摘要： Image data is processed so that polygons can be displayed on a screen of scanned lines. A first memory stores at least X and Y coordinate data for edge points of the polygons. A second memory stores polygon numbers arranged in a processing order. A first computing unit computes data for sides of each polygon corresponding to each polygon number stored in the second memory. A second computing unit computes edge pair data in accordance with the data for sides of polygons, the edge pair data including a pair of edge points located on the scan lines. A third computing unit computes data for a start point and an end point of each polygon based on the edge pair data. Finally, a processing unit processes the start point and end point data to obtain polygon dot data and outputs the dot data in synchrony with the scan lines.

摘要： A sorting processor has a polygonal priority order generating circuit. The polygonal priority order generating circuit includes a memory for storing information of centers of plural polygons; a position setting section for transforming a coordinate of each of the polygonal centers from an object coordinate to an absolute coordinate; and a visual field transforming circuit for transforming the transformed coordinate as a position set object obtained by the position setting section with respect to a visual field. The sorting processor further has a sorting circuit for sorting transformed results about the visual field on the basis of Z-axis information. There is no frame delay due to a need to wait until the polygonal information is completely sorted. Further, it is not necessary to use a RAM for storing information geometrically transformed before a sorter.

摘要： A clipping processor has a first polygonal end point memory for storing two end point information of X and Y constituting a polygon and respective end point information of mapping information. The clipping processor also has a screen side generating circuit for judging whether a polygonal side crosses each of screen end points and is located inside or outside a screen based on the two end point information from the first polygonal end point memory. The clipping processor further has an intersecting point arithmetic circuit for calculating an intersecting point on the polygonal side at each of the screen end points and respective end point addresses of the mapping information at the intersecting point on the basis of data from the screen side generating circuit. The two end point information and the mapping information at the intersecting point on the polygonal side at each of the screen end points are clipped by the intersecting point arithmetic circuit and are written to the second polygonal end point memory.

摘要： The current methods and systems sort three-dimensional data with a reduced number of buffer memories at an increased speed. Based upon the Z-dimension data, the three-dimensional data is sorted in ascending order via two intermediate tables. Since a first intermediate table holds only one set of unique Z values, when there is a recurrence of Z values, a second intermediate table holds these multiply occurring data. At the end, the contents of these intermediate tables are merged into a single result holding table.

摘要： A polygon extracting unit divides a screen image into n-level hierarchy in a scan-line shifting direction. The polygon extracting unit then accesses the sort memory and then reads data, from the screen memory, concerning the end points of the polygon corresponding to the value obtained as a result of the sort memory access. Then, the same unit, in the highest-level regions of the hierarchy, extracts the polygon edge-pairs overlapping the highest-level region. Then, the same unit, based on polygon edge-information, calculates the information concerning the corresponding edge pair to appear on the scan line. A polygon-edge-pair memory stores data concerning the starting point and ending point of the polygon on the scan line. A transfer unit determines whether or not the extracted polygon edge-pair overlaps with the relevant region. The same unit then transfers the polygon edge-pair to the lower-level regions if the polygon edge-pair overlaps. A polygon-edge-pair data transfer unit, in the lowest-level region, determines whether or not the polygon edge-pair overlaps with the lowest-level region. The same unit then transfers a parameter required for vertical interpolation from the polygon-edge-pair memory, for the polygon edge-pair, if the polygon edge-pair overlaps. A vertical-interpolation operation unit calculates the gradient of the relevant polygon edge-pair based on the relevant data. The same unit then calculates so as to interpolate between the right crossing point and the left crossing point on the scan line. An output unit outputs dot data synchronized to the scan line associated with display unit for displaying the relevant polygon figure.
