  • Patent number: 7986815
    Abstract: A method of producing a locomotion animation includes calculating movement information of the objects on the basis of surrounding information of the objects and motion capture data for the subjects, and measuring a collision between the objects or between an object and an obstacle on the basis of the movement information to calculate riding motion information for the subjects. The movement information and the riding motion information are then synthesized to determine movement motion and riding animations of the objects. Therefore, the motions of locomotion can be naturally connected with each other.

  • Publication number: 20110148870
    Abstract: Disclosed herein is a method and apparatus for generating graphic tentacle motions. In the method, a 3D tentacle is divided into a 1D center line and a 2D surface based on information about an initial mesh of the 3D tentacle. New locations of sample points of the center line in a new frame are determined from initial locations of sample points of the center line, based on a tentacle root motion. New locations of sample points of the surface in the new frame are determined from initial locations of sample points of the surface, based on both the initial locations of the center line sample points and the tentacle root motion. The surface is coupled to the center line using the locations of the sample points of both the center line and the surface in the new frame.
