bounding boxes; either the number of boundary lines cutting each of the bounding boxes or the number of sub bounding boxes forming each of the bounding boxes; either the direction of the first boundary line cutting through each of the bounding boxes or the direction of the sub-region of lowest resolution partially covered by each of the bounding boxes; and an indication as to whether a portion of the region of lowest resolution appears on both sides of the first cut cutting through each of the bounding boxes.
