Twirl (PB only)

This effect twirls the pixels of an image around a specified point at a specified amount. Pixels nearer the center point are twirled faster than pixels in outer regions, resulting in a whirlpool effect. Because distortion in this effect is significant, After Effects uses special anti-aliasing techniques to produce the highest-quality image. As a result, the Twirl effect can be particularly slow to render.
