Chii chinonzi Virtual Production?
Kugadzirwa kweVirtual inzira yekugadzira mafirimu inosanganisa zviitiko zvepasirese nemifananidzo inogadzirwa nekombuta kuti igadzire mamiriro emifananidzo munguva chaiyo. Kufambira mberi mumifananidzo yekugadzirisa unit (GPU) uye tekinoroji yemitambo yakaita kuti real-time photorealistic visual effects (VFX) ive chokwadi. Kubuda kweiyo chaiyo-nguva photorealistic VFX kwakonzera shanduko muindasitiri yemafirimu neterevhizheni. Nekugadzirwa chaiko, nyika dzenyama nedzedhijitari zvino dzinogona kupindirana zvisina mutsetse nemhando yemifananidzo.
Nekubatanidza tekinoroji injini yemutambo uye kunyudza zvizereLED skrini mukugadzira kufambiswa kwebasa, kugadzirwa chaiko kunowedzera kugona kwemaitiro ekugadzira, zvichitungamira kune imwe isina musono skrini chiitiko. Padanho repamusoro, kugadzirwa chaiko kunobvumira zvikwata zvekugadzira zvakambomira kuti zvibatane munguva chaiyo uye kuita sarudzo nekukurumidza, sezvo timu yega yega ichigona kuona kuti pfuti yekupedzisira ichataridzika sei panguva yekudhirowa chaiko.
Inovhiringidza Tekinoroji muFirimu neTerevhizheni
Kuvhiringidza tekinoroji inoreva hunyanzvi hunochinja zvakanyanya mashandiro anoita vatengi, maindasitiri, uye mabhizinesi. Kune indasitiri yemafirimu neterevhizheni, izvi zvakatanga nekuchinja kubva kumafirimu akanyarara kuenda kune talkies, zvino kubva mutema-ne-chena kuenda kune ruvara, zvichiteverwa neterevhizheni, matepi emavhidhiyo epamba, maDVD, uye nguva pfupi yapfuura, masevhisi ekutepfenyura.
Kwemakore, nzira dzinoshandiswa kugadzira mafirimu nemitambo yeTV dzakave neshanduko huru yetekinoroji. Shanduko huru yakurukurwa mune yasara yechinyorwa chino ishanduko kune yemazuva ano maitiro ekuona, akapinzwa nemafirimu akaita se.Jurassic ParkuyeThe Terminator. Mamwe akakosha VFX mafirimu anosanganisiraThe Matrix, Ishe Wezvindori, Avatar,uyeSimba regiravhiti. Vanofarira mafirimu vanokurudzirwa kugovera pfungwa dzavo pamusoro pemafirimu aive mapiyona kana zviitiko zvakakosha muVFX yemazuva ano.
Nechinyakare, kugadzirwa kwemafirimu neTV kwakakamurwa kuita matanho matatu: pre-kugadzirwa, kugadzira, uye post-kugadzirwa. Munguva yakapfuura, maitiro ekuona akagadzirwa panguva yekugadzirwa kwemashure, asi nzira dzekugadzira dziri kusimukira dzakafambisa yakawanda yeVFX maitiro mune pre-yekugadzira uye nhanho dzekugadzira, ine post-kugadzirwa yakachengeterwa chaiwo mapfuti uye post-pfuti inogadzirisa.
LED Screens muCreative Workflows
Kugadzirwa kweVirtual kunobatanidza akawanda matekinoroji kuita imwechete, yakabatana system. Nechinyakare minda isina hukama iri kutenderera, zvichitungamira kune hutsva hwekudyidzana, maitiro, matekinoroji, nezvimwe. Kugadzirwa kweVirtual kuchiri mudanho rekutanga rekugamuchira, uye vazhinji vari kushanda kuti vazvinzwisise.
Chero ani akatsvaga iyi musoro anogona kunge akawana zvinyorwa zvaMike Seymour paFX Guide,Iyo Art yeVirtual Production pamadziro eLED, Chikamu ChekutangauyeChikamu Chechipiri. Zvinyorwa izvi zvinopa ruzivo rwekuitaThe Mandalorian, iyo yakanyanya kupfurwa pa-direct-view LED skrini. Seymour anotsanangura zvidzidzo zvakadzidzwa panguva yekugadzirwa kweThe Mandalorianuye kuti dhizaini yekugadzira iri kushandura sei kugadzira workflows. Chikamu chechipiri chinoongorora hunyanzvi hwekuita uye matambudziko anotarisana nawo pakuita mu-kamera VFX.
Kugovera iyi nhanho yehutungamiriri hwepfungwa inotyaira mafirimu uye vagadziri veTV kunzwisisa kweazvino tekinoroji kufambira mberi. Nemafirimu akati wandei uye TV inoratidza zvinobudirira kushandisa chaiyo-nguva VFX, mujaho wekutora ichangoburwa workflows iripo. Kumwe kutorwa kwekugadzirwa chaiko kwave kufambiswa nedenda, iro rakasundira nyika kubasa riri kure uye zvaida kuti mabhizinesi ese nemasangano afunge zvakare mashandiro avanoita.
Kugadzira LED Screens yeVirtual Production
Tichifunga nezve huwandu hwetekinoroji inodiwa pakugadzirwa chaiko, kuona mashandiro etekinoroji uye kunzwisisa zvazvinoreva chaizvo zvinoda kudyidzana pakati penyanzvi dzinobva kwakasiyana siyana. Izvi zvinotisvitsa kuchinangwa chechokwadi chechinyorwa ichi, kunyora kubva pakuona kweindasitiri-inotungamira yakananga-kutarisa LED mugadziri pakugadzira ma LED skrini ekugadzira chaiwo.
