Njira Zosavuta Zomwe Zidzakupangitse Kuti Zinthu Zanu Zidzakupindulitseni Zambiri
Kujambula zithunzi ndi chimodzi mwa zolinga zabwino kwa akatswiri ambiri a CG, ndipo ndi chimodzi mwa zovuta kwambiri kuzikwaniritsa. Ngakhale mutakhala atsopano ku 3D makanema makanema , komabe zida zamakono ndi njira zopangira ntchito zimapangitsa kuti chithunzichi chipezeke. Nazi njira zisanu ndi zitatu zothandizira kuti ufike kumeneko:

Bevel, Bevel, Bevel
Kuiwala kuti kulira kapena kumaphatikiza m'mphepete ndi chimodzi mwa zolakwa zambiri zomwe zimachitika ndi ojambula ojambula 3D. Paliponse paliponse paliponse m'mlengalenga, ndipo ngakhale zinthu zambiri zopangidwa ndi anthu zimakhala zozungulira pang'ono pomwe malo awiri otsutsana amakumana. Kuwombera kumathandizira kufotokozera mwatsatanetsatane, ndipo kumagulitsa kwenikweni zenizeni za chitsanzo chanu mwa kulola m'mphepete kuti mugwire bwino mfundo zazikulu kuchokera pazowunikira kwanu.
Kugwiritsira ntchito bevel (kapena chamfer tool mu 3ds Max) ndi chimodzi mwa zinthu zoyamba zomwe muyenera kuphunzira monga chitsanzo. Ngati muli 3D okwanira kuti simukudziwa momwe mungapangire mapepala a beveled, mwayi mutha kupindula ndi maphunziro abwino oyambirira kapenanso kulembetsa maphunziro .

Phunzirani Kugwiritsa Ntchito Mpukutu Woyambira
Ngakhale kuti ntchito yowonjezera yakhala ikuzungulira kwa zaka zambiri, idakali lingaliro losokoneza ndi lovuta kwa oyamba kumene. Ine sindiyesera kufotokoza kwathunthu chiphunzitso apa (pali zochuluka kwambiri kuti ndizinene), koma ine ndikufuna kuti ndiwonetsetse kuti inu mukudziwa bwino kuti njirazi ziripo.
Kufunika kwa ntchito yowonjezera kumatsimikizirika kuti chowonadi chanu chikuwonetsera zithunzi mu malo osiyanasiyana (sRGB) kuposa zomwe zimatuluka ndi injini yanu. Pofuna kulimbana ndi izi, akatswiri ojambula ayenera kutenga njira zofunikira kuti agwiritse ntchito makonzedwe a gamma .
Koma ntchito yeniyeni yeniyeni imapita kumalo osangalatsa kwambiri a gamma-zokhudzana ndi kuyesa njira zamakono ndi ntchito zomwe (zambiri zomwe zimachokera pa masamu osakhalitsa), ndikusunthira kumalo owona enieni.
Pali zambiri zomwe munganene ponena za ntchito yowonjezera, ndipo zowonjezera zakhala zikukambidwa bwino kwambiri m'zaka zingapo zapitazo. Pano pali chiyanjano chothandizira kuphunzira chiphunzitsochi pamapeto pake - amatha kufotokozera kuzinthu zochepa, kotero pali kuwerenga kochuluka koyenera kuchitidwa. Lumikizanani yachiwiri ndi maphunziro a Digital Tutors omwe amagwiritsa ntchito mzere wogwira ntchito mu Maya 2012.

Gwiritsani ntchito Mauthenga Ounika a IES a Photometric Lighting
Pogwirizana ndi kuwonjezeka kwa kayendedwe kake, ojambula zithunzi za 3D (makamaka omwe akugwira ntchito zojambula) ayamba kugwiritsa ntchito mafayilo omwe amawatcha kuti IES kuwala kuti afotokoze mozama zowala zenizeni.
Mapulogalamu a IES adalengedwa ndi opanga monga General Electric monga njira yowerengera chiwerengero chazithunzi. Chifukwa chakuti IES amawunikira mauthenga ali ndi zolondola zolongosola ponena za mawonekedwe a kuwala, kuwala, ndi kusowa. Otsatsa 3D adagwiritsa ntchito mwayi kuwonjezera thandizo la IES mu mapulaneti akuluakulu a 3D.
N'chifukwa chiyani mumathera maola kuyesera kutsanzira kuunika kwenikweni kwa dziko pamene mungagwiritse ntchito mbiri ya IES ndikukhala ndi chenicheni?
CG Arena ali ndi nkhani yabwino ndi zithunzi zabwino kukupatsani lingaliro la momwe mbiri ya IES ikuonekera.

