This simple tutorial shows how to remap an image using the uv_coords attribute of the image shader to produce an abstract patterned distortion effect.

A scene file can be downloaded here. Further examples can be found here.

• Start by assigning a standard_surface shader to a poly plane.
• Increase the emission of the standard_surface to 1. Decrease the base_weight and specular_weight to 0.
• Connect an image shader to the emission_color and add a file texture to the image_name. In this case, we have used the beautiful Mona Lisa.

• Connect a utility shader with shade_mode.flat and color_mode.uv (via an add shader) connected to the image shaders uv_coords.
• Add a noise shader as an offset to the input 2 of the add shader.

You can also add a uv_transform shader after the image for extra controls. You could also add a range shader to further control the distortion effect.

Image: UV Coordinates

In the uv_coordinates of the image shader, there are controls for further changing the position of the texture map. When animated, this can produce some interesting results:

offset_u	offset_v

• Animating the exposure (using a color_correct) connected to the texture used to distort the image shader will produce the final result.
