# UI useFrame

Sync UI elements outside the Canvas with the render loop using R3F v10's external useFrame.

## Technique

Since React Three Fiber v10, `useFrame` can be used outside of the Canvas component. This allows updating DOM elements in sync with the 3D scene without using Drei's Html component.

## Key Concepts

- `useFrame` works outside `<Canvas>` in R3F v10+
- Use refs to manipulate DOM elements directly for performance
- Throttle with `{ fps: N }` option since DOM manipulation is expensive
- Useful for HUDs, debug info, and UI that doesn't need to be in 3D space

## Usage

```tsx
const Ui = () => {
  const ref = useRef<HTMLDivElement>(null)

  useFrame(() => {
    ref.current.innerText = `${position.x.toFixed(2)}, ${position.y.toFixed(2)}`
  }, { fps: 10 })

  return <div ref={ref} className="fixed top-4 right-4" />
}

// Place outside Canvas
<Canvas>
  <Scene />
</Canvas>
<Ui />
```
