Umusaruro wa Virtual ni iki?
Virtual production ni tekinike yo gukora firime ihuza amashusho nyayo yisi n'amashusho yakozwe na mudasobwa kugirango habeho ibidukikije bifotora mugihe nyacyo. Iterambere mubice bitunganya ibishushanyo (GPU) hamwe na tekinoroji ya moteri yimikino byatumye igihe nyacyo cyo gufotora (VFX) kibaho. Kugaragara kwa VFX kwifotoza-nyayo byateje impinduramatwara mubikorwa bya firime na tereviziyo. Hamwe nibikorwa biboneka, isi yumubiri na digitale irashobora gukorana neza hamwe nubwiza bwamafoto.
Mugushiramo tekinoroji yimikino yimikino kandi yibitseho rwoseLED mubikorwa byo guhanga ibikorwa, umusaruro wibikorwa byongera imikorere yuburyo bwo guhanga, biganisha kuburambe bwa ecran. Kurwego rwohejuru, umusaruro wibintu byemerera amakipe yo guhanga mbere yacecetse gufatanya mugihe nyacyo no gufata ibyemezo byihuse, kuko buri kipe ishobora kubona uko ishusho yanyuma izaba imeze mugihe cyo gufata amashusho nyirizina.
Ikoranabuhanga rihungabanya muri Filime na Televiziyo
Ikoranabuhanga rihungabanya bivuga udushya duhindura cyane uburyo abakoresha, inganda, nubucuruzi bakora. Ku nganda za firime na tereviziyo, ibi byatangiranye no kuva muri firime zicecetse zikajya mu biganiro, hanyuma ukava ku mwirabura-n-umweru ujya ibara, ugakurikirwa na tereviziyo, amashusho yo mu rugo, DVD, ndetse na vuba aha, serivisi zitambuka.
Mu myaka yashize, uburyo bwakoreshejwe mu gukora amafilime na televiziyo byahinduwe cyane mu ikoranabuhanga. Ihinduka rikomeye ryaganiriweho mugice gisigaye cyiyi ngingo ni uguhindura ingaruka zigezweho, byerekanwe na firime nkaParike ya JurassicnaTerminator. Izindi ntambwe zerekana filime VFX zirimoMatrix, Nyir'impeta, Avatar, naImbaraga rukuruzi. Abakunzi ba firime barashishikarizwa gusangira ibitekerezo byabo kuri firime zabaye abapayiniya cyangwa ibintu byingenzi muri VFX igezweho.
Ubusanzwe, gutunganya amafilime na TV byagabanijwemo ibyiciro bitatu: mbere yo gukora, gukora, na nyuma yumusaruro. Mubihe byashize, ingaruka ziboneka zashizweho mugihe cyinyuma yumusaruro, ariko uburyo bushya bwo gutanga umusaruro bwagiye bwimura byinshi mubikorwa bya VFX mubyiciro byabanjirije umusaruro no kubyara umusaruro, nyuma yumusaruro wabitswe kubirasa no gukosora nyuma yo kurasa.
LED Mugaragaza mubikorwa bihanga
Umusaruro wa Virtual uhuza tekinoroji nyinshi muri sisitemu imwe. Ubusanzwe imirima idafitanye isano irahuza, iganisha kubufatanye bushya, inzira, ikoranabuhanga, nibindi byinshi. Umusaruro wa Virtual uracyari muburyo bwo gutangira kwakirwa, kandi benshi barimo gukora kugirango babyumve.
Umuntu wese wakoze ubushakashatsi kuriyi ngingo ashobora kuba yarahuye ningingo za Mike Seymour kuri FX Guide,Ubuhanzi bwo Kubyaza umusaruro Virtual kurukuta rwa LED, Igice cya mberenaIgice cya kabiri. Izi ngingo zitanga ubushishozi mugukoraMandalorian, ikaba yararashwe cyane cyane kuri ecran ya LED.

Igice cya kabiri gisubiramo tekiniki nibibazo byahuye nabyo mugihe ushyira mubikorwa kamera VFX.
Kugabana uru rwego rwibitekerezo byubuyobozi bitera firime nabatunganya TV gusobanukirwa niterambere rigezweho ryikoranabuhanga. Hamwe na firime nyinshi hamwe na TV byerekana neza gukoresha igihe nyacyo VFX, irushanwa ryo kwemeza ibikorwa byanyuma ririmo. Kongera kwinjizwa mu musaruro w’ibanze byatewe ahanini n’icyorezo, cyatumye isi igana ku mirimo ya kure kandi isaba ubucuruzi n’imiryango yose kongera gutekereza ku buryo ikora.
