我們這邊將改寫原本 本系列第10篇中使用的 <bounds/>

參考

https://github.com/pmndrs/drei#bounds

function Foo() {
  const bounds = useBounds()
  useEffect(() => {
    // Calculate scene bounds
    bounds.refresh().clip().fit()
    // Or, focus a specific object or box3
    // bounds.refresh(ref.current).clip().fit()
    // bounds.refresh(new THREE.Box3()).clip().fit()

<Bounds>
  <Foo />

建立另外兩個目標物後

圖很大你要忍一下
