Reorder superimposed digital image data and associated digital image rendering engine

摘要

A digital image processing system for rendering an image in a display, comprising; a communications network interface; one or more processors; one or more memories coupled to one or more processors; a routine stored on at least one of said memories and using one or more processors to retrieve an original set of superimposed digital image data comprising a plurality of original levels of image data arranged in ascending order and rendered in a display wherein each original level of image data comprises a plurality of image objects of different types arranged in an intermediate level image object order; a routine for reordering digital image data stored in the one or more memories and, when executed by the one or more processors, extracts a first set of image objects of the first type from said original set of superimposed digital image data; A set of rearranged image data, and wherein said set of rearranged digital image data comprises a first level comprising image objects of the first type, wherein the digital image data reordering routine rearranges the image objects of the first type such that all image objects of the first type Of a certain level of the original planes of image data in the rearranged digital image data before any image objects of the first type from any original planes of image data following in ascending order of the particular plane of the original planes of image data, and so that each of the image objects de s of the first type from the particular plane of the original planes of image data in the rearranged digital image data after all the image objects of any original planes of image data which are in ascending order before the particular plane of the original planes of image data, and wherein the image objects of the first type of image data each of the original planes of image data in the rearranged digital image data is arranged in reverse order to the inter-level image object order of each of the original planes of image data; and a routine for assigning a Z value stored in one of the memories and assigning a Z value to each image object in the rearranged digital image data depending on the order of the image object in the rearranged digital image data.
