constructor

new SMAAWeightsMaterial(texelSize?, resolution?): SMAAWeightsMaterial
Constructs a new SMAA weights material.
Parameters
- OptionaltexelSize: Vector2
  The absolute screen texel size.
- Optionalresolution: Vector2
  The resolution.
Returns SMAAWeightsMaterial
Overrides ShaderMaterial.constructor

Properties

alphaHash

alphaHash: boolean

Enables alpha hashed transparency, an alternative to .transparent or .alphaTest. The material will not be rendered if opacity is lower than a random threshold. Randomization introduces some grain or noise, but approximates alpha blending without the associated problems of sorting. Using TAARenderPass can reduce the resulting noise.

alphaToCoverage

alphaToCoverage: boolean

Enables alpha to coverage. Can only be used with MSAA-enabled rendering contexts (meaning when the renderer was created with antialias parameter set to true). Enabling this will smooth aliasing on clip plane edges and alphaTest-clipped edges.

Default

false

blendAlpha

blendAlpha: number

Represents the alpha value of the constant blend color. This property has only an effect when using custom blending with ConstantAlphaFactor or OneMinusConstantAlphaFactor.

Default

Represent the RGB values of the constant blend color. This property has only an effect when using custom blending with ConstantColorFactor or OneMinusConstantColorFactor.
