You can build such a thing yourself, using the pointer-events system implemented in react-three/xr v6. Take a look at how the To retrieve the transformation of the camera follow this tutorial. This all said, most AR / VR platforms (Meta Quest headsets) already automatically add a XRInputSource inside the viewers head position in case no controllers and hands are detected, which is already used by react-three/xr v6. |
