Spherize
This effect distorts a layer by wrapping a region of the image onto a spherical shape of
variable size. The layer's quality setting influences the Spherize effect. Best quality samples
the displaced pixels to subpixel accuracy; Draft quality samples to the nearest whole pixel.
The Radius option specifies the radius of the sphere in pixels. You can exceed the highest
slider value by clicking the Radius value and typing a higher number in the dialog box.
Center of Sphere specifies the position of the sphere's center on the layer.
Transform
This effect applies 2D geometric transformations to the source layer and supplements the
transform properties available for each layer in the Timeline window. Using this effect, you
can skew a layer along any axis. Also, if motion blur is enabled, you can specify motion blur
independent of the composition's shutter angle. Anchor Point, Position, Rotation, and
Opacity function the same as the layer transform properties in the Timeline window.
Note: This effect is relative to the input layer. Therefore, to make a layer rotate around the
upper left corner, open the layer window, select Transform in the Layer window menu, and
then move the anchor point and the position to the upper left corner.

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.
For more information, see the After Effects product section on Adobe's Web site.
Wave Warp (PB only)
This effect produces the appearance of a wave traveling across an image. You can produce
a variety of different wave shapes, including square, circular, and sine waves. The Wave
Warp effect is automatically animated at a constant speed across the time range (without
keyframes). Set keyframes to vary speeds.
