create an animated 3d cube in javascript

To create an animated 3D cube in JavaScript, we can use a library called Three.js. First, we need to include the Three.js library in our HTML file:


<script src="https://cdn.jsdelivr.net/npm/three@0.128.0/build/three.min.js"></script>
86 chars
2 lines

Then, we can create a basic scene, camera, and renderer in our JavaScript file:


index.tsx
// create a scene
const scene = new THREE.Scene();

// create a camera
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);
364 chars
12 lines

Next, we can create a cube geometry and material, and add it to the scene:


index.tsx
// create a cube geometry
const geometry = new THREE.BoxGeometry(1, 1, 1);

// create a material
const material = new THREE.MeshBasicMaterial({ color: 0xffffff });

// create a mesh using the geometry and material
const cube = new THREE.Mesh(geometry, material);

// add the mesh to the scene
scene.add(cube);

12 lines

To animate the cube, we can use a render loop that updates the cube's rotation on each frame:


index.tsx
function animate() {
  requestAnimationFrame(animate);

  // rotate the cube on each frame
  cube.rotation.x += 0.01;
  cube.rotation.y += 0.01;

  renderer.render(scene, camera);
}
animate();

This will create an animated 3D cube using Three.js. You can customize the cube's size, color, and rotation speed by adjusting the parameters in the code.
