Embedding the Three.js Editor and Using a Created Scene

This tutorial will guide you on how to embed the Three.js Editor into your web application and how to use a scene created in the editor in your own Three.js project.

1. Embedding the Three.js Editor​

To embed the Three.js Editor, you can use an HTML <iframe>. This allows users to interact with the editor directly from your webpage.

Step 1: Create an HTML Page​

Create a basic HTML file to host your Three.js Editor.

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Three.js Editor</title>
    <style>
        body { margin: 0; }
        iframe { width: 100%; height: 600px; border: none; }
    </style>
</head>
<body>
    <iframe src="https://threejs.org/editor/"></iframe>
</body>
</html>

Step 2: Save and Open Your HTML File​

Save your HTML file and open it in a web browser. You will see the Three.js Editor embedded in your page.

2. Using a Created Scene​

Once you have created a scene in the Three.js Editor, you can export it and use it in your own Three.js project.

Step 1: Export the Scene​

  1. Open the Three.js Editor.
  2. Create your 3D scene using the editor.
  3. Click on the File menu in the top left corner.
  4. Select Export and then choose Export Scene to save the scene as a .json file.

Step 2: Load the Scene in Your Project​

To load the exported scene into your Three.js project, use the THREE.ObjectLoader. Here’s how you can do it:

// Create a scene and a camera
const scene = new THREE.Scene();
const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
camera.position.z = 5;

// Create a renderer
const renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);

// Load the exported scene
const loader = new THREE.ObjectLoader();
loader.load('path/to/your/exported_scene.json', (loadedScene) => {
    scene.add(loadedScene); // Add the loaded scene to the current scene
});

// Render loop
function animate() {
    requestAnimationFrame(animate);
    renderer.render(scene, camera);
}

animate();

Step 3: Ensure File Accessibility​

  • Hosting the JSON File: Make sure that your JSON file is hosted on a server and is accessible from the location where your HTML file is served.
  • Running Locally: If you are running this locally, you may need to set up a local server (like using Live Server in VSCode) to serve the file correctly.

3. Conclusion​

By following this tutorial, you have learned how to embed the Three.js Editor into your own web application and how to export and use a scene created in the editor in your Three.js projects.
