@gltf-transform/extensions/dist/khr-lights-punctual/lights-punctual.d.ts

Adds extension support to @gltf-transform/core

import { Extension, ReaderContext, WriterContext } from '@gltf-transform/core';
import { Light } from './light.js';
/**
 * [`KHR_lights_punctual`](https://github.com/KhronosGroup/gltf/blob/main/extensions/2.0/Khronos/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:
 * - {@link Light}
 *
 * ### Example
 *
 * ```typescript
 * import { KHRLightsPunctual, Light, LightType } from '@gltf-transform/extensions';
 *
 * // Create an Extension attached to the Document.
 * const lightsExtension = document.createExtension(KHRLightsPunctual);
 *
 * // 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);
 * ```
