KHR_lights_punctual defines three "punctual" light types: directional, point and spot.

Punctual lights are parameterized, infinitely small points that emit light in well-defined directions and intensities. Lights are referenced by nodes and inherit the transform of that node.

Properties:

• Light

Example

import { LightsPunctual, Light, LightType } from '@gltf-transform/extensions';

// Create an Extension attached to the Document.
const lightsExtension = document.createExtension(LightsPunctual);

// Create a Light property.
const light = lightsExtension.createLight()
    .setType(LightType.POINT)
    .setIntensity(2.0)
    .setColor([1.0, 0.0, 0.0]);

// Attach the property to a Material.
node.setExtension('KHR_lights_punctual', light);
