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.
const width = 10; const height = 10; const intensity = 1; const rectLight = new v3d.RectAreaLight(0xffffff, intensity, width, height); rectLight.position.set(5, 5, 0); rectLight.lookAt(0, 0, 0); scene.add(rectLight) const rectLightHelper = new v3d.RectAreaLightHelper(rectLight); rectLight.add(rectLightHelper);

color - (optional) hexadecimal color of the light. Default is 0xffffff (white).
intensity - (optional) the light's intensity, or brightness. Default is 1.
width - (optional) width of the light. Default is 10.
height - (optional) height of the light. Default is 10.
Creates a new RectAreaLight.
See the base Light class for common properties.
The light's intensity. Default is 1.
In physically correct mode, intensity is the luminance (brightness) of the light measured in nits (cd/m^2).
Changing the intensity will also change the light's power.
The light's power.
In physically correct mode, power is the luminous power of the light measured in lumens (lm).
Changing the power will also change the light's intensity.
See the base Light class for common methods.
Copies value of all the properties from the source to this RectAreaLight.
