How to make a skybox in Three.js: A perfect guide

Description

A skybox or a cubemap is an interesting topic if you want to create a scene of nature, open ambient, a room, and so on. The skybox looks the same as an HDR image in 3D space, where you can see the 360-degree view of the area you want to simulate; the difference is that creating a cubemap or sky box is much easier and showing it in Three.js takes a different method from the HDR image background. You can also zoom in on different views when using skybox in your three.js scene. To create a Cubemap or a Skybox, we need to create a cube using the box geometry; then create six photos from the area you want to render and show in your scene. These six photos should be taken from the center’s upward, downward, left, right, front and back views. Then, they should be added to the array of material textures. This mapping should be on the backside, and the camera’s position should be limited to the area inside the cube.
