    摘要: A method for determining the proper occultation relationship between a calligraphic point and at least one of another calligraphic point and a surface in a raster image, divides the total image screen into an array of spans, each containing an ordered set of pixels which may be further divided into an array of subpixels; determines which of the subpixels on the total screen lie inside each of the raster surfaces and calligraphic points which must be considered for the image totality; then orders the distance of each of the raster surfaces from the viewing point and also orders the distance of each of the point features from the viewing point; and then compares the ordered distances of each point to at least one of the raster surface distances and other point distances to determine which of subpixels of the point or surface/other point are occluded and which subpixels are visible.

    摘要: In computer image generation (CIG) systems, image data for defining pixel modulation values and for supporting a display having a predetermined resolution are determined for defining a scene. For some applications, such as for representing background and/or peripheral areas, it may be acceptable to use data having a lower resolution than the predetermined resolution. Method and apparatus for taking a portion of the image data obtain derived data by a predetermined combination of the portion of image data. Lines of composed data supplied to a display device include a sequence of pixel modulation values selected from the portion of image data and the derived data. In one embodiment the number of lines supported by the image data is doubled with each line containing 50% image data and 50% derived data. Pixel modulation values may be oversampled between adjacent lines of the display for obtaining derived data. Respective composed data for a plurality of display devices may be obtained from a respective plurality of portions of the image data, thus obviating the need to provide additional video processing channels along with associated hardware.
