What problem does it solve? Adding 3D content to websites involves hard choices about tooling, model optimization, scroll integration, and performance budgets, and mistakes lead to slow pages or broken mobile experiences. ## Core Features & Use Cases - 3D Stack Selection: Decision trees comparing Spline, React Three Fiber, vanilla Three.js, and Babylon.js so you pick the right tool for your project. - Model Pipeline & Optimization: Guidance on GLB/GLTF formats, gltf-transform compression with Draco, and performance targets per device class. - Scroll-Driven 3D & Fallbacks: Patterns for ScrollControls, GSAP camera animation, WebGL detection, and static image fallbacks. - Use Case: Build a product configurator where users rotate a 3D model, swap colors and variants, and the scene stays at 60fps on desktop and degrades gracefully on mobile. ## Quick Start Ask the AI to set up a React Three Fiber scene that loads a compressed GLB product model with orbit controls, a loading indicator, and a mobile fallback image.
