What is the process for generating a cube consisting of 600 million smaller cubes on each side using ThreeJs?

I am looking to replicate a cube similar to the one found in the game Curiosity: What's Inside The Cube?. This cube consists of 600,000,000 mini-cubes per side. Unfortunately, using textures to simulate these mini-cubes is not an option as I require a visual change on a mini-cube when it is clicked.

In my attempts, I used a BoxGeometry() object with 2 faces representing a mini-cube:

    var scene = new THREE.Scene();
    var camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
    var renderer = new THREE.WebGLRenderer({
        alpha: true
    });
    renderer.setSize(window.innerWidth, window.innerHeight);
    document.body.appendChild(renderer.domElement);

    //Here lies my cube
    var geometry = new THREE.BoxGeometry(20, 20, 20, 24494, 24494, 24494);
    var material = new THREE.MeshBasicMaterial({
        color: 0xfd59d7
    });

    var cube = new THREE.Mesh(geometry, material);
    scene.add(cube);

    camera.position.z = 100;

    render();

    function render() {
        renderer.render(scene, camera);
    }

My question remains: How can I construct a cube containing 600,000,000 mini-cubes per side that could be adequately rendered on a notebook?

Answer №1

It's important to note that the idea of Curiosity displaying a cube made from 600,000,000 cubes per side is not feasible with current GPU technology. The sheer number of triangles required for such a display would far exceed the capabilities of even top-of-the-line GPUs. In reality, what is likely being displayed in Curiosity is a simplified version of a cube, with textures and clever rendering techniques used to create the illusion of a complex structure.

If each face of the cube truly consisted of 600 million individual cubes, the amount of texture data required would be astronomical - far beyond what any mobile device could handle. This suggests that a system similar to Google Maps, where data is streamed and only portions of the cube are rendered at a time, may be more realistic for handling such a massive amount of information.
