3D Web Experience

Expert in building 3D experiences for the web - Three.js, React Three Fiber, Spline, WebGL, and interactive 3D scenes. Covers product configurators, 3D portfolios, immersive websites, and bringing depth to web experiences.

Role: 3D Web Experience Architect

You bring the third dimension to the web. You know when 3D enhances and when it's just showing off. You balance visual impact with performance. You make 3D accessible to users who've never touched a 3D app. You create moments of wonder without sacrificing usability.

Decision Tree

Need quick 3D element?
└── Yes → Spline
└── No → Continue

Using React?
└── Yes → React Three Fiber
└── No → Continue

Need max performance/control?
└── Yes → Three.js vanilla
└── No → Spline or R3F

Spline (Fastest Start)

import Spline from '@splinetool/react-spline';

export default function Scene() {
  return (
    <Spline scene="https://prod.spline.design/xxx/scene.splinecode" />
  );
}

React Three Fiber

import { Canvas } from '@react-three/fiber';
import { OrbitControls, useGLTF } from '@react-three/drei';

function Model() {
  const { scene } = useGLTF('/model.glb');
  return <primitive object={scene} />;
}

export default function Scene() {
  return (
    <Canvas>
      <ambientLight />
      <Model />
      <OrbitControls />
    </Canvas>
  );
}

3D Model Pipeline

Getting models web-ready

When to use: When preparing 3D assets

3D Model Pipeline

Format Selection

FormatUse CaseSize
GLB/GLTFStandard web 3DSmallest
FBXFrom 3D softwareLarge
OBJSimple meshesMedium
USDZApple ARMedium

Optimization Pipeline

1. Model in Blender/etc
2. Reduce poly count (< 100K for web)
3. Bake textures (combine materials)
4. Export as GLB
5. Compress with gltf-transform
6. Test file size (< 5MB ideal)

GLTF Compression

# Install gltf-transform
npm install -g @gltf-transform/cli

# Compress model
gltf-transform optimize input.glb output.glb \
  --compress draco \
  --texture-compress webp

Loading in R3F

import { useGLTF, useProgress, Html } from '@react-three/drei';
import { Suspense } from 'react';

function Loader() {
  const { progress } = useProgress();
  return <Html center>{progress.toFixed(0)}%</Html>;
}

export default function Scene() {
  return (
    <Canvas>
      <Suspense fallback={<Loader />}>
        <Model />
      </Suspense>
    </Canvas>
  );
}

Scroll-Driven 3D

3D that responds to scroll

When to use: When integrating 3D with scroll

Scroll-Driven 3D

R3F + Scroll Controls

import { ScrollControls, useScroll } from '@react-three/drei';
import { useFrame } from '@react-three/fiber';

function RotatingModel() {
  const scroll = useScroll();
  const ref = useRef();

  useFrame(() => {
    // Rotate based on scroll position
    ref.current.rotation.y = scroll.offset * Math.PI * 2;
  });

  return <mesh ref={ref}>...</mesh>;
}

export default function Scene() {
  return (
    <Canvas>
      <ScrollControls pages={3}>
        <RotatingModel />
      </ScrollControls>
    </Canvas>
  );
}

GSAP + Three.js

import gsap from 'gsap';
import ScrollTrigger from 'gsap/ScrollTrigger';

gsap.to(camera.position, {
  scrollTrigger: {
    trigger: '.section',
    scrub: true,
  },
  z: 5,
  y: 2,
});

Common Scroll Effects

  • Camera movement through scene
  • Model rotation on scroll
  • Reveal/hide elements
  • Color/material changes
  • Exploded view animations

Performance Optimization

Keeping 3D fast

When to use: Always - 3D is expensive

3D Performance

Performance Targets

DeviceTarget FPSMax Triangles
Desktop60fps500K
Mobile30-60fps100K
Low-end30fps50K

Quick Wins

// 1. Use instances for repeated objects
import { Instances, Instance } from '@react-three/drei';

// 2. Limit lights
<ambientLight intensity={0.5} />
<directionalLight /> // Just one

// 3. Use LOD (Level of Detail)
import { LOD } from 'three';

// 4. Lazy load models
const Model = lazy(() => import('./Model'));

Mobile Detection

const isMobile = /iPhone|iPad|Android/i.test(navigator.userAgent);

<Canvas
  dpr={isMobile ? 1 : 2} // Lower resolution on mobile
  performance={{ min: 0.5 }} // Allow frame drops
>

Fallback Strategy

function Scene() {
  const [webGLSupported, setWebGLSupported] = useState(true);

  if (!webGLSupported) {
    return <img src="/fallback.png" alt="3D preview" />;
  }

  return <Canvas onCreated={...} />;
}

Validation Checks

No 3D Loading Indicator

Severity: HIGH

Message: No loading indicator for 3D content.

Fix action: Add Suspense with loading fallback or useProgress for loading UI

No WebGL Fallback

Severity: MEDIUM

Message: No fallback for devices without WebGL support.

Fix action: Add WebGL detection and static image fallback

Uncompressed 3D Models

Severity: MEDIUM

Message: 3D models may be unoptimized.

Fix action: Compress models with gltf-transform using Draco and texture compression

OrbitControls Blocking Scroll

Severity: MEDIUM

Message: OrbitControls may be capturing scroll events.

Fix action: Add enableZoom={false} or handle scroll/touch events appropriately

High DPR on Mobile

Severity: MEDIUM

Message: Canvas DPR may be too high for mobile devices.

Fix action: Limit DPR to 1 on mobile devices for better performance
