Using objectSpecificData to get additional information about the tracked object.

//@input Component.ObjectTracking3D objectTracking3D

script.createEvent("UpdateEvent").bind(()=> {

    // In Lens Studio we do not have the objectSpecificData we need.
    if (global.deviceInfoSystem.isEditor()) {
      return new vec3(0, 1, -35);
