Abstract: In computer graphics, polygons constituting two polygon models are matched to realize spontaneous morphing. Each of first and second polygon models is split into corresponding parts, such as ear, eye or face, and polygons making up a part of the first polygon model are matched to polygons making up a part of the second polygon corresponding to the first-stated part. A connection relational graph, as a two-dimensional graph representing the connection relation between polygons making up the respective parts, is prepared from the two matched parts, and the connection relational graphs of the two matched parts are rendered co-morphic to match the polygons constituting the two parts.

Abstract: An IR keyboard 1 generates key code information corresponding to key operated to add break flag information indicating distinction between in-operation and operation release to the key code information as operation status information of the key to add terminator code information indicating that the key code information corresponding to key operation every once is completed to the last portion of the key code information to transmit, as key operation information, the key code information, the break flag information and the key code information by an infrared ray signal from a light emitting unit 11. Further, a light receiving unit 2 receives the infrared ray signal transmitted from the light emitting unit 11 to input key operation information of the IR keyboard 1 to a computer unit 3.
