Izindlela Elula Ezizokwenza Abanikazi Bakho Baka-3D Bangene Ngempela
Ukubukwa kwesithombe kungenye yezinhloso zokugcina abaculi abaningi be-CG, kanti futhi kunenye yezinzima kakhulu ukufeza. Ngisho noma ngabe uyingqayizivele kwihluzo zekhompyutha ye-3D , noma kunjalo, amathuluzi anamuhla namasu okuhamba komsebenzi enza ubuciko bezithombe obutholakala kakhulu. Nazi izindlela eziyisishiyagalombili zokusiza ukuthi ufike lapho:

Bevel, Bevel, Bevel
Ukukhohlwa ukuthi i-bevel noma i-chamfer edges ingenye yeziphambeko ezivame kakhulu ezenziwa abaculi be-3D. Kukhona cishe amaphethelo abukhali emiphakathini, futhi ngisho nezinto eziningi ezenziwa abantu zinokujikeleza okuncane lapho kuhlangana khona izindawo ezimbili eziphikisanayo. I-Beveling isiza ukuveza imininingwane, futhi idayisa ngempela imvelaphi yemodeli yakho ngokuvumela imiphetho ukuthi ibambe ngokucacile amaphuzu avelele kusuka kusixazululo sakho sokukhanyisa.
Ukusebenzisa i-bevel (noma i-chamfer Ithuluzi ku-3ds Max) ingenye yezinto zokuqala okufanele uzifunde njengomodeli. Uma ususha ngokwanele ku-3D ukuthi awuqiniseki ukuthi ungakha kanjani umkhawulo we-beveled, kungenzeka ukuthi uzuze ngempela esifundweni esihle sokuqala noma ngisho nokubhaliswa kokuqeqeshwa .

Funda Ukusebenzisa Ukuhamba Kokusebenza Okukodwa
Ngisho noma ukuhamba komsebenzi okulinganayo kuye kwadlula iminyaka, kusengumqondo odidekayo futhi onzima woqalayo. Ngeke ngizame ukuchaza ngokuphelele le mbono lapha (kuningi kakhulu ongakusho), kodwa ngifuna ukuqinisekisa ukuthi okungenani uyazi ukuthi lezi zindlela zikhona.
Isidingo sokwenziwa komsebenzi okulinganiselwe sifike ekugcineni ukuthi umqaphi wakho ubonisa izithombe endaweni ehlukile yombala (sRGB) kunalokho okwenziwe yi-injini yakho. Ukuze silwisane nalokhu, abaculi kumele bathathe izinyathelo ezidingekile zokusebenzisa ukulungiswa kwe-gamma ukuze banikele.
Kodwa ukuhamba kahle komsebenzi kuhamba kahle kakhulu kunezingubo ezilula ze-gamma-kungcono mayelana nokuhlola amasu amadala nokusebenza okudala (okuningi okusekelwe kwizibalo ezingaphelelwe yisikhathi), futhi ukuthuthela ezimpambanweni zokukhanyisa ezisekelwe ngokomzimba ngokomzimba.
Kukhona okuningi okushoyo mayelana nokuhamba komsebenzi ohambene, futhi ngokuthokoza kukhulunywe kabanzi ngokweminyaka embalwa edlule. Nansi isixhumanisi esiwusizo sokufunda inkolelo ngemuva kwenqubo-uhlanganisa imithombo embalwa, ngakho-ke kunokuningi okufundwayo okumele kwenziwe. Isixhumanisi sesibili yinkambo ye-Digital Tutors ephathelene ngqo nokusebenza okuhambisanayo kuMaya 2012.

Sebenzisa Amaphrofayela we-IES Light for Photometric Lighting
Ngaphandle kokuphakama komsebenzi ohambisanayo, abaculi be-3D (ikakhulukazi labo abasebenza ekubukeni kwezakhiwo) baqale ukusebenzisa amafayela abizwa ngokuthi amaphrofayli e-IES ukukhanya ngokulinganisa ukukhanya kwezwe langempela.
Amaphrofayela we-IES ekuqaleni adalwe abakhiqizi abanjengoGener Electric njengendlela yokulinganisa idatha ye-photometric yokukhanyisa. Ngenxa yokuthi amaphrofayili we-IES amancane aqukethe ulwazi olunembile lwe-photometric mayelana nokuma okukhanyayo, ukukhanya nokulala. Abathuthukisi be-3D bathathe ithuba lokufaka ukwesekwa kwe-IES kumaphakheji amaningi amakhulu e-3D.
Kungani uchitha amahora uzama ukulingisa ukukhanya kwezwe langempela uma ungasebenzisa iphrofayili ye-IES futhi unento yangempela?
I-CG Arena inesihloko esihle ngezinye izithombe ezinhle ukukunika umbono wokuthi iphrofayela ye-IES ekhanyayo ibonakala kanjani.

Sebenzisa ukujula kwensimu
Ukujula kwensimu (imiphumela engemuva engemuva) yinye yezindlela ezilula zokwandisa ubuqiniso bezinguquko zakho ngoba into esizihlanganisa eduze nokuphila kwangempela kwezithombe.
Ukusebenzisa ukujula kwensimu okungajulile kusiza ukuhlukanisa indaba yakho, futhi kungathuthukisa ukubunjwa kwakho ngokukhipha imifino nemingcele lapho isetshenziselwa izimo ezifanele. Imiphumela yokujula ingabalwa ngesikhathi sokunikeza ngaphakathi kwephakheji yakho ye-3D, noma isetshenziswe ekuthumeni kokukhiqizwa usebenzisa ukudluliswa okujulile kwe-z-lens kanye ne-lens blur ku-Photoshop. Ukusebenzisa umphumela kokuthunyelwe kungumzila osheshayo, kepha ukubeka ukujula kwensimu ngaphakathi kohlelo lwakho lokusebenza oluyinhloko kukunika ukulawula ngaphezulu komphumela.

