Three js custom raycaster


export function z(x, y) {
  const origin = new THREE.Vector3(x - ref.cloud.offset[0], y - ref.cloud.offset[1], 0)
  const direction = new THREE.Vector3(0, 0, 1).normalize()
  const raycaster = new THREE.Raycaster(origin, direction)
  raycaster.params.Points.threshold = 0.1
  const intersects = raycaster.intersectObjects(ref.cloud.pointclouds, true)
  intersects.sort((a, b) => a.point.z - b.point.z)
  return intersects[0].point.z + ref.cloud.offset[2]
}

Three js raycaster WITHOUT camera

I seem to find only examples to use the raycaster with the camera, but none that just have a raycaster from Point A to Point B. I have a working raycaster, it retrieves my Helpers, Lines etc. but it seems it does not recognize my sphere.
