How to Make a Scroll-Driven 3D Website
Scroll-driven 3D using GSAP ScrollTrigger + Three.js — scrub camera/mesh state through timeline as user scrolls.
Making scroll-driven 3D: (1) Set up Three.js scene as usual. (2) Add GSAP + ScrollTrigger npm packages. (3) Define a master GSAP timeline with tweens for camera position, mesh transforms, material uniforms. (4) Wrap timeline in ScrollTrigger with scrub:true so scroll scrubs the timeline. (5) Add Lenis smooth scroll for polished scroll feel. (6) Test on mobile — scroll-driven sites can feel sluggish without optimization. Time: 16-40 hours for first scroll-driven build. Resources: GSAP ScrollTrigger docs, Codrops scroll-driven tutorials.
Want a faster path
If your timeline is short and the project matters commercially, hiring an experienced developer often beats self-learning by 4-6 weeks of effort. I take on How to Make a Scroll-Driven 3D Website projects on a fixed-price basis — you get the working result without the learning detour.

Further reading
Three resources I recommend after this guide: the official Three.js fundamentals docs (excellent and underused), Bruno Simon's Three.js Journey (paid, comprehensive), and the React Three Fiber docs if you'll work in React. Beyond that, reading other developers' source on GitHub — search for 'three-js portfolio' on GitHub trending — accelerates learning faster than any tutorial.
Prerequisites
Before starting on how to make scroll driven, you need: a JavaScript baseline (familiarity with ES modules, async/await, npm), a working local dev environment (Node 18+, a code editor), and a basic mental model of what WebGL renders. You don't need 3D modeling skills — for most tutorials, the assets are provided. Time investment: 2-4 hours of focused work for the basic version.
Step-by-step outline
Step 1: scaffold the project (Vite + Three.js). Step 2: get a basic scene rendering — camera, light, geometry. Step 3: load the asset (glTF). Step 4: hook up animation timeline (GSAP or built-in). Step 5: add interactivity (click, scroll). Step 6: optimize for mobile (device-tier check, asset compression). Step 7: deploy. Each step builds on the previous; skipping leads to confusion later.
