迪士尼3D動畫同副眼鏡既原理

Linearly polarized glasses
To present a stereoscopic motion picture, two images are projected superimposed onto the same screen through orthogonal polarizing filters. It is best to use a silver screen so that polarization is preserved. The projectors can receive their outputs from a computer with a dual-head graphics card. The viewer wears low-cost eyeglasses which also contain a pair of orthogonal polarizing filters. As each filter only passes light which is similarly polarized and blocks the orthogonally polarized light, each eye only sees one of the images, and the effect is achieved. Linearly polarized glasses require the viewer to keep his head level, as tilting of the viewing filters will cause the images of the left and right channels to bleed over to the opposite channel – on the other hand, viewers learn very quickly not to tilt their heads. In addition, since no head tracking is involved, several people can view the stereocopic images at the same time.
There are several commercial systems offering products like the above, and one can also put one together by oneself using instructions on the GeoWall Consortium site – they refer to such a system as a GeoWall.

pokedigi1992君, 迪士尼個d 唔係紅藍鏡片既立體眼鏡, 係偏光鏡polarizor 來的.

如果用紅藍鏡片, 你唔會睇到顏色既卡通片, 只能是黑白. 迪士尼又點可能接受呢d質素既米奇老鼠, 唐老鴨卡通呢?

仲有, 係 lens, 唔係 lence.

ok, 咁啦, 在下去過本地既迪士尼, 係, 佢地係用偏光鏡, 唔係紅藍鏡片, 呢個在下可以證實.

只係作答時, 在下感覺用紅藍鏡片處理既卡通片, 算係落後既手法, 主要原因係冇色彩. 咁新既迪士尼樂園, 一定唔會想用舊科技, 一定唔會容許咁精彩, 又有香味又有噴水既節目, 畫面卻係黑白既. 黑白定係彩色, 就係在下想講既質素.

我們看到的不是黑白，而是「顏色既卡通片」，這是證明迪士尼並且用紅藍鏡片，因為用紅藍鏡片只能看見黑白。
但迪士尼不能接受這質素的米奇老鼠，並不能推論出由士尼用的不是紅藍鏡片，提出問題的提議在哪？

The animation is showed with two similar image
but with different colour
one is on the left & the other is on the right
they mix together so you can't detect it
When you wear the glasses
It should have one red lence &
one blue lence
the red lence only allow you to see one image
since it only allow red light pass through
the blue lence only allow blue light pass through
so your eyes see diffenert at the same time
and it make it seems to be 立體
