How to Create a rorating .glb sculpture in a webGL metaverse envoronment using the three.js library.
Creating a rotating .glb sculpture using Three.js in a webGL metaverse environment involves several steps. First, make sure you have included the Three.js library in your HTML file. You can use the following script as a starting point:
```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Three.js Sculpture</title>
<style>
body { margin: 0; }
canvas { display: block; }
</style>
</head>
<body>
<script type="module">
import * as THREE from 'https://threejsfundamentals.org/threejs/resources/threejs/r125/build/three.module.js';
import { GLTFLoader } from 'https://threejsfundamentals.org/threejs/resources/threejs/r125/examples/jsm/loaders/GLTFLoader.js';
let camera, scene, renderer;
let sculpture;
init();
animate();
function init() {
// Create a scene
scene = new THREE.Scene();
// Create a camera
camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
camera.position.z = 5;
// Create a renderer
renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);
// Load the .glb model
const loader = new GLTFLoader();
loader.load('path/to/your/sculpture.glb', (gltf) => {
sculpture = gltf.scene;
scene.add(sculpture);
});
// Add ambient light
const ambientLight = new THREE.AmbientLight(0xffffff, 0.5);
scene.add(ambientLight);
// Add directional light
const directionalLight = new THREE.DirectionalLight(0xffffff, 1);
directionalLight.position.set(1, 1, 1).normalize();
scene.add(directionalLight);
}
function animate() {
requestAnimationFrame(animate);
// Rotate the sculpture
if (sculpture) {
sculpture.rotation.x += 0.01;
sculpture.rotation.y += 0.01;
}
// Render the scene
renderer.render(scene, camera);
}
// Handle window resize
window.addEventListener('resize', () => {
const newWidth = window.innerWidth;
const newHeight = window.innerHeight;
camera.aspect = newWidth / newHeight;
camera.updateProjectionMatrix();
renderer.setSize(newWidth, newHeight);
});
</script>
</body>
</html>
```
This script creates a basic Three.js scene, loads a .glb model, adds lights, and sets up a simple animation to rotate the sculpture. Replace the `'path/to/your/sculpture.glb'` with the actual path to your .glb file.
Remember to include the Three.js library and GLTFLoader from a CDN or your local installation. Adjust the camera position, lighting, and other parameters based on your preferences and the specifics of your model.
