create a react three fiber component that changes the camera location in javascript

To create a React Three Fiber component that changes the camera location, you can use the useThree hook provided by react-three-fiber. This hook gives you access to the three.js scene, camera, and gl objects, which you can manipulate to change the camera location.

Here's an example of how you can create a component that moves the camera around based on mouse movement:

import { Canvas, useFrame, useThree } from 'react-three-fiber'
import { PerspectiveCamera } from 'three'

const CameraControls = () => {
  const { camera } = useThree()

  useFrame(() => {
    // Update camera position based on mouse movement
    camera.position.x += (mouse.x - camera.position.x) * 0.05
    camera.position.y += (-mouse.y - camera.position.y) * 0.05
    camera.lookAt(0, 0, 0)
  })

  return null
}

const App = () => {
  return (
    <Canvas>
      <CameraControls />

      {/* Your 3D scene components go here */}
      {/* For example: <mesh geometry={...} material={...} position={[0, 0, 0]} /> */}
    </Canvas>
  )
}

export default App

In this example, we create a Canvas component from react-three-fiber and wrap our scene components inside it. We also create a CameraControls component that uses the useThree hook to access the camera object. Inside the useFrame hook, we update the camera's position based on mouse movement, and call lookAt to make it always look at the origin (0, 0, 0).

Remember to install the required dependencies (react-three-fiber and three) for this example to work.

Note: This is just a basic example, and you can customize the camera movement logic according to your specific requirements.
