Iindlela ezilula zokuphucula ukuKhanya kwiiMifanekiso zakho ze-3D kunye neentlobo
Ndikhangela i-reference eninzi ejongene nokukhanyisa kutshanje, kwaye ndibe nethuba lokubukela inkulumo yeGnomon Masterclass kwi-Efficient Cinematic Lighting kunye noJeremy Vickery (okwangoku usebenza njengomlawuli wezobuchwepheshe kwiPixar).
Ndilandele ubugcisa bukaJeremy iminyaka. Unesimo esibucayi, isicatshulwa, kwaye wayengomnye wabaculi bokuqala endikulandele kwiDeviantArt (mhlawumbi emine okanye emihlanu edlulileyo).
Ndiye ndathatha ubunzulu bunzulu kwincwadi yesibini kaYames Gurney, uMbala kunye noKhanya.
Nangona basebenzisana nama-medium ahlukeneyo, uYakobi noJeremy babonakala babelana ngefilosofi efana noko malunga nokukhanya-okuthi, loo ndawo yokukhanya kufuneka ixoxwe ngokucatshulwa, kodwa ukuba umculi kufuneka wazi nokuba imigaqo kunye neengcamango zingaphula okanye zinyanyiswe ukuze zenzele kunye nomdla.
I-masterclass kaJeremy kunye nencwadi kaGurney bobabini banika iingcebiso ezintle zokudala ukukhanya ngokufanelekileyo kwindlela yokwakhiwa.
Ndizama ukuphula ezinye zeengongoma eziphambili ukuba zidlulisele kuwe ukuze zisebenzise ngemifanekiso ye-3D.

Qonda ukuPhumelela okuPhambili kwe-3
Ukukhanyiswa kwezinto ezintathu kusetyenziswe ngeteknoloji yokubonakalisa ukukhanya kunye ne-cinematic, kwaye yinto endiyifunayo ngokwenene ukudala imifanekiso emihle yeCG.
Andiyi kungena kwiinkcukacha ezininzi apha, kodwa ukucwangciswa kwezinto ezi-3 ezisisiseko ziza kufana nezi zilandelayo:
- UkuKhanya okuPhambili - Umthombo wokukhanya obalaseleyo, uhlala ubeka ama-degree angama-45 ngaphambili nangaphezulu kwesihloko.
- Gcwalisa Ukukhanya - Ukuzaliswa (okanye ukukhaba) ukukhanya okusemgangathweni umthombo wokukhanya wesibini osetyenziswayo ukukhanyisa indawo yezithunzi. Ukuzaliswa kufakwe ngokubhekiselele kwinqhosha.
- Ukukhanya kweRim - Ukukhanya kwesibhakabhaka kukukhanya okuqinileyo, okukhanyayo okukhanyayo kwisifundo esivela ngasemva, esetyenziselwa ukwahlula umxholo kwimvelaphi yakhe ngokudala isakhelo esincinci sokukhanya kunye nesicatshulwa somxholo.

Amachiza okuKhanya
Xa uJeremy Vickery eqala ukuthetha ngale ndlela kwi-masterclass yakhe, ndiphantse ndingacingi kabili malunga nalo, kodwa njengoko ndiqala ukukhangela ubuninzi bezithombe zobugcisa kunye nokukhanyisa engqondweni, kwenzeka kum ukuba yinto enobuninzi (kwaye isebenzayo) lo buchule , ngokukodwa kwimimandla.
I-digital artwork artists zisebenzisa "amachibi okukhanya" ecelwa ukuba acinge ukuba athenge umdlalo kunye nomdla kumdlalo. Khangela lo mzekeliso omhle nguVictor Hugo, kwaye uqaphele indlela asebenzisa ngayo igumbi eligxilile lokukhanyisa okukhazimulayo ukuongeza idrama kumfanekiso.
Abaninzi bee-Painting School zaseHurson basebenzisa iindlela ezifanayo.
Ukukhanya kwendalo akunqabile rhoqo kwaye kuyayifanana, kwaye akukho nto ibuhlungu ngayo. Kwintetho kaJeremy, uthi umgomo wakhe njengomculi awuyi kudala kwakhona into, ukwenza into engcono. "Ndiyavuma ngenhliziyo yonke.

Umoya ojongene nawo
Le yinye inqubo ebonakalayo iluncedo kubungcali bemvelo abafuna ukudala ubungqina bunzulu kwimifanekiso yabo.
Uninzi lwabaqalayo benza impazamo yokusebenzisa ukukhanya okuqhubekayo kunye nobunzima bombala kuwo wonke ummandla wabo. Enyanisweni, njengoko izinto zihamba kude nekhamera, zimele ziphele kwaye zenzeke ngaphakathi.
Izinto eziphambi kwexesha kufuneka zifumane ezinye zexabiso elimnyama kummandla. Umgangatho ophakathi kufuneka ube neendawo eziphambili, ukhanyiswe ngokufanelekileyo, kunye nezinto ezivela ngasemva kufuneka zichithwe kwaye zitshintshelwe kumbala wezulu. Ukugqithisa into leyo, into engachazwanga ngayo kufuneka ivela kwimvelaphi yayo.
Nanku umzobo oncomekayo ogxininisa imbono yomhlaba (kunye nokukhanya okuhlanganisiweyo) ukuphucula ubunzulu.

Dlala ngokufudumeleyo
Le ndlela yinkqubo yobuciko, apho izinto ezikhanyayo zihlala zifudumala, ngelixa iindawo zethunzi zidlalwa nge-blue cast.
Umbono wefantasy uMnuz Dave Rapoza usebenzisa le ndlela ngokuphindaphindiweyo kwimifanekiso yakhe.

Ukusetyenziswa okukhanyisiweyo
Le yinkqubo eyenziwa nguGurney noJeremy. Yenza ukukhanya
Isicwangciso esiluncedo kuba sinika umbukeli umbono wokuthi kukho ihlabathi ngaphaya kwemida yesakhelo. Isithunzi esivela kumthi ongabonakaliyo okanye iwindow engabangezeli nje kuphela ungezelela imilo enomdla kumfanekiso wakho, inceda ukunceda abaphulaphuli bakho kunye nokuzifaka kwihlabathi ozama ukuyidala.
Ukusebenzisa umthombo wokukhanya ophazamisayo ophazamiseka kumbono wabaphulaphuli uphuhliso lwesicatshulwa lokuhlakulela ingqiqo okanye ukubuza. Le ndlela yayisetyenziswe ngokugqithiseleyo kwi- Pulp Fiction kunye neRepo Man

Ukwahlula Okwesibini Ukwakhiwa
Ukwahlula okwesibini kubaluleke kakhulu xa ukhanyisa iifayile okanye iziboniso. Ephawulwe ngokukhululekile, iVickery yenza oko kulandelwayo kwintetho yakhe yeGnomon:
"Ifilimu ayifani nobugcisa obuhle, ngoxa abaphulaphuli abayi kuba nethuba lokuma kwigalari kwaye bajonga umfanekiso ngamnye ngomzuzu emihlanu. Amaphetshana amaninzi awapheli ngaphezu kwemizuzwana engama-2, ngoko qi ni sekisa ukuba usebenzisa ukukhanya kwakho ukudala indawo ephambili yokugxila kwesikrini ngokukhawuleza. "
Kwakhona, uninzi lwaloo catshulwa lichazwe ngamazwi am, kodwa ingongoma ephambili ezama ukuyenza kukuba kwifilimu kunye nefowuni awunayo ixesha elide lomfanekiso wakho ukwenza inkcazelo.
