Build a Stunning 3D Portfolio with React Three Fiber (Step-by-Step)

Source: Dev.to

If you want your portfolio to stand out in 2026, a flat webpage isn’t enough. 3D portfolios built with React Three Fiber are becoming the new standard for frontend developers who want to make a real impression.

In this tutorial we’ll build a minimal but impressive 3D hero section from scratch.

What We’re Building

A 3D hero section featuring:

• A rotating 3D object as the centerpiece
• Smooth camera controls
• Responsive layout
• Clean, production‑ready code

Prerequisites

• Basic React knowledge
• Node.js installed
• Familiarity with JSX

Setup

npx create-react-app my-portfolio
cd my-portfolio
npm install three @react-three/fiber @react-three/drei

Step 1: Create the Scene

Replace src/App.js with the following:

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

export default function App() {
  return (
    
      
      
      
        
          
          
        
      
      
    
  );
}

Step 2: Add Your Name Overlay

Add a simple overlay inside the outer (or directly in `App.js` if you prefer) after the:

<div className="overlay">
  <h1>Your Name</h1>
  <p>Frontend Developer</p>
</div>

Step 3: Run It

npm start

You should see a floating wireframe icosahedron with your name overlaid. Adjust the color, geometry, and text to match your personal brand.

Performance Tips

• Use Suspense with react-three/drei’s useGLTF for lazy‑loading heavy 3D assets.
• Keep polygon count low for hero sections.
• Set frameloop="demand" on <Canvas> if the scene is mostly static.

What’s Next

This is just the foundation. A production‑ready 3D portfolio also needs:

• Smooth scroll transitions between sections
• Custom shaders for unique visual effects
• Optimized asset loading (e.g., compressed textures, DRACO)
• Mobile‑responsive camera positioning

If you want to skip the setup and get a fully‑built, production‑ready version with all of these features, check out the starter kit: R3F 3D Portfolio Starter Kit. It includes animated sections, custom lighting rigs, and a clean component structure you can drop into any React project.
