Function getAnisotropy

getAnisotropy(
    parameters?: {
        extensionsUsed?: GLTFExtensionsUsed;
        anisotropyTexture?: ShaderTextureDescriptor;
    },
): string
Set the anisotropy (f32), anisotropyVector (vec2f), as well as alphaT (f32), anisotropyT (vec3f) and anisotropyB (vec3f) values from the material anisotropy variables, TBN matrix and eventual anisotropy texture.
Parameters
- parameters: {
  extensionsUsed?: GLTFExtensionsUsed;
  anisotropyTexture?: ShaderTextureDescriptor;
  } = {}
  Parameters used to set the anisotropy values.
  - OptionalextensionsUsed?: GLTFExtensionsUsed
    extensionsUsed to check if anisotropy is enabled.
  - OptionalanisotropyTexture?: ShaderTextureDescriptor
    Anisotropy texture descriptor (using the RGB channel) to use if any. R and G channels represent the anisotropy direction in [-1, 1] tangent, bitangent space to be rotated by the anisotropy rotation. The B channel contains strength as [0, 1] to be multiplied by the anisotropy.
Returns string
- String with the anisotropy (f32), anisotropyVector (vec2f), as well as alphaT (f32), anisotropyT (vec3f) and anisotropyB (vec3f) values set.
