Computes a thin-film interference effect on six spectral bands.
The color that will be perturbed by the interference effect.
The index of refraction of the thin film. We assume the exterior medium is air.
The index of refraction's amount of variation across the color spectrum.
The thickness of the thin film in nanometers.
Connect a pattern here to modulate the thickness. This will multiply the thickness value.
Compute only interference on front-facing points. By default, both sides are computed.
The color result.
The R channel from the resultRGB output.
The G channel from the resultRGB output.
The B channel from the resultRGB output.
