The function lookAt() in the Object3D in revision 88 and above of three.js has been changed, so there caught a problem that mesh can't be seen.
then I modified: "centerHigh = new THREE.Vector3(centerHigh.x, centerHigh.y, centerHigh.z)" at line 205 in CesiumThree.js .and it works.
After all, Cartesian3 can't be used as Vector3 at all situations.
