Stack Tecnico Completo
THREE.JS / R3F SETUP
Setup minimo Three.js (Vite):
// vite.config.js
import { defineConfig } from 'vite'
export default defineConfig({ /* standard */ })
// main.js
import * as THREE from 'three'
import { OrbitControls } from 'three/examples/jsm/controls/OrbitControls'
import { GLTFLoader } from 'three/examples/jsm/loaders/GLTFLoader'
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, alpha: true })
renderer.setSize(window.innerWidth, window.innerHeight)
renderer.setPixelRatio(Math.min(window.devicePixelRatio, 2))
renderer.shadowMap.enabled = true
renderer.shadowMap.type = THREE.PCFSoftShadowMap
document.body.appendChild(renderer.domElement)
React Three Fiber (R3F) Setup:
// npm install @react-three/fiber @react-three/drei
import { Canvas } from '@react-three/fiber'
import { OrbitControls, Environment, Float, Text3D } from '@react-three/drei'
import { useFrame, useThree } from '@react-three/fiber'
import { useRef, useMemo } from 'react'
function Scene() {
return (
<Canvas
camera={{ position: [0, 0, 5], fov: 75 }}
gl={{ antialias: true, alpha: true }}
dpr={[1, 2]}
>
<Environment preset="city" />
<OrbitControls enableDamping dampingFactor={0.05} />
<MyMesh />
</Canvas>
)
}
SHADER GLSL
Vertex Shader Pattern (Onda):
// vertex.glsl
uniform float uTime;
uniform float uAmplitude;
varying vec2 vUv;
varying float vElevation;
void main() {
vUv = uv;
vec4 modelPosition = modelMatrix * vec4(position, 1.0);
float elevation = sin(modelPosition.x * 3.0 + uTime) * uAmplitude
+ sin(modelPosition.z * 2.0 + uTime * 0.8) * uAmplitude;
modelPosition.y += elevation;
vElevation = elevation;
gl_Position = projectionMatrix * viewMatrix * modelPosition;
}
Fragment Shader Pattern (Colore dinamico):
// fragment.glsl
uniform vec3 uColorLow;
uniform vec3 uColorHigh;
varying float vElevation;
void main() {
float mixStrength = (vElevation + 0.1) * 3.0;
vec3 color = mix(uColorLow, uColorHigh, mixStrength);
gl_FragColor = vec4(color, 1.0);
}
ShaderMaterial in Three.js:
const material = new THREE.ShaderMaterial({
vertexShader: vertexGLSL,
fragmentShader: fragmentGLSL,
uniforms: {
uTime: { value: 0 },
uAmplitude: { value: 0.2 },
uColorLow: { value: new THREE.Color('#ff6030') },
uColorHigh: { value: new THREE.Color('#1b3984') }
},
transparent: true
})
// In animate loop:
material.uniforms.uTime.value = clock.getElapsedTime()
GSAP ANIMAZIONI
Setup e Pattern Core:
import gsap from 'gsap'
import { ScrollTrigger } from 'gsap/ScrollTrigger'
import { ScrollSmoother } from 'gsap/ScrollSmoother' // ClubGSAP
import { SplitText } from 'gsap/SplitText' // ClubGSAP
gsap.registerPlugin(ScrollTrigger, ScrollSmoother, SplitText)
// TESTO ANIMATO (split letters)
const split = new SplitText('.heading', { type: 'chars, words' })
gsap.from(split.chars, {
opacity: 0, y: 100, rotationX: -90, stagger: 0.02,
duration: 0.8, ease: 'back.out(1.7)',
scrollTrigger: { trigger: '.heading', start: 'top 80%' }
})
// PARALLAX SEZIONE
gsap.to('.hero-bg', {
yPercent: -30,
ease: 'none',
scrollTrigger: {
trigger: '.hero',
start: 'top top',
end: 'bottom top',
scrub: true
}
})
// COUNTER ANIMATO
gsap.to('.counter', {
innerText: 9999,
snap: { innerText: 1 },
duration: 2,
ease: 'power2.out',
scrollTrigger: { trigger: '.stats', start: 'top 80%' }
})
// TIMELINE SEQUENZIALE
const tl = gsap.timeline({ scrollTrigger: { trigger: '.section', start: 'top 60%' } })
tl.from('.card', { opacity: 0, y: 60, stagger: 0.15, duration: 0.6 })
.from('.title', { opacity: 0, x: -40 }, '-=0.4')
.from('.cta', { scale: 0, ease: 'elastic.out(1, 0.5)' }, '-=0.2')
PERFORMANCE 3D
Ottimizzazioni Critiche:
// 1. Geometry merging (meno draw calls)
const merged = BufferGeometryUtils.mergeGeometries(geometries)
// 2. Instanced Mesh (1000+ oggetti identici)
const instancedMesh = new THREE.InstancedMesh(geometry, material, count)
const dummy = new THREE.Object3D()
for (let i = 0; i < count; i++) {
dummy.position.set(x, y, z)
dummy.updateMatrix()
instancedMesh.setMatrixAt(i, dummy.matrix)
}
// 3. Frustum culling: automatico, mantieni oggetti piccoli
// 4. LOD (Level of Detail)
const lod = new THREE.LOD()
lod.addLevel(highDetailMesh, 0) // vicino
lod.addLevel(medDetailMesh, 50) // medio
lod.addLevel(lowDetailMesh, 100) // lontano
// 5. Texture optimization
texture.minFilter = THREE.LinearMipmapLinearFilter
renderer.capabilities.getMaxAnisotropy() // usa max anisotropy
// 6. Dispose resources quando non servono
geometry.dispose()
material.dispose()
texture.dispose()
REACT + VITE SETUP OTTIMALE
vite.config.js:
import { defineConfig } from 'vite'
import react from '@vitejs/plugin-react'
import { visualizer } from 'rollup-plugin-visualizer'
export default defineConfig({
plugins: [react(), visualizer()],
build: {
rollupOptions: {
output: {
manualChunks: {
three: ['three'],
gsap: ['gsap'],
vendor: ['react', 'react-dom']
}
}
}
}
})
Lazy Loading 3D Components:
const ThreeScene = lazy(() => import('./ThreeScene'))
// Wrapper con Suspense + fallback skeleton
<Suspense fallback={<SceneSkeleton />}>
<ThreeScene />
</Suspense>

GSAP + THREE.JS INTEGRAZIONE
// Animare proprietà Three.js con GSAP
gsap.to(mesh.position, { x: 2, duration: 1, ease: 'power2.inOut' })
gsap.to(mesh.rotation, { y: Math.PI * 2, duration: 2, repeat: -1, ease: 'none' })
