USE OF BANDING TO OPTIMIZE MAP RENDERING IN A THREE-DIMENSIONAL TILT VIEW |
摘要 |
A graphics or image rendering system, such as a map image rendering system, determines a viewing window of a map surface to be displayed. The method generally determines a set of viewing boundaries of the map surface, wherein the set of viewing boundaries divide the map surface into a plurality of viewing bands based on a depth dimension range. The method then determines different zoom level map data for each viewing band and renders a three-dimensional display of the map surface based on the viewing bands and zoom level map data. |
