  • Patent number: 7403202
    Abstract: Embodiments of the present invention provide methods and apparatus wherein physics models are integrated with motion capture animation to allow for variability in animations, dynamic response, such as animating events different from those for which motion capture data was obtained, including changes in character purpose and collisions. The physical model may include sets of internal forces and/or external forces. To facilitate the integration of mo-cap animation data with physics models, mo-cap animation data is played back using forces on physical models rather than directly setting joint angles or positions in a graphical skeleton, which allows the animation to be dynamically altered in real-time in a physically realistic manner by external forces and impulses.

  • Patent number: 7382374
    Abstract: In a visualization system a three-dimensional scene (43) is projected onto a camera's view projection plane (42) from a camera's defined viewpoint (41) and mapped onto a two-dimensional display. For positioning a pointer (45) in the three-dimensional scene (43), the view of the three-dimensional scene is animated automatically to provide to a user the view of the three-dimensional scene with a kinetic depth effect. The view of the three-dimensional scene is animated by applying a spatial transformation to the three-dimensional scene (43) or the camera. The transformation is applied to the three-dimensional (43) scene or the camera such that the projected view of the pointer (45) remains essentially static. The pointer (45) is positioned based on signals received from the user, while the view is animated.

  • Publication number: 20020008703
    Abstract: An animation system provides synchronization services to synchronize actions of two more interactive user interface characters that are displayed simultaneously. The animation services allow applications to make animation requests to control the actions of characters on the display. These actions include playing one of the character's animation sequences and generating speech output with lip-synched animation of the character's mouth. Accessible via script commands or an Application Programming Interface, the synchronization services allow an application to control interaction between two or more characters on the display. Applications can synchronize actions by invoking straightforward commands such as Wait, Interrupt, or Stop. In response to these commands, the animation server synchronizes scheduled actions by halting playback of a character until a specified action of another character completes or halting a specified action of one character after scheduled actions for another character are completed.
