Interface AnisotropyProps

Runtime controls for a material's anisotropy group, as material.anisotropy

const material = new Material3D({ metallic: 1, anisotropy: {} });
material.anisotropy!.rotation = Math.PI / 4;

interface AnisotropyProps {
    rotation: number;
    strength: number;
    texture?: Texture<TextureSource<any>>;
}

Properties

rotation: number

Rotation of the stretch direction in radians, starting from the surface's tangent

material.anisotropy!.rotation += 0.01;

strength: number

How strongly highlights stretch, from 0 to 1

material.anisotropy!.strength = 0.5;

The direction map (direction in RG, strength in B), or undefined when the material was built without one

Read-only: to add one, clone the material with anisotropy: { texture }; to swap it, assign material.textures.anisotropy.
