What problem does it solve?
This skill provides a clear, repeatable approach to setting up Three.js scenes, including scene creation, camera configuration, renderer setup, and basic object hierarchies.
Core Features & Use Cases
- Scene & Camera Setup: Quickly initialize a scene, perspective/orthographic cameras, and a WebGL renderer.
- Object Hierarchy & Transforms: Manage Object3D hierarchies, local/global transforms, and coordinate systems for consistent animation.
- Practical Examples: Build interactive 3D demos, such as rotating cubes, lighting, and responsive rendering.
Quick Start
Copy the following basic Three.js setup to create a scene with a rotating cube:
import * as THREE from 'three';
const scene = new THREE.Scene();
const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
const renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);
const geometry = new THREE.BoxGeometry();
const material = new THREE.MeshBasicMaterial({ color: 0x00ff00 });
const cube = new THREE.Mesh(geometry, material);
scene.add(cube);
camera.position.z = 5;
function animate() {
requestAnimationFrame(animate);
cube.rotation.x += 0.01;
cube.rotation.y += 0.01;
renderer.render(scene, camera);
}
animate();
