Distortion filters are used to change the shape of layers—warping, twisting, and pulling them in different directions.
There are 27 Distortion filters:
Black Hole distorts an image by causing part of it to disappear into the specified center point, bowing the top, bottom, and sides inward.
Bulge distorts an image as if forced outward by something pushing from behind.
Bump Map uses a source object to define a bump pattern that’s used to displace an image.
Disc Warp stretches the object outward around a circular region.
Droplet simulates the effect of a drop of liquid falling onto the surface of a pool.
Earthquake creates an animated displacement effect on an object.
Fisheye distorts an object as if it were seen through the view of a fisheye lens.
Flop reverses an object horizontally, vertically, or in both directions.
Fun House simulates the distortion caused by an imperfectly shaped mirror, similar to those in a carnival fun house.
Glass Block cuts an object into a series of tiles, creating a duplicated pattern effect.
Glass Distortion simulates the effect of the object being deformed as it shows through a piece of glass.
Insect Eye maps a repeating hexagonal distortion pattern to an image, mimicking the POV of an insect.
Mirror splits an object in half vertically and reverses the remaining half to create a reflection.
Page Curl animates an object as if it is a page peeling away.
Poke distorts an object by bowing the edges inward.
Polar converts images from rectangular coordinates to polar coordinates, and vice versa.
Refraction creates a glass-distortion effect on an image.
Ring Lens creates a ring of distortion over the image, creating a donut-like bulge.
Ripple creates animated ripples over the surface of an object.
Scrape smears an image along an angle.
Sphere simulates the effect of an image wrapped around a sphere.
Starburst radiates solid-colored rays out from the center of your layer.
Stripes turns an image into a series of vertical stripes.
Target draws bands of concentric circles outward from the center point value.
Twirl twirls an image like a fork twisting a plate of spaghetti.
Underwater applies an animated distortion to an image, simulating a view through water.
Wave distorts an image to simulate waves oscillating across it.
