A Presentation Animation Style (0070,1A01) value of CROSSCURVE indicates that Crosscurve Animation is being specified. In this animation style, a Presentation State defines a Planar MPR view at the beginning of a curve defined in Animation Curve Sequence (0070,1A04). The Planar MPR view is stepped a distance Animation Step Size (0070,1A05) along the curve defined in Animation Curve Sequence (0070,1A04) at the rate specified by Recommended Animation Rate (0070,1A03) in steps per second. See Figure FF.3.2-3.
