##### FF.2.4.2.5 Swivel Animation

A Presentation Animation Style (0070,1A01) value of SWIVEL indicates that Swivel Animation is being specified. In this animation style, a Presentation State defines an initial volume rendered using Viewpoint Position (0070,1603), Viewpoint LookAt Point (0070,1604) and Viewpoint Up Direction (0070,1605). When the animation begins, the view begins to rotate back and forth about an axis parallel to the Viewpoint Up Direction (0070,1605) that intersects the Viewpoint LookAt Point (0070,1604). The extent of the arc of rotation is defined by Swivel Range (0070,1A06) and the maximum rate of rotation is specified by Recommended Animation Rate (0070,1A03) in degrees per second, although it is recommended that the changes of direction at the ends of the swivel range be smooth which implies a slowing of the rotation as the endpoints are approached.
