Working with Special Lights

Different types of lights

We’ve looked at the basic lights provided by Three.js and how shadows work. In most cases, we’ll use a combination of these lights for our scene. Three.js also provides a couple of special lights for very specific use cases.

In this lesson on special lights, we’ll discuss three additional lights provided by Three.js.

• First, we’ll discuss THREE.HemisphereLight, which helps in creating more natural lighting for outdoor scenes.

• Then, we’ll look at THREE.RectAreaLight, which emits lights from a large area instead of a single point.

• Next, we’ll look at how we can use a LightProbe to apply light based on a cubemap.

• Finally, we’ll show how we can add a lens flare effect to our scene.

The first special light we’re going to look at is THREE.HemisphereLight.
