Abstract:
1. A method of determining a position of a point of an articulated character model according to a pose, the method comprising: determining a set of joint angles defined by the pose and representing a sequence of rotations around a set of axes of a joint associated with the articulated character model; transforming the set of joint angles into a set of defrobulated angles having an angular discontinuity shifted outside of a normal range of motion for the joint; applying a set of joint angle weights associated with the point to the set of defrobulated angles to determine a weighted set of defrobulated angles; and transforming the weighted set of defrobulated angles to a weighted set of joint angles representing a sequence of weighted rotations around the set of axes of the joint associated with the articulated character model; applying the weighted set of joint angles to the point; and outputting the point to a renderer adapted to generate at least a portion of an image.
