In this chapter, we covered a lot of information about the different kinds of lights that are available in Three.js. In this chapter, you learned that configuring lights, colors, and shadows is not an exact science. To get to the correct result, you should experiment with the different settings and use a dat.GUI control to fine-tune your configuration. The different lights behave in different manners. A THREE.AmbientLight
color is added to each and every color in the scene and is often used to smooth hard colors and shadows. THREE.PointLight
emits light in all directions but can't be used to create shadows. THREE.SpotLight
is a light that resembles a flashlight. It has a conical shape, can be configured to fade over distance, and is able to cast shadows. We also looked at THREE.DirectionalLight
. This light can be compared with a faraway light, such as the sun, whose light rays travel parallel to each other, the intensity of which doesn't decrease the farther away it gets from the...
