  • Patent number: 7233327
    Abstract: Subdividing rotation between two poses in three dimensions may be accomplished in three parts. First, data defining the two poses is obtained from the animation or modeling interface. Second, a path associated with the two poses is determined. Third, using quaternion interpolation, the roll between the two poses is interpolated at intermediate positions along the path. The amount of roll at each of these intermediate positions then may be applied to three dimensional structures used for character rigging.
    Type: Grant

  • Patent number: 7116341
    Abstract: An information presentation apparatus creates a three-dimensional animation of a specific object in a three-dimensional virtual space on the basis of the human characteristic of paying more attention to a moving object. A user's attention can be drawn to a specific object, such as a destination building, in the virtual space displayed on the screen. Irrespective of whether the specific object is selected by the user or designated at the system side to which the user's attention is to be drawn, the user can easily detect the attention-drawing object.

  • Patent number: 6798415
    Abstract: Rendering a three-dimensional model comprised of three-dimensional data defining a bone includes obtaining a point at which the bone intersects a collision surface, determining a correction factor for use in rotating the bone from the point to a position in front of the collision surface, and rendering the three-dimensional model, including the bone, using the correction factor.
