Iiglasi ze-3D, ezikwabizwa ngokuba "ziiglasi ze-stereoscopic," ziiglasi ezikhethekileyo ezinokusetyenziswa ukujonga imifanekiso ye-3D okanye imifanekiso.Iiglasi ze-Stereoscopic zohlulwe kwiindidi ezininzi zemibala, eqhelekileyo ibomvu eluhlaza okwesibhakabhaka kunye neblue blue.
Umbono kukuvumela omabini amehlo ukuba abone umfanekiso omnye kwimibini yomfanekiso we-3D, usebenzisa ukudlula kokukhanya ngokuhambelanayo kunye nemibala eyahlukeneyo.Iifilimu ze-3D ziya zithandwa ngakumbi phakathi kwabaphulaphuli.Okwangoku, kukho iintlobo ezintathu zeeglasi ze-3D kwimarike: i-chromatic aberration, i-polarizing kunye neqhezu lexesha.Umgaqo-siseko kukuba amehlo amabini afumana imifanekiso eyahlukeneyo, kwaye ingqondo iya kudibanisa idatha evela kumacala omabini ukudala umphumo we-dimensional.
Ifiziksi yeeglasi ze3D
Amaza okukhanya yi-electromagnetic wave, i-electromagnetic wave liza le-shear, icala le-shear wave vibration kunye nesalathiso sosasazo sikwi-perpendicular.Ukukhanya kwendalo okusasazeka kwicala elithile, isalathiso saso sokungcangcazela sifumaneka kuwo onke amacala kwinqwelomoya ejonge kwicala losasazo.Ukuba, xa ukungcangcazela okunecala elinye kuphela kubizwa ngokuba yi-linear polarized ngalo mzuzu, indlela ifilim ecandekileyo ecacileyo yeyona ndlela ifanelekileyo, embindini wefilimu yelensi ephothiweyo iqulethe iikristale ezininzi zeentonga ezincinci, zicwangciswe ngokulungeleleneyo kwicala elinye, ukuze ukwazi ukubeka ukukhanya kwendalo ukuze kuguqulwe emehlweni ethu.Njenge:
Umgaqo we-polarized 3D glasses kukuba iliso lasekhohlo kunye neso lasekunene leeglasi zixhotyiswe ngokulandelelana kunye ne-polarizer enqamlezayo kunye ne-longitudinal polarizer.Ngale ndlela, xa ifilimu eyenziwe kusetyenziswa itekhnoloji yokukhanya kwepolarized idlalwa, umfanekiso welensi ekhohlo uhluzwa ngepolarizer enqamlezayo ukuze ufumane ukukhanya okunqamlezileyo, kwaye umfanekiso welensi yasekunene ihluzwa ngepolarizer yobude ukufumana ukukhanya okude.
Ukusebenzisa le propati yokukhanya kwepolarized yeyona nto ifunwa yi-cinema ye-stereoscopic -- ukwenza amehlo asekunene nasekhohlo abonakale ahluke ngokupheleleyo.Ngokuxhobisa iiprojektha ezimbini ngeepolarizers, iprojekti iprojektha ngokugqibeleleyo amaza okukhanya alungelelaniswe ngokuthe ngqo komnye nomnye, kwaye emva koko umbukeli unokubona amehlo asekunene nasekhohlo omnye komnye ngaphandle kokuphazamiseka ngeendondo ezithile zepolarized.
Ngaphambili, iiglasi ze-3D ze-polarized zazatyiswa nje nge-polarizing layer phezu kweeglasi eziqhelekileyo ukwenza ifilimu ye-polarizing, eyayingabizi kakhulu.Kodwa le ndlela inesiphako, ngelixa ibukele ifilimu ukuba ihlale ngokuthe tye, ayikwazi ukuthobisa intloko, ngaphandle koko iya kuba kabini.Ngoku, xa ubukele i-movie ye-3D, iilensi ze-polarizing ezinxitywa ngabaphulaphuli zi-polarizers ezijikelezayo, oko kukuthi, enye ishiywe i-polarized kwaye enye ilungile i-polarized, enokuthi ivumele amehlo abaphulaphuli asekhohlo nasekunene abone imifanekiso eyahlukeneyo, kwaye kungakhathaliseki ukuba ijika njani intloko, akuyi kubakho mbono kabini.
Cacisa ukuhlelwa
Imowudi yomahluko wombala yeyona ndlela iphantsi yokubukela iimuvi.Isixhobo sokudlala siya kubonisa imifanekiso yasekhohlo nasekunene ngemibala eyahlukeneyo (obomvu nobhlowu ziqhelekile).Ngeeglasi, iliso lasekhohlo linokubona kuphela umfanekiso we-A (njengokukhanya okubomvu) kwaye iliso lasekunene linokubona kuphela umfanekiso we-B umbala (njengokukhanya okuluhlaza okwesibhakabhaka), ukuze kuqatshelwe umboniso we-dimensional emithathu yomfanekiso wamehlo asekhohlo nasekunene.Kodwa xa umbala usondele kwisihluzi esibomvu ungagqitywanga okanye i-blue filter ayigqitywanga, kuya kubakho ithunzi eliphindwe kabini, kunzima ukuba nefuthe eligqibeleleyo.Ixesha elide emva kokuba amehlo aphinde abangele ixesha elifutshane lokucalulwa kombala obangelwa ngumqobo.
Imowudi yokuvala iphunyezwa ngokutshintsha phakathi kwezakhelo zamehlo zasekhohlo nasekunene ukufezekisa umphumo we-3D.Ngokungafaniyo ne-polarizing, imowudi yokuvala itekhnoloji esebenzayo ye-3D.Umdlali we-3D ovalayo uya kutshintsha ngokusebenzayo phakathi kweliso lasekhohlo kunye neliso lasekunene.Oko kukuthi, kwangaxeshanye, umfanekiso we-3D wepolarized uqulethe yomibini imifanekiso esekhohlo nasekunene ngaxeshanye, kodwa uhlobo lwesivalo luyimifanekiso esekhohlo okanye ekunene kuphela, kwaye iindondo ze-3D zitshintsha amehlo asekhohlo nasekunene ngaxeshanye.Xa isikrini sibonisa iliso lasekhohlo, iiglasi zivula iliso lasekhohlo kwaye zivale iliso lasekunene;Xa isikrini sibonisa iliso lasekunene, iindondo zivula iliso lasekunene kwaye zivale iliso lasekhohlo.Ngenxa yokuba isantya sokutshintsha sifutshane kakhulu kunexesha lexeshana lombono womntu, akunakwenzeka ukuva i-flicker yomfanekiso xa ubukele ifilimu.Kodwa itekhnoloji igcina isisombululo sokuqala somfanekiso, okwenza kube lula kubasebenzisi ukonwabela i-HD 3D epheleleyo ngaphandle kokuthoba ukuqaqamba komfanekiso.
