I changed the light direction and rotation of the ships.

我改变了光的方向和船的转动。

The primary way telescopes work is to change the direction light from an object is traveling.

望远镜的主要工作方式是改变物体发出的光的运动方向。

Mirrors also change the direction light travels, and if you used a curved mirror you can also bring light rays to a focus.

单面镜也可以改变光的传播方向，如果你使用曲面镜，你还可以让光线汇聚到一个焦点。
