class: DisplacementFilter


The DisplacementFilter class uses the pixel values from the specified texture
(called the displacement map) to perform a displacement of an object. You can
use this filter to apply all manor of crazy warping effects. Currently the r
property of the texture is used to offset the x and the g property of the texture
is used to offset the y.

Extends:

GLShaderShaderFilter → DisplacementFilter

Properties


Name Type Attribute Description
vertexSrc string public

The vertex shader.

fragmentSrc string public

The fragment shader.

uniforms object public

An object containing the current values of custom uniforms.

padding number public

The padding of the filter. Some filters require extra space to breath such as a blur.
Increasing this will add extra width and height to the bounds of the object that the
filter is applied to.

resolution number public

The resolution of the filter. Setting this to be lower will lower the quality but
increase the performance of the filter.

enabled boolean public

If enabled is true the filter is applied, if false it will not.

autoFit boolean public

If enabled, pixi will fit the filter area into boundaries for better performance.
Switch it off if it does not work for specific shader.