Gwiritsani Ntchito Kuzama kwa Munda
Kuzama kwa munda (zovuta kumbuyo) zotsatira ndi imodzi mwa njira zosavuta zowonjezera zenizeni za malemba anu chifukwa ndi chinachake chomwe timayanjana kwambiri ndi kujambula moyo weniweni.
Kugwiritsira ntchito dothi lozama kwambiri kumathandiza kusiyanitsa nkhani yanu, ndipo kungakuthandizeni kuti mukhale ndi zida zowonjezereka pamene mukugwiritsidwa ntchito pazifukwa zoyenera. Zotsatira zakuya zikhoza kuwerengedwa kuti zimapereka nthawi kuchokera mu phukusi lanu la 3D, kapena likugwiritsidwa ntchito positumizira pogwiritsa ntchito z-depth pass and lens blur ku Photoshop. Kugwiritsa ntchito zotsatira pamsasa ndi njira yowonjezera, ngakhale kukhazikitsa kuya kwachonde mkati mwa pulogalamu yanu yoyamba kukupatsani mphamvu zambiri pa zotsatira.

Onjezerani Chromatic Abberation
Dzina likumveka lovuta, koma kuwonjezerapo chromatic kuberration kumasulira anu mwinamwake njira yophweka pa mndandandanda uwu.
Kuwonongeka kwa Chromatic kumachitika pazithunzi zojambula zenizeni pamene mandala imalephera kupereka njira zonse zojambula pamtundu womwewo. Chodabwitsachi chikuwonetseredwa ngati "zokopa zamitundu," kumene kumbali yayikulu yosiyana ikuwonetsera ndondomeko yofiira kapena yofiira.
Chifukwa chakuti ma chromatic aberration samachitika mwachibadwa ku CG kuunikira , ojambula 3D apeza njira zowonongera chodabwitsa mwa kuthetsa njira yofiira ndi ya buluu yomasuliridwa ndi pixel kapena awiri ku Photoshop
Kuwonongeka kwa Chromatic kungapangitse zowonjezera kutembenuza, komabe zingathenso kuchotseratu pamene zotsatira zatha. Musawope kuyesera izo, koma kumbukirani kuti wonyenga ndi bwenzi lanu lapamtima.
Monga ndanenera, kuperewera kwa chromatic ndi kokongola kosavuta kugwiritsa ntchito ndipo aphunzitsi a Digital ali ndi phunziro la mphindi ziwiri zaulere kuti akuwonetseni momwe:

Gwiritsani Mapu Odziwika
Ambiri mwa ojambula amaphunzira kugwiritsa ntchito mapu owonetsetsa bwino kwambiri, koma motsimikizirika amavomerezedwa kutchula aliyense yemwe sali pabwalo.
Mapu odziwika bwino amauza injini yanu zomwe zigawo zanu ziyenera kukhala zodziwikiratu (kutentha) ndi zomwe ziyenera kufalikira. Kugwiritsira ntchito mapu a specular kumaonjezera zowona chifukwa choti tiyang'ane nazo - zinthu zambiri zachilengedwe siziwonetsa mdima wonyezimira, koma mutachoka pamapu ovomerezeka, ndiye momwe chitsanzo chanu chidzaperekere.
Ngakhale zinthu zomwe zili ndi yunifolomu yonyezimira (zowonjezera zowonjezera, zowonjezereka) muyenera kugwiritsabe ntchito mapu kuti muthandize kuchotsa zosalala, zovunda, ndi zina.

Gwiritsani ntchito
Simukuwona "zolakwika za ungwiro" monga momwe munachitira m'masiku oyambirira a CG, koma kwa inu omwe mukufuna chithunzithunzi: musawope kuwonjezera dothi ndi kujambula zitsanzo zanu.
Zinthu zambiri zenizeni sizinali zoyera komanso zowoneka bwino, kotero kusiya mafano anu mwanjira imeneyo kungakhale ngati waulesi ndipo ndithudi kumachepetsa chikhumbo chanu chojambula chithunzi. Sikuti zimangokhala zolemba zamakono kapena kuyesa kuwonjezera ming'alu ndi chiwonongeko kwa ena a zitsanzo zanu, makamaka ngati mukugwira ntchito pa masewera a masewera a FPS.
Khalani ndi lingaliro la kukhala opanda ungwiro mu malingaliro pamene mukuwombera masewero anu. Pokhapokha ngati mukupita ku malo opangidwa opangidwa ndi opangidwa ndi opangidwa bwino kwambiri, perekani zofalitsa zina mwachilengedwe ponseponse kuti mupange malo omwe akuwonekera.

Onjezani Asymetry
Kukwanitsa kutembenuzira zofananitsa poyerekezera kapena kujambula chikhalidwe ndi zokongola kwambiri-zikutanthauza kuti monga otsogolera ife timangopanga theka la ntchito ndipo sitiyenera kudzidetsa tokha pokhapokha diso limodzi likukula kuposa linzake, kapena kutsimikizira kumanzere cheekbone ikugwirizana ndi yoyenera (mukudziwa, mavuto awo ovuta omwe amavutitsa ojambula ndi ojambula zithunzi).
Koma pakubwera nthawi yopanga tsatanetsatane ndikuyika chitsanzo chanu, ndizofunika kutseka kusinthasintha ndi kuwonjezera kusiyana kosiyana kwa khalidwe lanu.
Kaya zili muzovala, zovala, kapena mauthenga olembedwa, malemba, asymmetry amachititsa kuti zitsanzo zanu zizikhala ngati moyo, ndipo mwayi wanu mutha kukhala ndi chithunzi chomaliza komanso champhamvu kwambiri.
