react-three/flex

Placing content in THREE.js is hard. @react-three/flex brings the webs flexbox spec to react-three-fiber. It is based on Yoga, Facebook's open-source layout engine for react-native. Simply create layouts by wrapping your 3D objects in different <Box /> instances inside a <Flex /> container. This way they will be automatically placed in the 3D space following the flexbox specification just like in the DOM. You can tweak the container and the boxes using standard CSS flex properties, like flexDirection or justifyContent for the container and flexGrow for the boxes. There are also shorthands, like align and justify. When positioning items, react-three-flex needs to know where the object anchor is: Yoga Layout expects the object position to be relative to the upper left corner, which is the same as the DOM expects.
