Learn Three.js from Scratch — Practical Path
Recommended Three.js learning path: official fundamentals, then Three.js Journey, then build a real project.
Learning Three.js from scratch: (1) Read official Three.js fundamentals docs (free, excellent) — understand Scene, Camera, Renderer, Mesh, Material, Light. (2) Take Bruno Simon's Three.js Journey course (paid, comprehensive) — covers shaders, advanced techniques, real production patterns. (3) Build a real project — portfolio, marketing site, or product showcase. (4) Read other developers' source on GitHub — search "three.js portfolio" trending. Total: 80-200 hours from zero to commercial competence, depending on pace and JavaScript baseline.
Prerequisites
Before starting on learn three js from scratch, 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.
Common pitfalls
Three failure modes I see beginners hit: (1) trying to render before assets finish loading — always wait for the loader callback, (2) using full-resolution textures on mobile — always have KTX2 or compressed alternatives, (3) leaving the scene rendering when off-screen — pause the render loop with IntersectionObserver. Each pitfall has a clear fix; the trick is recognizing the symptom.
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.
