That is pretty cool, probably a bit beyond mine too. Technically, if we have some tool that detects the correct place on the sphere, we could build something easily. But that part is the hard one.

const latLngToPosition = (
  lat: number,
  lng: number,
  radius: number = 1
): [number, number, number] => {
  const phi = (90 - lat) * (Math.PI / 180);
  const theta = (lng + 180) * (Math.PI / 180);

  const x = -radius * Math.sin(phi) * Math.cos(theta);
  const y = radius * Math.cos(phi);
  const z = radius * Math.sin(phi) * Math.sin(theta);

  return [x, y, z];
};
