Three.js is powerful but imperative. React Three Fiber makes 3D rendering declarative and composable — just like the rest of your React app. We use it across multiple production projects.
Production Use Cases
In Cygnet Design, we built an interactive product model viewer where engineering clients can rotate and inspect 3D product designs. In ForgeCadNeo, we render generated CAD models as STL previews directly in the browser. In our own portfolio, decorative 3D scenes add visual depth without being gimmicky.
Performance Considerations
Three.js adds approximately 600KB to your bundle. We mitigate this with React.lazy and dynamic imports — the 3D Canvas only loads when it enters the viewport. On mobile, we reduce polygon counts and disable anti-aliasing. Draw calls stay under 100 for smooth 60fps rendering.
Drei Utilities We Rely On
OrbitControls for mouse and touch rotation with damping. Stage for instant professional lighting setup without manual light placement. Html for embedding DOM elements like labels and tooltips in 3D space. Environment for HDRI-based reflections that make models look realistic.
When 3D Adds Value
3D works when users need to inspect something spatial — product models, CAD files, architectural plans. It doesn't work as pure decoration on landing pages where it slows load times without improving user experience. Every 3D element should answer the question: what can the user do with this that a 2D image can't provide?
