What problem does it solve? Starting a 3D/WebGL website from scratch involves many decisions and boilerplate: choosing a framework, installing the right Three.js ecosystem packages, and wiring up a working scene. This Skill automates that setup so you get a running 3D scene skeleton in minutes. ## Core Features & Use Cases - Framework Choice: Scaffolds either a Vite SPA (default, for pure 3D experiences) or a Next.js app (when SEO/SSR matters). - Quality Presets: Installs a lite core stack (three, @react-three/fiber, drei) or a full preset adding postprocessing, Rapier physics, GSAP, Lenis, zustand, and leva. - Scene Skeleton: Creates a ready-to-run project structure with a <Canvas> wrapper, lights, environment, orbit controls, and a rotating shadow-casting mesh. - Use Case: You want to build a portfolio site with an interactive 3D hero. Run this Skill to get a Vite + R3F project with a working scene, then hand off to specialized agents for shaders, motion, and asset pipelines. ## Quick Start Scaffold a new full-preset 3D website project using Vite and React Three Fiber and verify it renders in the dev server.
