Do you know 3D movies?When you see one,it's like the story is happening in front of you,and you are part of it.3D movies are exciting to watch,but do you know how to make them,and why you need to wear a pair of 3D glasses?To understand these questions,let's do an easy experiment.
  Put a finger in front of your eyes.
  Cover your left eye and look at the finger.
  Cover your right eye and look at the finger.
  What do you see?The finger you see with your left eye is in a different position from the one you see with your right eye.This means you get two images(图像)when you look at something with both your eyes.To make a 3D movie,people have to get two images at the same time,so they use two video cameras.When playing a 3D movie,they use two projectors (放映机) at the same time.This brings two images together on the screen.Then,we use 3D glasses to separate (分离)the two images.One image enters one eye and the other image enters the other eye.
  Then our brains put the two images together.This way,we get 3D pictures
你知道3D电影吗?当你看3D电影时,里面的故事就像在你的眼前发生一样,而你也是故事里的一部分.看3D 电影令人激动,但是你知道怎样制作3D电影吗?为什么要带上3D眼睛呢?为了了解这些问题,让我们做一个简单的实验.
把你的一个手指放在你的眼前.
蒙住你的左眼看你的那个手指.
接下来蒙住你的右眼再看你的手指.
你看到了什么?用你的左眼看到手指的位置与用右眼看到的手指位置不一样.这就是说当你用2只眼睛看物体时你看到了2个图像.要制造出3D电影,人们就必须在同一时间里看到2个物像,因此他们要用2个摄影机.当人们在看3D电影时,他们也要同时使用2个放映机.这样就会在屏幕上2个物像就重合到了一起.之后,当我们用3D眼睛去把这2个物像分开.一个图像进入一只眼睛,另一个图像进入另一只眼睛.
然后,我们的大脑把这2个图像组合到一起.用这种方法,我们就得到了3D图片.
