Three.js Landing Page Boilerplate Resources

While there isn't a specific boilerplate in the Three.js documentation that includes all the features you're looking for, I can point you to several resources and components that you can combine to create your desired landing page.

Core Components

Background 3D Model

For loading and displaying 3D models, you'll want to use:

• GLTFLoader - For loading glTF format models, which is the recommended format for Three.js

Scroll-Triggered Carousel

For scroll-based animations, you can use:

• ScrollControls from React Three Fiber's drei library (if using React)
• Or implement custom scroll detection with Intersection Observer API

Cursor Effects

For cursor effects similar to Lusion Labs, you'll need to implement custom shaders and mouse tracking.

Implementation Approach

1. Start with a basic Three.js setup (scene, camera, renderer)
2. Add a GLTF model as your background
3. Implement scroll detection to trigger animations
4. Create custom shaders for cursor effects
5. Optimize performance with techniques like instancing and proper disposal

Here's a simplified starting point:

JAVASCRIPTCopied
import * as THREE from 'three';
import { GLTFLoader } from 'three/examples/jsm/loaders/GLTFLoader.js';
import { OrbitControls } from 'three/examples/jsm/controls/OrbitControls.js';

// Setup
const scene = new THREE.Scene();
const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
const renderer = new THREE.WebGLRenderer({ antialias: true });
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);

// Controls
const controls = new OrbitControls(camera, renderer.domElement);

// Lighting
const ambientLight = new THREE.AmbientLight(0xffffff, 0.5);
scene.add(ambientLight);
const directionalLight = new THREE.DirectionalLight(0xffffff, 1);
directionalLight.position.set(5, 5, 5);
scene.add(directionalLight);

// Load background model
const loader = new GLTFLoader();
loader.load('path/to/your/model.glb', (gltf) => {
  scene.add(gltf.scene);
});

// Cursor effects
const mouse = new THREE.Vector2();
window.addEventListener('mousemove', (event) => {
  mouse.x = (event.clientX / window.innerWidth) * 2 - 1;
  mouse.y = -(event.clientY / window.innerHeight) * 2 + 1;
  
  // Update cursor effects here
});

// Scroll detection
window.addEventListener('scroll', () => {
  const scrollY = window.scrollY;
  // Update carousel based on scroll position
});

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

// Handle window resize
window.addEventListener('resize', () => {
  camera.aspect = window.innerWidth / window.innerHeight;
  camera.updateProjectionMatrix();
  renderer.setSize(window.innerWidth, window.innerHeight);
});

For more advanced features like the cursor effects on Lusion Labs, you'll need to dive deeper into custom shaders and post-processing effects using Three.js's EffectComposer.
