Système solaire avec Three.js

Salut ! Aujourd'hui, je vais construire un système solaire en utilisant Three.js. Mais avant de commencer, sachez que l'inspiration de cet article est venue du représentant d'un client dont je travaille actuellement sur le projet. Oui, c'est vous, celui qui croit que la Terre est plate.

JavaScript/Node possède le plus grand écosystème de bibliothèques qui couvrent une énorme quantité de fonctionnalités qui simplifient votre développement, je peux donc toujours choisir celle qui convient le mieux à vos besoins. Cependant, si nous parlons de graphiques 3D, il n'y a pas beaucoup d'options intéressantes et three.js est probablement le meilleur de tous et possède la plus grande communauté.

Alors plongeons-nous dans Three.js et construisons le système solaire en l'utilisant. Dans cet article, je couvrirai :

• Initier le projet et la scène
• Création du Soleil
• Créer des planètes
• Déploiement sur les pages GitHub

Initier le projet et la scène

Tout d'abord : pour initialiser le projet, j'utilise Vite et j'installe la dépendance Three.js. Maintenant, la question est de savoir comment configurer Three.js. Pour cela, vous aurez besoin de trois choses : une scène, une caméra et un moteur de rendu. J'utilise également le module complémentaire intégré, OrbitControls, qui me permet de naviguer dans la scène. Après avoir démarré l'application, un écran noir devrait apparaître.

import { Scene, WebGLRenderer, PerspectiveCamera } from "three";
import { OrbitControls } from "three/addons/controls/OrbitControls.js";

const w = window.innerWidth;
const h = window.innerHeight;

const scene = new Scene();
const camera = new PerspectiveCamera(75, w / h, 0.1, 100);
const renderer = new WebGLRenderer();
const controls = new OrbitControls(camera, renderer.domElement);

controls.minDistance = 10;
controls.maxDistance = 60;
camera.position.set(30 * Math.cos(Math.PI / 6), 30 * Math.sin(Math.PI / 6), 40);

renderer.setSize(w, h);
document.body.appendChild(renderer.domElement);

renderer.render(scene, camera);

window.addEventListener("resize", () => {
  const w = window.innerWidth;
  const h = window.innerHeight;
  renderer.setSize(w, h);
  camera.aspect = w / h;
  camera.updateProjectionMatrix();
});

const animate = () => {
  requestAnimationFrame(animate);
  controls.update();
  renderer.render(scene, camera);
};

animate();

Vous remarquerez peut-être que je limite le zoom via les commandes et que je modifie également l'angle par défaut de la caméra. Cela sera utile pour afficher correctement la scène dans les prochaines étapes.

Il est maintenant temps d'ajouter un simple champ d'étoiles puisque notre système solaire devrait être entouré d'étoiles. Pour simplifier l’explication, imaginez que vous avez une sphère et que vous choisissez 1 000 points aléatoires sur cette sphère. Ensuite, vous créez des étoiles à partir de ces points en leur appliquant une texture d'étoile. Enfin, j'ajoute une animation pour faire tourner tous ces points autour de l'axe y. Avec cela, le champ d'étoiles est prêt à être ajouté à la scène.

import {
  Group,
  Color,
  Points,
  Vector3,
  TextureLoader,
  PointsMaterial,
  BufferGeometry,
  AdditiveBlending,
  Float32BufferAttribute,
} from "three";

export class Starfield {
  group;
  loader;
  animate;

  constructor({ numStars = 1000 } = {}) {
    this.numStars = numStars;

    this.group = new Group();
    this.loader = new TextureLoader();

    this.createStarfield();

    this.animate = this.createAnimateFunction();
    this.animate();
  }

  createStarfield() {
    let col;
    const verts = [];
    const colors = [];
    const positions = [];

    for (let i = 0; i < this.numStars; i += 1) {
      let p = this.getRandomSpherePoint();
      const { pos, hue } = p;
      positions.push(p);
      col = new Color().setHSL(hue, 0.2, Math.random());
      verts.push(pos.x, pos.y, pos.z);
      colors.push(col.r, col.g, col.b);
    }

    const geo = new BufferGeometry();
    geo.setAttribute("position", new Float32BufferAttribute(verts, 3));
    geo.setAttribute("color", new Float32BufferAttribute(colors, 3));
    const mat = new PointsMaterial({
      size: 0.2,
      alphaTest: 0.5,
      transparent: true,
      vertexColors: true,
      blending: AdditiveBlending,
      map: this.loader.load("/solar-system-threejs/assets/circle.png"),
    });
    const points = new Points(geo, mat);
    this.group.add(points);
  }

