+Calculates a boundary box and scales its children so the highest dimension is constrained by 1. NB: proportions are preserved.

+```tsx
+export type ResizeProps = JSX.IntrinsicElements['group'] & {
+  /** constrained by width dimension (x axis), undefined */

+  /** constrained by height dimension (y axis), undefined */
+  height?: boolean

+  precise?: boolean
+}
+```
+
+```jsx
+<Resize>
+  <mesh />
+</Resize>

+
+You can also specify the dimension to be constrained by:
+
+```jsx
+<Resize height>
+  <Box args={[70, 40, 20]}>
