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.

Patterns

3D Stack Selection

Choosing the right 3D approach

When to use: When starting a 3D web project

3D Stack Selection

Options Comparison

Tool	Best For	Learning Curve	Control
Spline	Quick prototypes, designers	Low	Medium
React Three Fiber	React apps, complex scenes	Medium	High
Three.js vanilla	Max control, non-React	High	Maximum
Babylon.js	Games, heavy 3D	High	Maximum

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';
import { Suspense } from 'react';

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

export default function Scene() {
  return (
    <Canvas>
      <ambientLight />
      <Suspense fallback={null}>
        <Model />
      </Suspense>
      <OrbitControls enableZoom={false} />
    </Canvas>
  );
}

3D Model Pipeline

Getting models web-ready

When to use: When preparing 3D assets

3D Model Pipeline

Format Selection

Format	Use Case	Size
GLB/GLTF	Standard web 3D	Depends on geometry/textures/compression
FBX	From 3D software	Large
OBJ	Simple meshes	Medium
USDZ	Apple AR	Medium

Optimization Pipeline

1. Model in Blender/etc
2. Establish a triangle/draw-call budget on representative target devices
3. Bake textures (combine materials)
4. Export as GLB
5. Compress with gltf-transform
6. Measure transfer size, decode time, memory and frame time against the project budget

GLTF Compression

# Use the reviewed version already pinned in the project lockfile.
# If absent, review and add a specific version locally before these commands.

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

Loading in R3F

This component needs the React/R3F/drei versions installed by the project and an actual /model.glb asset. Add an application error boundary for failed asset loads.

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

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

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

export default function Scene() {
  return (
    <Canvas>
      <ambientLight />
      <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 { Canvas, useFrame } from '@react-three/fiber';
import { useRef } from 'react';

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

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

  return (
    <mesh ref={ref}>
      <boxGeometry args={[1, 1, 1]} />
      <meshNormalMaterial />
    </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.registerPlugin(ScrollTrigger);
