- RectAreaLight emits light uniformly across the face a rectangular plane. This light type can be
- used to simulate light sources such as bright windows or strip lighting.<br /><br />
- Important Notes:
- <ul>
- <li>There is no shadow support.</li>
- <li>Only [page:MeshStandardMaterial MeshStandardMaterial] and [page:MeshPhysicalMaterial MeshPhysicalMaterial] are supported.</li>
- <li>You have to include [link:https://threejs.org/examples/jsm/lights/RectAreaLightUniformsLib.js RectAreaLightUniformsLib] into your scene and call *init()*.</li>
- </ul>
- </p>
- <h2>Code Example</h2>
- <code>
- const width = 10;
- const height = 10;
- const intensity = 1;
- const rectLight = new THREE.RectAreaLight( 0xffffff, intensity, width, height );
- rectLight.position.set( 5, 5, 0 );
- rectLight.lookAt( 0, 0, 0 );
- scene.add( rectLight )
- const rectLightHelper = new THREE.RectAreaLightHelper( rectLight );
- rectLight.add( rectLightHelper );
- </code>

- <h2>Constructor</h2>
- <h3>[name]( [param:Integer color], [param:Float intensity], [param:Float width], [param:Float height] )</h3>
- <p>
- [page:Integer color] - (optional) hexadecimal color of the light. Default is 0xffffff (white).<br />
- [page:Float intensity] - (optional) the light's intensity, or brightness. Default is 1.<br />
- [page:Float width] - (optional) width of the light. Default is 10.<br />
- [page:Float height] - (optional) height of the light. Default is 10.<br /><br />
- Creates a new [name].

- <h2>Properties</h2>
- <p>
- See the base [page:Light Light] class for common properties.
- </p>
- <h2>Methods</h2>
- <p>
- See the base [page:Light Light] class for common methods.
- </p>
- <h3>[method:RectAreaLight copy]( [param:RectAreaLight source] )</h3>
- <p>
- Copies value of all the properties from the [page:RectAreaLight source] to this
- RectAreaLight.
