The different lights behave in different ways and, as we’ll see in Chapter 4, materials respond differently to lights as well.

A THREE.AmbientLight color is added to every color in the scene and is often used to smooth hard colors and shadows. THREE.PointLight emits light in all directions and can cast shadows. THREE.SpotLight is a light that resembles a flashlight. It has a conical shape, can be configured to fade over distance, and can cast shadows. We also looked at THREE.DirectionalLight. This light can be compared to a faraway light, such as the Sun, whose light rays travel parallel to each other, the intensity of which doesn’...
