Chapter 132: PointLight

Core Idea

A light that gets emitted from a single point in all directions. A common use case for this is to replicate the light emitted from a bare lightbulb.

This light can cast shadows - see the PointLightShadow for details.

const light = new THREE.PointLight( 0xff0000, 1, 100 );
light.position.set( 50, 50, 50 );
scene.add( light );

Properties

Property	Description
`.decay : number`	The amount the light dims along the distance of the light. In context of physically-correct rendering the default value should not be changed.
`.distance : number`	When distance is zero, light will attenuate according to inverse-square law to infinite distance. When distance is non-zero, light will attenuate according to inverse-square law until near the distan…
`.isPointLight : boolean (readonly)`	This flag can be used for type testing.
`.power : number`	The light's power. Power is the luminous power of the light measured in lumens (lm). Changing the power will also change the light's intensity.
`.shadow : PointLightShadow`	This property holds the light's shadow configuration.
