Izibuko ze-3D, ezaziwa nangokuthi "izibuko ze-stereoscopic," ziyizibuko ezikhethekile ezingasetshenziswa ukubuka izithombe ze-3D noma izithombe.Izingilazi ze-stereoscopic zihlukaniswe ngezinhlobo eziningi zemibala, ezivame kakhulu ezibomvu eziluhlaza okwesibhakabhaka nokubomvu okwesibhakabhaka.
Umqondo uwukuvumela womabili amehlo ukuthi abone isithombe esisodwa kwezimbili zesithombe se-3D, kusetshenziswa ukudlula kokukhanya ngemibala ehambisanayo nehlukile.Amafilimu e-3D aya ngokuya ethandwa kakhulu phakathi kwababukeli.Njengamanje, kunezinhlobo ezintathu zezibuko ze-3D emakethe: i-chromatic aberration, polarizing kanye nengxenye yesikhathi.Isimiso siwukuthi amehlo amabili athola izithombe ezihlukene, futhi ubuchopho buzohlanganisa idatha evela ezinhlangothini zombili ukuze kwakhe umphumela we-three-dimensional.
I-physics yezibuko ze-3D
Igagasi lokukhanya igagasi logesi, igagasi logesi liyi-shear wave, isiqondiso sokudlidliza kwe-shear wave futhi isiqondiso sokusakazeka sibheke eceleni.Ngokukhanya kwemvelo okusakazekela ohlangothini oluthile, isiqondiso sakho sokudlidliza sitholakala kuzo zonke izinhlangothi endizeni eqondana nesiqondiso sokusakazeka.Uma, lapho ukudlidliza okunesiqondiso esisodwa kuphela kubizwa ngokuthi i-linear polarized ngalesi sikhathi, indlela ifilimu yomugqa ehlukanisiwe, ehlukanisayo iyindlela elula kakhulu, phakathi kwefilimu yelensi ehlukanisiwe iqukethe amakristalu amancanyana amaningi, ahlelwa ngokulinganayo ngendlela eyodwa, ukuze ukwazi ukubeka ukukhanya kwemvelo ukuze kubonakale emehlweni ethu.Njenge:
Umgomo wezingilazi ze-3D ezenziwe nge-polarized ukuthi iso lesokunxele neso langakwesokudla lezibuko zihlonyiswe ngokulandelanayo nge-polarizer eguquguqukayo kanye ne-polarizer ye-longitudinal.Ngale ndlela, lapho ifilimu eyenziwe kusetshenziswa ubuchwepheshe bokukhanya obuhlukanisiwe idlalwa, isithombe selensi yesokunxele sihlungwa nge-polarizer enqamulayo ukuze kutholwe ukukhanya kwe-polarized transverse, futhi isithombe selensi yesokudla sihlungwa nge-polarizer ye-longitudinal ukuze kutholwe ukukhanya kwe-polarized longitudinal.
Ukusebenzisa lesi sici sokukhanya kwe-polarized yikho kanye okudingwa yi-cinema ye-stereoscopic -- ukwenza amehlo angakwesokudla nakwesokunxele abukeke ehluke ngokuphelele.Ngokuhlomisa amaphrojektha amabili ngama-polarizer, amaphrojektha akhiqiza amaza okukhanya ahlukaniswe kahle aqondana namanye, bese umbukeli ekwazi ukubonana ngamehlo angakwesokudla nakwesokunxele ngaphandle kokuphazamiseka ngezingilazi ezithile ze-polarized.
Esikhathini esedlule, izingilazi ze-3D ezine-polarized zazivele zimbozwe ngesendlalelo se-polarizing ebusweni bezingilazi ezijwayelekile ukuze zenze ifilimu e-polarizing, eyayishibhile kakhulu.Kodwa le ndlela inesici, ngenkathi ubuka ifilimu ukuze uhlale uqondile, awukwazi ukutshekisa ikhanda, ngaphandle kwalokho kuyoba kabili.Manje, lapho ubuka ifilimu ye-3D, amalensi ahlukanisayo agqokwa izethameli ayizimbotshana eziyindilinga, okungukuthi, enye ishiywe i-polarized kanti enye i-polarized kwesokudla, engavumela futhi amehlo ezithameli kwesokunxele nakwesokudla ukuthi abone izithombe ezahlukene, futhi kungakhathaliseki ukuthi ikhanda litshekiswa kanjani, ngeke kube nombono okabili.
Ukuhlukanisa ngezigaba
Imodi yomehluko wombala iyindlela eshibhe kakhulu yokubuka amamuvi.Idivayisi yokudlala izoveza izithombe ezingakwesokunxele nezingakwesokudla ngemibala ehlukene (okubomvu nokuluhlaza okwesibhakabhaka kuvamile).Ngezibuko, iso lesokunxele lingabona kuphela isithombe sombala A (njengokukhanya okubomvu) futhi iso lesokudla lingabona kuphela isithombe sombala B (njengokukhanya okuluhlaza okwesibhakabhaka), ukuze libone isethulo sezinhlangothi ezintathu sesithombe samehlo angakwesokunxele nangakwesokudla.Kodwa uma umbala useduze nesihlungi esibomvu ungaqediwe noma isihlungi esiluhlaza okwesibhakabhaka singaqediwe, kuzoba nethunzi eliphindwe kabili, kunzima ukuba nomthelela ophelele.Isikhathi eside emva kwamehlo kuzophinde kubangele isikhathi esifushane sokucwaswa kombala okubangelwa isithiyo.
Imodi ye-shutter ifinyelelwa ngokushintsha phakathi kwezinhlaka zamehlo kwesokunxele nakwesokudla ukuze kuzuzwe umphumela we-3D.Ngokungafani ne-polarizing, imodi yokuvala iwubuchwepheshe obusebenzayo be-3D.Isidlali se-3D se-shutter sizoshintsha phakathi kweso lesokunxele neso lesokudla.Okusho ukuthi, ngesikhathi esifanayo, isithombe se-3D esihlukanisiwe siqukethe kokubili izithombe kwesokunxele nesokudla ngesikhathi esisodwa, kodwa uhlobo lwe-shutter luyizithombe ezingakwesokunxele noma ezingakwesokudla kuphela, futhi izibuko ze-3D zishintsha amehlo kwesokunxele nakwesokudla ngesikhathi esisodwa.Uma isikrini sibonisa iso lesokunxele, izibuko zivula iso lesokunxele bese zivala iso lesokudla;Uma isikrini sibonisa iso langakwesokudla, izibuko zivula iso langakwesokudla bese zivala iso lesokunxele.Ngenxa yokuthi ijubane lokushintsha lifushane kakhulu kunesikhathi sombono womuntu wesikhashana, akunakwenzeka ukuzwa ukucwayiza kwesithombe lapho ubuka ifilimu.Kodwa ubuchwepheshe bugcina ukulungiswa kwangempela kwesithombe, okwenza kube lula kubasebenzisi ukujabulela i-HD 3D yangempela yangempela ngaphandle kokululaza ukukhanya kwesithombe.
