A light source whose shape, direction, and intensity of illumination is determined by a photometric profile.

Declaration

const SCNLightType SCNLightTypeIES;

Discussion

The intensity of a photometric light varies in different directions from the light source, much like the illumination from a real-world light source. The position of the containing node determines the location of the light source, and the orientation of the node determines the relative directions specified by the photometric profile. Spotlight angle attributes do not apply to photometric lights.