Gushushanya LED ya ecran yo kubyara umusaruro
Urebye urwego rwikoranabuhanga rusabwa kugirango habeho umusaruro usanzwe, kumenya imikorere ya buri tekinoroji no gusobanukirwa nubusobanuro nyabwo bwibisobanuro bisaba ubufatanye hagati yinzobere mu nzego zitandukanye. Ibi biratuzanira intego nyayo yiyi ngingo, twandika duhereye ku nganda ziyobora inganda-ziyobora LED ku gukora ibishushanyo mbonera bya LED kugirango bibyare umusaruro.
LED Iboneza
Iboneza na curvature yubunini bwa LED ahanini bivana nuburyo background igaragara izafatwa nuburyo kamera izagenda mugihe cyo kurasa. Ijwi rizakoreshwa mugutangaza no gutambuka neza? Niba aribyo, kamera izarasa uhereye kumurongo uhamye cyangwa kuzenguruka ahantu hibandwa? Cyangwa ibiboneka bizakoreshwa kuri videwo yuzuye? Niba aribyo, ni gute abakozi nibikoresho bizafatwa mubunini? Ubu bwoko bwibitekerezo bufasha abashushanya LED kugena ingano yubunini bukwiye, niba ecran igomba kuba iringaniye cyangwa igoramye, hamwe nibisabwa ku mfuruka, ku gisenge, no / cyangwa hasi. Ibintu byingenzi byacungwa harimo gutanga canvas nini ihagije kugirango yemererwe kureba neza mugihe hagabanijwe guhinduranya ibara ryatewe no kureba impande za LED zigizwe na ecran.
Ikibanza cya Pixel
Imiterere ya Moiré irashobora kuba ikibazo gikomeye mugihegufata amashusho ya LED. Guhitamo pigiseli ikwiye nuburyo bwiza bwo gukuraho moiré. Niba utamenyereye pigiseli ya pigiseli, urashobora kwiga byinshi kubyerekeye hano. Imiterere ya Moiré iterwa nuburyo bwo kwivanga bwihuse buturuka kuri kamera ifata pigiseli imwe kuri ecran ya LED. Mubikorwa byukuri, isano iri hagati ya pigiseli ya pigiseli nintera yo kureba ntabwo ijyanye gusa na kamera ya kamera gusa ahubwo ijyanye nokugera hafi yibyerekezo byose. Ingaruka za Moiré zibaho mugihe intumbero iri murwego rwiza rwo kureba kuri pigiseli ihuye. Ubujyakuzimu-bwumurima burashobora kurushaho kugabanya ingaruka za moiré koroshya gato inyuma. Nukugirango igikumwe, gwiza pigiseli ikibanza icumi kugirango ubone intera nziza yo kureba mubirenge.
Kuvugurura igipimo na Flicker
Flicker mugihe amashusho yerekana amashusho cyangwa ecran ya LED biterwa no kudahuza hagati yikigereranyo cyo kugarura no kwerekana kamera. LED ya ecran isaba igipimo kinini cyo kugarura 3840Hz, ifasha gukuraho ecran ya flicker kandi irakenewe rwose mubikorwa bya progaramu isanzwe. Kugenzura niba ecran ya LED ifite igipimo cyinshi cyo kugarura ubuyanja nintambwe yambere yo kwirinda guhindagurika mugihe ufata amashusho, guhuza umuvuduko wa kamera na kamera yo kugarura niwo muti wanyuma wikibazo.
Umucyo
Kuri ecran ya LED ikoreshwa muri porogaramu zitari kamera, umucyo mwinshi ufatwa nkibyiza. Nyamara, kubikorwa byukuri, LED ya ecran akenshi irasa cyane, bityo urumuri rugabanuka cyane. Iyo urumuri rwa LED rugabanutse, imikorere yamabara igira ingaruka. Hamwe nimbaraga nkeya ziboneka kuri buri bara, ibara ryaragabanutse. Kugenzura niba urumuri rwinshi rwa LED ruhuza urumuri ntarengwa rusabwa kugirango urumuri ruhagije mububiko bwa LED rushobora kugabanya urugero urumuri rugomba kugabanuka no kugabanya gutakaza imikorere yibara.
