The Displace
function shifts the texture's rows and columns according to a specified
outline.
This outline is given by the Transformation
type. When the texture's rows get shifted, a pixel's vertical
coordinate is used as Input value, the displacement
amplitude is controlled by the Output of this
transformation. The same applies to the displacement of the
columns, with the difference that a pixel's horizontal coordinate
defines the function Input there.
Image 3 for example shows the Quantize
transformation type, which results in a stairs-like shifting
pattern.
Whether the shifting should
affect the texture horizontally, vertically or in both direction,
can be defined by the Dimensions controls.
The Tiling values
regulate the repetitions of the transformation pattern along the
rows and columns.
Relative to the texture's width
and height, the amplitude of the displacement can be manipulated
with the Amplify value.
