The camera isn't placed within the three.js Skybox

I'm currently working on a 3D solar system project that involves a rocket orbiting around a planet. I attempted to follow this tutorial (https://www.youtube.com/watch?v=7fJgVyq0OYo) to create a skybox for my planets to exist within. Although no errors are displayed, and the skybox is being created, it is not positioned close to where my planets and rocket are located. I'm unsure of how to adjust my camera's starting position to be at the center of the scene. Here is the code snippet,

//code snippet here

The Code snippet above will not display as "SceneUtils.js" seems to be incompatible. My project may have been developed using an older version of Three.js since it was created in a default project template (required for an assignment). When running the project locally on my machine, it works fine. Is there a way I can properly link the script so others can view the project?

---------------------EDIT-----------------------------------

Upon further investigation, I suspect the issue might lie with how I am rendering the scene. It appears that the skybox I generated was too large, causing parts of it to vanish when viewed from certain angles. Adjusting the size helped partially, but some sections still seem to disappear during rendering.

Answer №1

Forget about that complicated tutorial suggesting unnecessary steps. Three.js actually provides a much simpler way to create a skybox using the built-in CubeTextureLoader:

    var r = "https://threejs.org/examples/textures/cube/Park3Med/";

    var urls = [
        r + "px.jpg", 
        r + "nx.jpg",
        r + "py.jpg", 
        r + "ny.jpg",
        r + "pz.jpg", 
        r + "nz.jpg"
    ];

    var textureCube = new THREE.CubeTextureLoader().load( urls );
    scene.background = textureCube;

Using this method, you won't have to worry about adjusting your camera's position manually. It will always be at the center of the cube, regardless of where your camera moves.

After reviewing your changes, it appears that the issue lies with the settings of your camera frustum. The problem seems to be related to how far objects can be from the camera and still be visible in the rendering. Certain elements of your skybox are not within the range of the far viewing plane, causing them to be truncated and resulting in the white background showing up in your scene. To resolve this, you should adjust the far frustum value to a minimum of 1000 when initializing your camera:

var camera = new THREE.PerspectiveCamera(45, window.innerWidth / window.innerHeight, 0.1, 3000);
