Refraction
Creates a glass-distortion effect on an image, with an optional height map. This filter causes
rasterization in 3D groups. For more information on rasterization, see
Groups and rasterization on
page 1045.
Original image Refraction filter applied (using a height map)
Parameters in the Inspector
•
Softness: Sets the amount of softness applied to the refracted edges.
•
Refraction: Sets the amount that the image is distorted.
•
Height Map: Displays a thumbnail of the height map chosen. The height map is used to
determine the edges along which the image is refracted. To learn how to add an object to the
Height Map well, see
Source well on page 132.
•
Map Channel: Sets the channel used to determine how the image is refracted. If a height map
is present, the channel is selected from the height map; otherwise the channel is selected from
the source object. Values can be selected from the following: Luminance (default), Red, Green,
Blue, or Alpha.
•
Mix: Sets the percentage of the original image to be blended with the distorted image.
Ring Lens
Creates a ring of distortion over the image, creating a donut-like bulge. This filter causes
rasterization in 3D groups. For more information on rasterization, see
Groups and rasterization on
page 1045.
Original image Ring Lens filter applied
Parameters in the Inspector
•
Center: Sets the position of the center of the lens. Drag the Center onscreen control to adjust
its value in the Canvas.
•
Radius: Sets the radius of the ring. Drag the inner circle of the onscreen controls to adjust the
Radius value in the Canvas. Drag between the inner and outer circles to adjust the Radius and
Thickness parameters simultaneously.
