3-D Coming at You| 让你身历其境的 3-D 新视界

This dimension like no other makes the world pop out.

这种技术可是独一无二，让画面栩栩如生出现在你眼前。

Move over, 2-D; there's a new kid on the block—3-D. In fact, three-dimensional imagery has been around since the late 1890s. _(1)_

How is it that 3-D images appear as if they were flying out at you from the screen? _(2)_ The way humans see things is called binocular vision. Both your right and left eyes see the same object from slightly different angles, so each eye actually sees a different picture. The brain then merges them into a single, unified image while giving a sense of depth and distance. _(3)_ During a movie, two images are projected onto the same screen at the same time through different filters. Each side of the special 3-D glasses worn during the movie contains different filters as well. This means that the same scene is being viewed by both eyes, but from slightly different perspectives. _(4)_

This kind of technology is no longer limited to special movie theaters with viewers wearing uncomfortable glasses. _(5)_ The technology is already being applied to other electronic devices, such as mobile phones, personal computers, gaming systems, and televisions. There is no limit to what the future of three-dimensional technology may send your way, so don't blink!

(A) The answer is quite simple: your eyes are being fooled by your brain.

(B) New 3-D viewing systems that don't depend on glasses are being developed at the moment.

(C) Moviemakers take advantage of this to trick people into believing that they really perceive 3-D space.

(D) The human brain puts all this together, and everything on the screen blends into a seamless, moving, three-dimensional image.

(E) Thanks to recent blockbusters like Avatar, Alice in Wonderland, and How to Train Your Dragon, 3-D technology is now all the rage.

平面的 2-D 画面让一让，后起之秀的 3-D 来了。事实上，3-D 映像从 1890年代后期就已存在了。由于近来的卖座电影如《阿凡达》、《魔镜梦游》和《驯龙高手》的上映，3-D 技术现在可是蔚为风行。

3-D 影像是如何看起来像是从银幕里飞出来直逼你眼前呢？答案很简单，就是你的眼睛被大脑给蒙骗了。人类看东西的方式称为双眼视觉。你的右眼和左眼从些微不同的角度观看同样一个东西，因此左右眼实际上看到不同的影像。你的大脑接着将这些影像融合成单一的影像，同时给予深浅和远近的感官信息。电影制作者利用这个原理，让人们有错觉而相信他们真的感受到 3-D 空间。在电影中，透过不同滤光片，两个影像同时被投射到同一个银幕上，而观赏电影所配戴的特殊 3-D眼镜两边也各有不同的滤光镜片。这代表双眼会从些微不同的视角看到同一个画面。当人体大脑汇集这些画面，银幕上所有东西便融合成毫无间隙并且会移动的 3-D 影像。

这种科技已经不再局限于特殊的电影院、和需要观众配戴让人不舒服的眼镜才能达到效果。目前正在研发不用依赖眼镜的新 3-D 观赏系统。这种技术已经被应用到其他电子仪器，像是手机、个人计算机、游戏系统和电视等。未来的 3D技术发展无可限量，务必要张大眼睛拭目以待。

答案：  1. (E)2. (A)3. (C)4. (D)5. (B)

For Your Information

电影《阿凡达》的成功，除了宣告 3-D 技术到达一定的成熟度外，也带动一股 3-D 风潮，更多的 3-D电影即将要开拍或上映。导演詹姆斯‧柯麦隆（James Cameron）执导的《阿凡达》除了票房惊人外，还让 3-D 这项技术脱离过去仅是以儿童动画或恐怖惊悚、强调影像投射出的视觉刺激，过渡到以剧情为主、将观众引入『潘多拉』的世界。（参考数据：今周刊）
