In three.js there are several types of lights that we can choose from. These options exist so that we can simulate various kinds of lighting scenarios. One of the simplest light types is a point light. A point light gets emitted from a single point in space in all directions. Think of a light bulb as an example of a point light. You can add a point light to the scene by calling the PointLight() function. It can be hard to visualize the position of the lights. To solve for that issue you can add a sphere geometry under the light to see where the light currently is.

It's going to be working with a single argument…which is going to be the intensity for the PointLight.…A PointLight takes two arguments.…One of them is the color of the lights…which I will be using white color…and the second's argument is going to be the intensity…which is going to be received from the function arguments.…Now that I have this function,…I can call it inside the init function…to be able to create the PointLights…with the intensity of one…
