Abstract: PURPOSE: An amorphous object animation method is provided to perform the modeling as a material point-three dimensional spring model, calculate force and torque applied to the material point, integrate the calculated value and obtain a new position and a new posture of the material point, thereby capable of modeling and animating the amorphous object intuitionally by a user. CONSTITUTION: An amorphous object models as a material point-three dimensional spring model and various spring constants are initialized(S10). For calculating expanding force and restoring force, force and torque acting to the material point are initialized(S20). Force and torque acting to the material point are cumulatively calculated(S30). Force and torque are integrated and new position and posture of the material point are calculated(S40). After calculating new position and posture of the material point, the existing values are replaced with the obtained values and updated(S50).

Abstract: PURPOSE: A method of changing a posture of an articular object in video production is provided to vary a posture of a person through a small quantity of calculations without using numerical analysis. CONSTITUTION: A user inputs the initial posture, reference points, operation points and target points of an articular object and a posture changing method(S201). It is judged if the number of joints between the reference points and operation points is more than three(S202). When the number of joints is less than two, it is judged if the posture changing method is half-segmentation or third-segmentation or a case other than the half-segmentation or third-segmentation(S204). When the posture changing method is half-segmentation or third-segmentation, the number of joints between the reference points and operation points is judged(S205). In the case that the number of joints is less than tow, the half-segmentation or third-segmentation posture change is performed(S209). When the changed posture of the object satisfies a predetermined completion condition(S213), the changed posture is displayed on a display(S214).

Abstract: PURPOSE: A walking-motion transformation animation method is provided to make a real time realization by modifying route position and direction after changing walking-motion data to be circulated. CONSTITUTION: A walking-motion transformation stage is composed of an initialization stage(301), a leg length adjusting stage(302), a walking width adjusting stage(303), a static kinematics calculation stage(304), and a route position and direction correction stage(305). The initialization stage(301) initializes a leg length constant and a walking width constant, and receives input of walking-motion data of frame unit including Oiler's rotation angle by each frame against parent joint region coordinate of each joint region coordinate according to initial route coordinate value, foot coordinate value, body class structure. The leg length adjusting stage(302) sets up walking period and circulation motion section for continuous walking-motion and gets information about foot to be fixed on floor. The walking width adjusting stage(303) receives user's input about direction conversion, leg length and walking width. The static kinematics calculation stage(304) adjusts leg length and walking width and corrects route coordinates value and processing direction using static kinematics. The route position and direction correction stage(305) indicates human model on screen using the result of the static kinematics calculation stage(304).
