Spherize effect
The Spherize effect distorts a layer by wrapping a region of the image onto a sphere. The layer's quality setting influ-
ences the Spherize effect. Best quality samples the displaced pixels to subpixel precision; Draft quality samples to the
nearest whole pixel.
This effect works with 8-bpc and 16-bpc color.
Transform effect
The Transform effect applies two-dimensional geometric transformations to a layer. This effect supplements the
transform properties available for each layer in the Timeline panel. Anchor Point, Position, Rotation, Scale, and
Opacity properties function much the same as the layer transform properties in the Timeline panel.
You can specify the shutter angle for motion blur for this layer independently of the composition's shutter angle.
(Motion blur must be enabled for the layer and for the composition for this to be relevant.)
Note: This effect is relative to the input layer. Therefore, to make a layer rotate around the upper left corner, open the
layer in the Layer panel, choose Transform from the Layer panel menu, and then move the anchor point and the position
to the upper left corner.
This effect works with 8-bpc and 16-bpc color.

Skew

Turbulent Displace effect
The Turbulent Displace effect uses fractal noise to create turbulent distortions in an image. For example, use it to
create flowing water, funhouse mirrors, and waving flags.
This effect works with 8-bpc, 16-bpc, and 32-bpc color.
The type of turbulence used. Turbulent Smoother, Bulge Smoother, and Twist Smoother each
Displacement
perform the same operations as Turbulent, Bulge, and Twist, except that the Smoother options create smoother
warps and take longer to render. Vertical Displacement warps the image vertically only. Horizontal Displacement
warps the image horizontally only. Cross Displacement warps the image both vertically and horizontally.
Higher values cause more distortion.
Amount
Higher values cause larger areas of distortion.
Size
Determines the portion of the fractal shape that is used to create the distortion.
Offset (Turbulence)
Determines the level of detail in the turbulence. Lower values cause smoother distortions.
Complexity
Animating this setting results in changes of the turbulence over time.
Evolution
Note: Although the Evolution value is set in units called revolutions, it's important to realize that these revolutions are
progressive. The Evolution state continues to progress infinitely at each new value. Use the Cycle Evolution option to
return the Evolution setting to its original state at each revolution.
