Malangizo Ofulumira kwa Chidwi CG Kuwala

Njira Zosavuta Zowonjezera Kuwala mu Zithunzi Zanu za 3D ndi zojambula

Ndakhala ndikuyang'ana pazinthu zochuluka zomwe zikukhudza kuyatsa posachedwapa, ndipo ndakhala ndi mwayi wowonera kuyankhula kwa Gnomon Masterclass pa Efficient Cinematic Lighting ndi Jeremy Vickery (yemwe tsopano akugwira ntchito ngati katswiri wa zamalonda ku Pixar).

Ndakhala ndikutsatira luso la Jeremy kwa zaka zambiri. Ali ndi mafilimu okondweretsa kwambiri, ndipo anali mmodzi mwa ojambula oyamba omwe ndimatsatira pa DeviantArt (mwinamwake zaka zinayi kapena zisanu zapitazo).

Ndakhala ndikuyang'ana mozama kwambiri kubuku lachiwiri la James Gurney, Color and Light.

Ngakhale kuti amagwira ntchito m'mitundu yosiyanasiyana, James ndi Jeremy akuwoneka kuti ali ndi filosofi yofananako yowunika-kutanthauza kuti kuunika kukuyenera kuyandikira, koma kuti wojambulayo ayenera kudziwa komwe malamulo ndi malingaliro angasweke kapena kuwonjezereka kuti awonjezere kukula ndi chidwi.

Chikopa cha Jeremy ndi buku la Gurney onse amapereka uphungu wabwino kwambiri popanga kuunikira kwabwino.

Ndinayesa kuswa mfundo zina zazikulu kuti ndikugwiritseni ntchito ndi zithunzi za 3D.

Kumvetsetsa bwino 3 Kuunikira Pang'onopang'ono

Kuunikira katatu ndi njira yomwe imagwiritsidwa ntchito kwambiri pojambula zithunzi ndi kuwonetsera kanema, ndipo ndi chinthu chomwe mukufunikira kumvetsetsa kuti mupange zithunzi za CG zabwino.

Sindingalowe muzinthu zowonjezereka pano, koma kuunika kokhala ndi mfundo zitatu kumakhala kofanana ndi izi:

1. Kuunika Kofunika - Chitsime chachikulu chowunika, nthawi zambiri chimayikidwa madigiri 45 kutsogolo ndi pamwamba pa phunzirolo.
2. Kuwala Kuwala - Kuwala (kapena kukankha) kuwala ndi malo osungirako kuwala omwe akugwiritsidwa ntchito powunikira mthunzi. Kudzazidwa kumayikidwa mosiyana ndi fungulo.
3. Kuwala kwa Rim - Kuwala kwapadera ndi gwero lamphamvu, lowala bwino lomwe likuwalira pa phunziro kumbuyo, likulekanitsa phunziro kuchokera kumbuyo kwake popanga kuwala kochepa pambali pa silhouette.

Mafunde a Kuwala

Jeremy Vickery atangotchula njirayi pamasukulu ake, sindinaganizire kawiri kawiri, koma pamene ndinayamba kuyang'ana zojambula zowonjezereka zamagetsi ndikutsegula m'maganizo, zinandichitikira kuti ndikudziwika bwanji ndi, makamaka m'madera.

Ojambula zithunzi amatha kugwiritsa ntchito "mafunde a kuwala" pokhapokha atakakamiza kuwonjezera masewero ndi chidwi pa malo. Onani chithunzi chokongola ichi cha Victor Hugo, ndipo mvetserani momwe amagwiritsira ntchito dziwe lakuya la kuunikira kuti awonjezere masewera ku fanolo.

Ambiri opanga Sukulu ya Hudson River School amagwiritsa ntchito njira zomwezo.

Kuwala mu chilengedwe sikungokhala kosalekeza ndi yunifolomu, ndipo sikungowonongeka kuwonjezera. Mu phunziro la Jeremy, iye akuti cholinga chake ngati wojambula sikuti adzalengenso chenichenicho, ndiko kupanga chinthu chabwinoko. "Ndimagwirizana ndi mtima wonse.

Zochitika Zachilengedwe

Iyi ndi njira ina yomwe imathandiza kwambiri kwa akatswiri ojambula zithunzi omwe amafunika kumvetsa mozama zithunzi zawo.

Oyamba ayamba kulakwitsa kuti agwiritse ntchito kuunikira kosalekeza ndi mtundu wonse m'zochitika zawo zonse. Zoonadi, monga zinthu zimachokera kutali ndi kamera, ziyenera kutaya ndi kubwerera kumbuyo.

Zinthu zofunika kutsogolo ziyenera kukhala ndi zikhalidwe zamdima kwambiri. Pakatikatikati mwa nthaka ayenera kukhala ndi malo oyamba, kuunikiridwa molingana, ndi zinthu zomwe zili kumbuyo ziyenera kukhala zosinthika ndikusunthira kumbali ya mlengalenga. Kupitirira kutali chinthucho, chosazindikiritsa kwambiri chomwe chiyenera kukhala kuchokera kumbuyo kwake.

Pano pali kujambula kosangalatsa komwe kumatsindika mlengalenga (ndi kuunika kowala) kuti ukhale wozama.

Sewerani Mwachikondi Kuli Kozizira

Iyi ndi njira yamakono yopanga zojambula, pamene zinthu zikuunikira zimakhala ndi ubweya wofunda, pamene mthunzi amapezeka kawirikawiri.

Diss Rapoza, yemwe ndi fanizo lojambula zithunzi, amagwiritsira ntchito njirayi nthawi zambiri pazithunzi zake.

Gwiritsani Ntchito Kuunikira Kwambiri

Iyi ndi njira yomwe Gurney ndi Jeremy amagwira. Kuunikira kunayambika

Ndi njira yothandiza chifukwa imapereka owona kuti pali dziko lopitirira malire a chimango. Mthunzi wochokera ku mtengo wosawonekera kapena zenera sizowonjezerapo kodi mukuwonjezera mawonekedwe osangalatsa ku chithunzi chanu, kumathandizanso kukopa omvera anu ndikuwabatiza padziko lomwe mukuyesera kulenga.

Kugwiritsira ntchito gwero lowala lomwe likulepheretsedwera ndi omvera ndi njira yowonjezera yakulima malingaliro a chinsinsi kapena kudabwa. Njira imeneyi inagwiritsidwa ntchito mwakhama mu Pulp Fiction ndi Repo Man

Patulirani Pachiwiri

Kugawanika kwachiwiri kumakhala kofunika kwambiri pamene mukuyatsa zowunikira kapena zowonetsera. Aphatikizidwa momasuka, Vickery kwenikweni amapanga mawu otsatirawa mu phunziro lake la Gnomon:

"Mafilimu samafanana ndi luso lapamwamba, mwakuti anthu sangakhale ndi mwayi woima mu galamala ndikuwona chithunzi cha munthu aliyense kwa mphindi zisanu. Mafuti ambiri samatha kwa masekondi awiri, kotero onetsetsani kuti mumagwiritsa ntchito magetsi kuti mupange malo omwe amachoka pawindo. "

Apanso, zambiri za mawu amenewa zimagwiritsidwa ntchito m'mawu anga, koma mfundo yaikulu yomwe akuyesera kupanga ndi yakuti mu filimu ndi mafilimu mulibe nthawi yambiri kuti chithunzi chanu chikhale chowoneka.
