This dimension like no other makes the world pop out.
這種技術可是獨一無二,讓畫面栩栩如生出現在你眼前。
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.
