Interface IridescenceProps

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

const material = new Material3D({ iridescence: {} });
material.iridescence!.thicknessMaximum = 600;

interface IridescenceProps {
    factor: number;
    ior: number;
    texture: Texture;
    thicknessMaximum: number;
    thicknessMinimum: number;
}

Properties

factor: number

Strength of the effect, from 0 (none) to 1

material.iridescence!.factor = 0.5;

ior: number

Index of refraction of the film

material.iridescence!.ior = 1.4;

texture: Texture

The packed map, factor in red and thickness in green

material.iridescence!.texture = await Assets.load('film.png');

thicknessMaximum: number

Film thickness in nanometres where the texture's green channel is 1

material.iridescence!.thicknessMaximum = 500;

thicknessMinimum: number

Film thickness in nanometres where the texture's green channel is 0

material.iridescence!.thicknessMinimum = 100;