  getRandomSpherePoint() {
    const radius = Math.random() * 25 + 25;
    const u = Math.random();
    const v = Math.random();
    const theta = 2 * Math.PI * u;
    const phi = Math.acos(2 * v - 1);
    let x = radius * Math.sin(phi) * Math.cos(theta);
    let y = radius * Math.sin(phi) * Math.sin(theta);
    let z = radius * Math.cos(phi);

    return {
      pos: new Vector3(x, y, z),
      hue: 0.6,
      minDist: radius,
    };
  }

  createAnimateFunction() {
    return () => {
      requestAnimationFrame(this.animate);
      this.group.rotation.y += 0.00005;
    };
  }

  getStarfield() {
    return this.group;
  }
}

L'ajout du champ d'étoiles est simple, simplement en utilisant la méthode add dans la classe de scène

const starfield = new Starfield().getStarfield();
scene.add(starfield);

En ce qui concerne les textures, vous pouvez retrouver toutes les textures utilisées dans ce projet dans le référentiel, dont le lien est lié à la fin de l'article. La plupart des textures ont été tirées de ce site, à l'exception des textures des anneaux d'étoiles et de planètes.

Création du soleil

Pour le soleil, j'ai utilisé la géométrie de l'icosaèdre et y ai mappé une texture. En utilisant le bruit amélioré, j'ai obtenu un effet où le soleil pulse, simulant la façon dont une vraie étoile émet des flux d'énergie dans l'espace. Le soleil n'est pas seulement une figure avec une texture cartographiée ; il doit également s'agir d'une source de lumière dans la scène, j'utilise donc PointLight pour simuler cela.

Créer des planètes

Toutes les planètes sont construites selon une logique similaire : chaque planète a besoin d'une orbite, d'une texture, d'une vitesse d'orbite et d'une vitesse de rotation. Pour les planètes qui en ont besoin, des anneaux doivent également être ajoutés.

    planetRotationDirection: "counterclockwise",
    planetTexture: "/solar-system-threejs/assets/neptune-map.jpg",
    rimHex: 0x5c7ed7,
  },
];

planets.forEach((item) => {
  const planet = new Planet(item).getPlanet();
  scene.add(planet);
});

const earth = new Earth({
  orbitSpeed: 0.00029,
  orbitRadius: 16,
  orbitRotationDirection: "clockwise",
  planetSize: 0.5,
  planetAngle: (-23.4 * Math.PI) / 180,
  planetRotationSpeed: 0.01,
  planetRotationDirection: "counterclockwise",
  planetTexture: "/solar-system-threejs/assets/earth-map-1.jpg",
}).getPlanet();

scene.add(earth);

In result all solar system will look sth like:

Deploying to GitHub Pages

For deploying to set the correct base in vite.config.js.

If you are deploying to https://.github.io/, or to a custom domain through GitHub Pages, set base to '/'. Alternatively, you can remove base from the configuration, as it defaults to '/'.

If you are deploying to https://.github.io// (eg. your repository is at https://github.com//), then set base to '//'.

Go to your GitHub Pages configuration in the repository settings page and choose the source of deployment as "GitHub Actions", this will lead you to create a workflow that builds and deploys your project, a sample workflow that installs dependencies and builds using npm is provided:

# Simple workflow for deploying static content to GitHub Pages
name: Deploy static content to Pages

on:
  # Runs on pushes targeting the default branch
  push:
    branches: ['main']

  # Allows you to run this workflow manually from the Actions tab
  workflow_dispatch:

# Sets the GITHUB_TOKEN permissions to allow deployment to GitHub Pages
permissions:
  contents: read
  pages: write
  id-token: write

# Allow one concurrent deployment
concurrency:
  group: 'pages'
  cancel-in-progress: true

jobs:
  # Single deploy job since we're just deploying
  deploy:
    environment:
      name: github-pages
      url: ${{ steps.deployment.outputs.page_url }}
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v4
      - name: Set up Node
        uses: actions/setup-node@v4
        with:
          node-version: 20
          cache: 'npm'
      - name: Install dependencies
        run: npm ci
      - name: Build
        run: npm run build
      - name: Setup Pages
        uses: actions/configure-pages@v4
      - name: Upload artifact
        uses: actions/upload-pages-artifact@v3
        with:
          # Upload dist folder
          path: './dist'
      - name: Deploy to GitHub Pages
        id: deployment
        uses: actions/deploy-pages@v4

That is it. If your deployment has not started automatically you can always start it manually in Actions tab in your repo. Link with deployed project can be found below.
