GPU effects

Page Curl effect

Use Page Curl to simulate a page slowly turning. As the "page" turns, you see the back of the image mapped to the
opposite side of the curl. The back of the image is actually a mirror image of the front. This effect is most useful as a
transition where you would like to have a high-quality, textured page peel effect to reveal an underlying frame. Page
Curl includes controls that function identically to the controls in the Ripple Effect (Circular).
Page Curl adds the following controls not in the Ripple Effect (Circular):
Specifies where on the image edge the curl begins.
Angle Of Curl
Specifies how far into the image that the curl extends.
Curl Amount

Refraction effect

Use this effect to create a ripple and add a refractive look to the surface of your image. This simulates how an object
distorts when it is just beneath the surface of moving water or behind a refractive object such as frosted glass.
The Refraction effect has the following settings:
Specifies the size of the ripples. Animating this property creates the effect of moving water.
Ripple Amount
Specifies the ratio of the light's velocity as it passes from a rarer to a denser medium.
Refractive Index
Specifies the grain amount on the surface.
Bump
Specifies the depth of the surface through which you are viewing the image. For example, in the case of
Depth
simulating an underwater object, adjusting this value changes how deep an object appears to be in the water.

Ripple (Circular) effect

Use Ripple (Circular) to create an effect similar to concentric ripples on the surface of water.
The Ripple (Circular) effect has the following settings:
Specify the degree of rotation on the designated Cartesian axis.
Surface Angle X and Y
Specifies the X and Y location of the ripple center. You can also change this parameter directly in the
Ripple Center
Monitor view.
Specifies the size of the ripples.
Ripple Amount
Specify angular location of light source in polar coordinates. Angle A is on the Z axis, and
Key Light Angle A and B
angle B is formed on XY plane.
Specifies the distance between the light source and the center of the ripple surface.
Light Distance
Specifies the amount of the perturbations mapped onto the ripple surface. Adjusting this option can lend a
Bump
veined or knobby appearance to the surface, depending on the value you choose.
Specifies the glossiness of the surface.
Gloss
Specifies the amount of grain or imperfections on the surface.
