摘要： Perspective transformation is performed on X, Y, Z coordinate data Xe, Ye and Ze in a view volume in a viewpoint coordinate system so as to obtain X, Y, Z coordinate data Xs, Ys and Zs in a screen coordinate system. The view volume being defined by a front clipping plane and a rear clipping plane, in which: Zs=1-CZF/Ze, or Zs=CZF/Ze, or Zs=1/Ze when a difference between a Z value CZF at the front clipping plane and a Z value CZB at the rear clipping plane is substantially large. Data bits of the Zs are shifted depending on the Z value CZF, when the difference between the Z value CZF at the front clipping plane and the Z value CZB at the rear clipping plane is substantially large where the view volume is defined by the front clipping plane and the rear clipping plane, or when the view volume is defined only by the front clipping plane. Then, a hidden-surface removal operation is performed using a Z-buffer method in accordance with the Zs.

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.
