  • Publication number: 20050012750
    Abstract: A subdivision level determination unit (13) in a curved surface subdivision apparatus (10) accepts an input of information about control points that define a shape of a curved surface and determines the subdivision level for the surface. Next, it sets, for a subdivision processing operation control unit (16), a control table corresponding to the determined subdivision level. The subdivision processing operation control unit (16) executes the subdivision processing while controlling a work memory unit (14) and a subdivision processing operation unit (15) based on the set control table.

  • Patent number: 6844876
    Abstract: A three-dimensional (3D) graphic generation apparatus and its generation method according to the present invention generate high quality 3D graphics from two-dimensional (2D) graphics such as characters, without requiring difficult operations. Triangulation is performed using outline data corresponding to a sequence of all points which form an outline of a 2D graphic including a 2D character or the like, and thereafter configurations of the triangles are changed using the outline segments. The generated triangles are judged whether or not they are components of the character, and triangles that have been judged as the components are spatially moved, thereby generating the top surface. Further, side surfaces are generated by connecting corresponding points, thereby generating a 3D graphic.

  • Patent number: 6650253
    Abstract: In a map display device, a surface storing unit stores surface information which defines a curved surface having a form that depends on positions of portions of a map which are to be enlarged and/or contracted. A mapping unit maps the map onto the curved surface defined by the surface information. A projecting/displaying unit projects the mapped map onto a flat virtual screen, and displays the projected image. Here, by defining the curved surface so that each part of the curved surface forms an intended angle with a line of sight in the projection, the image is displayed with desired portions enlarged and/or contracted, while maintaining connections of roads. The same effect can also be achieved by projecting the map onto a virtual screen having the form of the curved surface.

  • Publication number: 20030179204
    Abstract: An animation control unit 1 specifies shape data, hierarchical structure data, a group table, and state information. A character state calculating unit 3 obtains the specified shape data from a shape data storing unit 5, the hierarchical structure data from a hierarchical structure storing unit 4, and the group table from a table storing unit 2. The character state calculating unit 3 also obtains motion data shown in the specified state information from a motion data storing unit 6 and specifies, from the obtained motion data, motion data identified by each group number. In accordance with the obtained hierarchical structure data, the character state calculating unit 3 corrects the shape data by using the specified motion data. A three-dimensional rendering unit 7 renders the corrected shape data to generate an image, and a display unit 9 displays the generated image.

  • Patent number: 6573842
    Abstract: When a user indicates a portion of a map to be enlarged or contracted, a surface generating unit generates surfaces by gradually changing a surface from a first shape to a second shape, the first shape corresponding to a position of a map portion previously indicated and the second shape corresponding to a position of the map portion currently indicated. A mapping unit maps the map onto the generated surfaces in sequence, to obtain mapped images. A projecting/displaying unit sequentially projects the mapped images onto a flat virtual screen, and displays the projected images. Thus, the desired portion of the map can be enlarged/contracted, while maintaining connections of roads. Also, the map display can be transformed smoothly, even when the target of enlargement/contraction changes from one map portion to another according to the user's indications. This helps the user comprehend the contents of the map quickly and accurately.