Engeza ukuphanga kwe-Chromatic
Igama lizwakala luyinkimbinkimbi, kodwa ukwengeza ukuchithwa kwe-chromatic kuya ku-renders yakho cishe kuyindlela elula kulolu hlu.
Ukwehliswa kwe-Chromatic kwenzeka emifanekisweni yezwe langempela lapho i-lens ihluleka ukunikeza zonke iziteshi zombala endaweni eyodwa yokuguquguquka. Lesi senzakalo sibonakala njengokuthi "umbala ogqamile," lapho izingqimba eziphambene kakhulu zibonisa uhlaka olubomvu noma oluhlaza okwesibhakabhaka.
Ngenxa yokuthi ukuchithwa kwe-chromatic akuveli ngokweqile ku-CG ukukhanyisa , abaculi be-3D baye bahlakulela izindlela zokufaka iphutha lesi senzakalo ngokuqeda isiteshi esibomvu nesibhakabhakeni sokunikeza i-pixel noma amabili ku-Photoshop
Ukwehliswa kwe-Chromatic kungangezelela ukubuyisela okuyiqiniso, kodwa kungaphinde kuphazamise omunye lapho umphumela usuphelile. Ungesabi ukukuzama, kodwa khumbula ukuthi ubuqili ungumngane wakho omkhulu.
Njengoba ngishilo, ukuchithwa kwe-chromatic kuhle kakhulu ukuthi kusetshenziswe kalula futhi i-Digital Tutors ine-free minute yokufundisa ukuze ikubonise ukuthi:
Umhlahlandlela Obonakalayo Wokungena Kwe-Chromatic

Sebenzisa i-Maps Specular
Abaningi be-artists bafunda ukusebenzisa amabalazwe acacile kahle kakhulu, kodwa ngokuqinisekile kudingeke ukuba kukhulunywa nganoma ubani ongasekho ebhodini.
Amabalazwe angacacile atjela injini yakho ukuthi yiziphi izingxenye zesimodeli sakho okufanele zibe nokucatshangelwa okuphezulu (okucwebezelayo) futhi okumele kube nokusabalalisa kakhulu. Ukusebenzisa amabalazwe acacile ukwandisa ubuqiniso ngoba kufanele sibheke-izinto eziningi emvelweni azibonisi ukukhanya okufanayo, kodwa uma ushiya imephu ecacile, yiyo kanye indlela oyisibonelo sakho esizoyihlinzeka ngayo.
Ngisho nezinto ezinesisindo esifanayo (i-ceramics eluhlaza, i-polished metal) kufanele usasebenzise imephu ecacile ukuze usize ukuveza ukungalungi okuvela emanzini, ukudonsa, kanye namazinyo.

Gcina it Up
Awuboni "iphutha lokuphelela" okuningi njengoba wenza ezinsukwini zokuqala ze-CG, kodwa kulabo abadinga isikhumbuzi: ungesabi ukwengeza ukungcola nokufaka amafoni akho kanye nokuthungwa kwakho.
Izinto eziningi zangempela-zezwe azihlanzekile futhi zihlanzekile, ngakho-ke ukushiya amamodeli akho ngale ndlela kungabonakala njengobuvila futhi ngokuqinisekile kuzokwehlisa isifiso sakho sokubukeka kwesithombe. Akudingeki ukuba kube yimininingwane yombhalo noma-zama ukungeza ukuphazamiseka okukhulu nokubhujiswa kwamanye amamodeli akho, ikakhulukazi uma usebenza ezindaweni zezemidlalo zesitayela se-FPS.
Gcina umqondo wokungapheleli engqondweni uma usakaza izigcawu zakho futhi. Ngaphandle kokuthi uya endaweni yobuciko obuhle kakhulu yokwakhiwa kwezakhiwo, phakamisa ezinye izasesheli ngokuzenzakalelayo kuyo yonke indawo yakho ukuze wenze isikhala siphile.

Engeza i-Asymetry
Ikhono lokuvula i-symmetry uma ukufanekisa noma ukudweba umlingisi kuyinto yokunethezeka enkulu-kusho ukuthi njengabafanisi kufanele senze ingxenye yesiqephu somsebenzi futhi singalokothi sikhathazeke ngokweqile iso elilodwa likhulu kunelo, noma siqiniseke ukuthi kwesokunxele i-cheekbone ihambisana nomunye ofanele (uyazi, lezo zinkinga ezinzima ezihlupha abadwebi bendabuko nabadwebi).
Kodwa uma kufika isikhathi sokuba wenze imininingwane yokugcina idlule bese ubeka imodeli yakho, kungumqondo omuhle ukucima ukulinganisa futhi wengeze uhlobo oluthile lokuhluka kwe-asymmetric kumlingisi wakho.
Kungakhathaliseki ukuthi ku-pose, i-costume, noma imininingwane ye-textural, i-asymmetry izokwenza ama-model akho abe nempilo efana nempilo, futhi amathuba azophela ngesithombe esiphezulu nesiphumelele sokugcina.
