    摘要: An image processing apparatus has a three-dimensional joint position storing circuit for storing a three-dimensional coordinate position for each of available joints of an object at each frame for a standard action; a geometric data storing circuit for storing geometric data for at least a portion of the object based on unique coordinate systems for each of the available joints; a unique coordinate system determining circuit for determining the unique coordinate system for each of the available joints based on the stored three-dimensional coordinate positions; a three-dimensional joint angle computing circuit for computing a three-dimensional joint angle for at least one of the available joints based on a desired mode of action modification and the determined unique coordinate systems; a joint angle displacing circuit for displacing the three-dimensional joint angle for at least one of the available joints; a unique coordinate system generating circuit for generating the unique coordinate system for at least one of the available joints; and an action synthesizing circuit for assigning the geometric data corresponding to each of the available joints.

    摘要: A method and system for manipulating and mixing previously stored motion units for computer articulated figure animation. The motion units are combined in a weighted average. The weights give a priority to certain joint rotations of a motion unit which constitute the essence of that motion unit. The motion units can be mixed in an asynchronous fashion, with no limit on the number of motion units that can be mixed together. Phrasing control assigns a weight to each frame in a motion unit, and eases the transitions at the beginning and end of a motion unit. Frame-to-frame smoothing is also used. Fatigue of an articulated figure is simulated by the addition of a "tired" motion unit.
