ʻO nā aniani 3D, ʻike ʻia hoʻi ʻo "nā aniani stereoscopic," he mau aniani kūikawā hiki ke hoʻohana ʻia e nānā i nā kiʻi 3D a i ʻole nā kiʻi.Hoʻokaʻawale ʻia nā aniani stereoscopic i nā ʻano kala he nui, ʻoi aku ka maʻamau o ka ʻulaʻula uliuli a me ka ʻulaʻula uliuli.
ʻO ka manaʻo e ʻae i nā maka ʻelua e ʻike i hoʻokahi wale nō o nā kiʻi ʻelua o ke kiʻi 3D, me ka hoʻohana ʻana i ke ala o ka mālamalama i nā kala like ʻole.Ke ulu nui nei nā kiʻiʻoniʻoni 3D i waena o ka poʻe hoʻolohe.I kēia manawa, ʻekolu ʻano o nā aniani 3D ma ka mākeke: chromatic aberration, polarizing a me ka hapa manawa.ʻO ke kumukānāwai e loaʻa i nā maka ʻelua nā kiʻi like ʻole, a e hui pū ka lolo i ka ʻikepili mai nā ʻaoʻao ʻelua e hana i kahi hopena ʻekolu.
ʻO ka physics o nā aniani 3D
ʻO ka nalu māmā he hawewe electromagnetic, ʻo ka hawewe electromagnetic ka nalu shear, ʻo ke kuhikuhi hawewe ʻauʻau a me ke kuhikuhi hoʻolaha ʻana he perpendicular.No ka malamalama maoli e hoolaha ana ma kekahi aoao, aia kona kuhikuhi haalulu ma na aoao a pau o ka mokulele e ku pono ana i ka aoao hoolaha.Inā, ke kapa ʻia ka haʻalulu me hoʻokahi ʻaoʻao i ka linear polarized i kēia manawa, ʻo ke ala o ka nui o ka linear polarized, polarizing film ke ala maʻalahi loa, aia ma waena o ka kiʻi ʻoniʻoni polarized he nui nā koʻokoʻo crystals liʻiliʻi, ua hoʻonohonoho pono ʻia i ka ʻaoʻao hoʻokahi, i hiki iā ʻoe ke kau i ka mālamalama maoli e lilo i polarized i loko o ko mākou mau maka.E like me:
ʻO ke kumu o nā aniani 3D polarized ʻo ia ka maka hema a me ka maka ʻākau o nā aniani i hoʻolako ʻia me kahi polarizer transverse a me ka polarizer longitudinal.Ma kēiaʻano, ke hoʻokaniʻia ke kiʻi i hanaʻia me kaʻenehana māmā polarized, ua kānana ke kiʻi o ka lens hema ma o ka polarizer transverse e loaʻa ai ke kukui polarized transverse, a ua kānanaʻia ke kiʻi o ka lens akau ma o ka polarizer longitudinal e loaʻa ai ke kukui polarized longitudinal.
ʻO ka hoʻohana ʻana i kēia waiwai o ke kukui polarized ʻo ia ka mea e pono ai ka hale kiʻiʻoniʻoni stereoscopic -- i mea e ʻokoʻa loa ai nā maka ʻākau a me nā maka hema.Ma ka hoʻolako ʻana i ʻelua projectors me nā polarizer, hana nā projectors i nā nalu māmā polarized e kū pono ana kekahi i kekahi, a laila hiki i ka mea nānā ke ʻike i nā maka ʻākau a hema o kekahi me ke keakea ʻole ma o nā aniani polarized kikoʻī.
I ka wā ma mua, ua uhi wale ʻia nā makaaniani polarized 3D me kahi papa polarizing ma luna o ka ʻili o nā aniani maʻamau e hana i ke kiʻi polarizing, he mea maʻalahi loa.Akā, he hemahema kēia ʻano, ʻoiai e nānā ana i ke kiʻiʻoniʻoni e noho pololei, ʻaʻole hiki ke hoʻohuli i ke poʻo, i ʻole e pālua.I kēia manawa, i ka nānā ʻana i kahi kiʻiʻoniʻoni 3D, ʻo nā lens polarizing i ʻaʻahu ʻia e ka poʻe he poʻe poʻokela, ʻo ia hoʻi, waiho ʻia kekahi polarized a ʻo kekahi polarized ʻākau, hiki ke ʻike i nā kiʻi ʻokoʻa i nā maka hema a me ka ʻākau, a ʻaʻohe mea e hoʻohuli i ke poʻo, ʻaʻohe ʻike pālua.
Hoʻokaʻawale kikoʻī
ʻO ke ʻano ʻokoʻa kala ke ala haʻahaʻa loa e nānā i nā kiʻiʻoniʻoni.E hōʻike ka mea pāʻani i nā kiʻi hema a me nā kiʻi ʻākau i nā kala like ʻole (ʻulaʻula a me ka uliuli ka mea maʻamau).Me nā aniani, hiki i ka maka hema ke ʻike wale i ke kiʻi o A waihoʻoluʻu (e like me ke kukui ʻulaʻula) a ʻo ka maka ʻākau ke ʻike wale i ke kiʻi o ka waihoʻoluʻu B (e like me ke kukui polū), i ʻike ai i ka hōʻike ʻekolu-dimensional o ke kiʻi o ka maka hema a me ka ʻākau.Akā i ka wā e kokoke ana ke kala i ka kānana ʻulaʻula ʻaʻole i hoʻopau ʻia a ʻaʻole i pau ka kānana polū, e loaʻa ka malu pālua, paʻakikī ka loaʻa ʻana o kahi hopena kūpono.ʻO ka lōʻihi ma hope o nā maka e hoʻoulu ai i kahi manawa pōkole o ka hoʻokae kala i hana ʻia e ka keakea.
Loaʻa ke ʻano pani pani ma ka hoʻololi ʻana ma waena o nā kiʻi maka hema a me ka ʻākau e loaʻa ai kahi hopena 3D.ʻAʻole like me ka polarizing, ʻo ka mode shutter kahi ʻenehana 3D ikaika.E hoʻololi ikaika ka mea pāʻani 3D pani ma waena o ka maka hema a me ka maka ʻākau.ʻO ia hoʻi, i ka manawa like, aia nā kiʻi 3D polarized i nā kiʻi hema a me nā kiʻi ʻākau i ka manawa like, akā ʻo ke ʻano pani he mau kiʻi hema a ʻākau wale nō, a hoʻololi nā aniani 3D i nā maka hema a me ka ʻākau i ka manawa like.Ke hōʻike ka pale i ka maka hema, wehe nā aniani i ka maka hema a pani i ka maka ʻākau;Ke hōʻike ka pale i ka maka ʻākau, wehe nā aniani i ka maka ʻākau a pani i ka maka hema.No ka mea ʻoi aku ka pōkole o ka wikiwiki o ka hoʻololi ʻana ma mua o ka manawa pōkole o ka ʻike kanaka, ʻaʻole hiki ke ʻike i ka ʻōlinolino o ke kiʻi i ka wā e nānā ana i ke kiʻiʻoniʻoni.Akā, mālama ka ʻenehana i ka hoʻonā kumu mua o ke kiʻi, e maʻalahi i nā mea hoʻohana ke hauʻoli i ka piha HD piha 3D me ka hoʻohaʻahaʻa ʻole i ka ʻōlinolino o ke kiʻi.
