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

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
