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>
