code: function rayPlaneIntersection(planeNormal, planeConstant, rayDirection) {
    // A line from the camera position toward (and through) the plane
    const distanceToPlane = planeConstant / planeNormal.dot(rayDirection);
    return rayDirection.multiplyScalar(distanceToPlane);
  }
docs: @param planeNormal {THREE.Vector3}
  @param planeConstant {Float} Distance from origin of the plane
  @param rayDirection {THREE.Vector3} Direction of ray from the origin
  
  @return {THREE.Vector3} The intersection point of the ray and plane