Umwanya w'amabara, Icyatsi, na Itandukaniro
Imikorere yamabara ya ecran ya LED igizwe nibice bitatu byingenzi: umwanya wamabara, ibara ryinshi, nibitandukaniro. Umwanya wamabara na graycale bigira uruhare runini mubikorwa bya progaramu ya progaramu, mugihe itandukaniro ari rito.
Umwanya wamabara bivuga ishyirahamwe ryihariye ryamabara ecran ishobora kugeraho. Ababikora bagomba gusuzuma umwanya wamabara asabwa mbere, kuko ecran ya LED irashobora gushushanywa kugirango ibe ifite amabara atandukanye nibiba ngombwa.
Icyatsi, gipimye muri bits, cyerekana umubare wimbaraga ziboneka kuri buri bara. Mubisanzwe, hejuru yuburebure buke, niko amabara menshi aboneka, bikavamo guhinduranya amabara neza no gukuraho bande. Kubyakozwe muburyo bwa LED ecran, birasaba ibara rya bits 12 cyangwa irenga.
Itandukaniro ryerekeza ku itandukaniro riri hagati yera yera cyane n'umukara wijimye. Muri théorie, yemerera abareba gutandukanya ibiri mumashusho batitaye kumucyo. Ariko, ibi bisobanuro akenshi birasobanuka nabi. Umucyo mwinshi LED ecran ifite itandukaniro ryinshi. Ikindi gikabije ni ibintu byuzuza, ukoresheje LED nto (mubisanzwe bihendutse) LED irashobora kongera umukara mugaragaza, bityo igahindura itandukaniro. Nubwo itandukaniro ari ngombwa, ni ngombwa kumva ibintu byerekana itandukaniro.
Kwerekana amashusho
Gutegura neza ingano ya LED kumwanya no kubyaza umusaruro nintambwe yambere yo gushyira mubikorwa neza tekinoroji ya LED kubyara umusaruro. Urebye imiterere yihariye ya LED ya ecran, mubyukuri kubaka ingano ya LED mwisi ya 3D nuburyo bwiza cyane bwo gutegura ingano ya ecran, imirongo, kwishyiriraho, no kureba intera. Ibi bituma abaprofeseri naba injeniyeri bashobora kubona amajwi no kuganira kubikenewe hakiri kare, bagafata ibyemezo byuzuye mubikorwa.
Gutegura Urubuga
Icya nyuma ariko ntabwo ari gito, mugihe cyogushushanya, insanganyamatsiko zingenzi zurubuga, harimo ariko ntizigarukira kumiterere, imbaraga, amakuru, hamwe nibisabwa byo guhumeka, bifatwa nkibishushanyo mbonera kandi bikaganira ku bunini bwa LED. Izi ngingo zose zigomba gusuzumwa neza kandi zigatangwa kugirango harebwe ishyirwa mubikorwa rya ecran ya LED yagenewe.
Umwanzuro
Ibikorwa bya Virtual byerekana ihinduka rikomeye mubikorwa byo gukora amafilime, guhuza byimazeyo ibintu-byukuri hamwe nibidukikije bya digitale kugirango habeho amashusho atangaje, yifotora. Mugihe ikoranabuhanga rikomeje kugenda ryiyongera, uruhare rwa ecran ya LED yo mu rwego rwo hejuru iragenda iba ingenzi. Kubakora firime hamwe nitsinda ryababyara bashaka gukoresha imbaraga zumusaruro wukuri, guhitamo neza LED itanga ecran ni ngombwa.
Ibikoresho bya elegitoroniki bishyushye bihagaze ku isonga ryibi bishya, bitanga inganda-ziyobora-kureba-ecran ya LED yagenewe byumwihariko kubidukikije. Mugaragaza yacu yakozwe kugirango ihuze ibyifuzo bikomeye byo gukora firime zigezweho, bitanga amabara adasanzwe, ubwiza, hamwe no gukemura. Hamwe nuburambe bunini kandi twiyemeje kuba indashyikirwa, duhagaze neza kugirango dushyigikire umusaruro ukenewe kandi dufashe kuzana icyerekezo cyawe cyo guhanga mubuzima.
Kubindi bisobanuro byukuntuIbyuma bya elegitoronikiirashobora kuzamura umusaruro wawe wukuri, twandikire uyumunsi. Reka dufatanye gusunika imipaka yo gukora firime no gukora uburambe budasanzwe.
