    • Method of processing image data to be displayed having a plurality of pixels comprising: a. defining a data queue having a predetermined number of locations therein; b. defining the depth value of the most visible opaque primitive to be displayed at the pixel; c. defining the depth value of the most visible transparent primitive to be displayed at the pixel; d. receiving fragment information belonging to an image to be displayed at the pixel, and; e. determining whether it relates to a visible image with respect to the opaque depth value, and discarding it if it does not, otherwise; f. determining if it belongs an opaque image or to a transparent image; g. if opaque: 1. updating the opaque depth value to equal the fragment depth value, 2. determining if the fragment information is visible with reference to the transparent depth value; and if so; 3. clearing the queue locations and updating the transparent depth values to equal the fragment depth value; h. if transparent and visible with respect to the transparent depth value, updating the transparent depth value to equal the fragment depth value; i. storing the fragment data in the next available queue location; j. repeating steps d. to i. for new fragment info. until the queue is full, or until no further fragment info. is available; k. sorting the entries in the queue in depth value order; and processing in turn fragment info. stored in the queue locations to produce respective pixel display values.

    • A method of processing data relating to graphical primitives to be displayed on a display device using region-based multi-processor architecture, has the shading and blending operations deferred until rasterisation of the available graphical primitive data is completed. For example, the method may comprise the steps of: a) defining a data queue having a predetermined number of locations therein; b) receiving fragment information belonging to an image to be displayed by the pixel; c) determining whether the fragment information belongs to an opaque image or to a blended image; d) if the fragment information relates to a blended image, storing the fragment information on the next available location in the queue; e) if the fragment information relates to an opaque image, clearing the locations of the queue and storing the fragment information in the first location in the queue; f) repeating steps b) to e) for new fragment information, until fragment information is stored in all the locations in the data queue or until no further fragment information is available; and g) processing in turn fragment information stored in the locations of the queue to produce respective pixel display values.
