Abstract:
1. An apparatus for subdividing rotation among three dimensional structures along a path in a three dimensional model, wherein each three dimensional structure is associated with an intermediate position along the path, comprising: means for receiving data defining a first pose and a second pose in three dimensions, wherein a pose is defined by at least a direction and a roll around the direction; means for receiving data defining the path associated with the first pose and the second pose; means for determining a direction for each of the intermediate positions along the path; means for determining an amount of roll around the direction at each of the intermediate positions along the path using quaternion interpolation between the roll of the first pose and the roll of the second pose; and means for applying the determined amount of roll at the intermediate positions along the path to the three dimensional structures associated with the intermediate positions.
