Iindlela ezilula eziza kwenza ii-3D Renders zakho zenzeke ngakumbi
Ubungqina bezithombe-mnye ngenye yeenjongo eziphambili kubaculi abaninzi beCG, kwaye yinto enye enzima kunzima ukuyifumana. Nangona unomfanekiso omtsha kwiifayile zekhompyutheni ze-3D , kunjalo, izixhobo zanamhlanje kunye nobuchule bokusebenza emsebenzini zenza ukufunyanwa kwezithombe kufumaneka kakhulu. Nazi iindlela ezisibhozo zokukunceda ukuba ufike khona:

I-Bevel, Bevel, Bevel
Ukulibala ukuya kwiingqungquthela okanye kwiingqungquthela zenye iiposiso eziqhelekileyo ezenziwe ngabalingisi bokuqala be-3D. Kukho phantse i-razor-sharp sharp edge in nature, kwaye kunye nezinto ezininzi ezenziwe ngumntu zinomjikelezo omncinci apho zidibene khona. I-Beveling inceda ukuvelisa iinkcukacha, kwaye ngokuqinisekileyo uthengisa ngokoqobo imodeli yakho ngokuvumela iigqeba ukuba zibambe ngokugqithiseleyo iziphumo ezivela kwisisombululo sakho sokukhanyisa.
Ukusebenzisa i-bevel (okanye i sixhobo se-3ds Max) yenye yezinto zokuqala omele uzifunde njengomzekelo. Ukuba unomtsha okwaneleyo kwi-3D ukuba awuqinisekanga indlela yokwenza umgca ongezantsi, unako unako ukufumana inzuzo ngokwenene kwisifundo sokuqala esilungileyo okanye uqeqesho lokubhaliselwa .

Funda Ukusebenzisa Uluhlu olusebenzayo
Nangona i-flowar workflow iye yajikeleza iminyaka, kusengumxholo odidekayo kunye nobunzima kubaqalayo. Andiyi kuzama ukucacisa ngokupheleleyo le ngcamango apha (kuninzi nje ukuthetha), kodwa ndifuna ukuqinisekisa ukuba ubuncinane uyazi ukuba ezi zinto zikhona.
Isidingo somsebenzi ohambelana nomgca siza kuvela kwi nyaniso yokuba i-monitor yakho ibonisa imifanekiso kwisithuba sombala ohlukileyo (sRGB) kunokuba yintoni eyenziwa yi-injini yakho). Ukuze kulungiswe oku, ama-artists kufuneka athathe amanyathelo afanelekileyo ukuze asebenzise ukulungiswa kwe-gamma ukunikezela.
Kodwa uhambo olusebenzayo oluhambayo luhamba ngokugqithiseleyo kunokuba lulungelelaniso lwe-gamma elula-konke okubhekiselele ekusebenziseni ubuchule obudala kunye nokusebenza (ezininzi zazo ezisekelwe kwizibalo ezidlulileyo), kwaye zihambela kwizixazululo zokukhanyisa ezisemgangathweni.
Kukho okunye ukuthetha ngokuhamba komsebenzi, kwaye ngokubulela kuye kwaxutyushwa ngokubanzi kwiminyaka embalwa edlulileyo. Nasi isiqhagamshelo esibalulekileyo ekufundeni imbono emva kwenkqubo-idibanisa kwimithombo embalwa, ngoko kukho ukufunda okuninzi okumele kwenziwe. Ikhonkco yesibini yikhosi ye-Digital Tutors ejongene ngqo nomsebenzi ohamba phambili kumama wama-2012.

Sebenzisa iiprofayili zokukhanya ze-IES ze-Photometric Lighting
Ngaphandle kokunyuka komsebenzi ohambeneyo, abaculi be-3D (ingakumbi abo basebenzayo ekuboniseni izakhiwo) baye baqalisa ukusebenzisa iifayile ezibizwa ngokuba yi-IES zeprofayili zokukhanya ukuze zifane nokukhanya kwehlabathi.
Iiprofayili ze-IES zadalwa ngabenzi bezinto ezifana ne-General Electric njengendlela yokulinganisa idijithali yokukhanya kwedatha. Ngenxa yokuba iIES iiprofayili ezikhanyayo ziqulethe ulwazi oluchanekileyo lwephotometric malunga nokuma kwebala, ukukhanya kunye nokugqithisa. Abathuthukisi be-3D bathathe ithuba lokuncedisa i-IES inkxaso kwiiphakheji ezininzi ze-3D.
Kutheni uchitha iiyure uzama ukulinganisa ukukhanya kwehlabathi ngokwenene xa ungasebenzisa iphrofayli ye-IES kwaye unento yangempela?
I-CG Arena inomxholo omnandi kunye nemifanekiso emihle ukunika ingcamango yokuba iprofayili ye-IES ibonakala ngathi.

Sebenzisa ububanzi beNgingqi
Ubunzulu bentsimi (imvelaphi ephazamisekileyo) yinye yeendlela ezilula ukunyusa ukuzaliseka kwezinto zakho eziguqukayo kuba into esiyibambisene ngokusondeleyo kunye nezobugcisa bokuphila kwangempela.
Ukusebenzisa ubunzulu obunzulu benkalo kunceda ukuhlukanisa umxholo wakho, kwaye unokuphucula ukubunjwa kwakho ngokunyuka kunye nemida xa isetyenziswe kwiimeko ezifanelekileyo. Iziphumo ezinzulu zingabalwa ngexesha lokunikezela ngaphakathi kwiphakheji yakho ye-3D, okanye isetyenziswe kwimveliso yokuhamba emva kokupasa kwentsholongwane kunye ne-lens blur kwi-Photoshop. Ukusebenzisa isiphumo kwisithuba kukude kwindlela yokukhawuleza, nangona ukubeka ubunzulu bendawo ngaphakathi kwiprogram yakho eyinqobo kukunika ulawulo oluphezulu phezu kwefuthe.

Yongeza i-Abromation ye-Chromatic
Igama lizwakala luyinkimbinkimbi, kodwa ukongeza ukuchithwa kwe-chromatic kwi-renders yakho mhlawumbi yindlela elula kuloluhlu.
Ukuchithwa kwe-Chromatic kwenzeka kwi-real-world photography xa i-lens ihluleka ukunika zonke iziteshi zombala kwindawo enye yokuguquka. Le nto ibonakala ngathi "umbala ogqithiseleyo," apho uhlangothi oluphezulu lwahlukileyo lubonisa uluhlu olubomvu okanye oluhlaza okwesibhakabhaka.
Ngenxa yokuba i-chromatic aberration ayibonakali ngokwemvelo kwi-CG ukukhanyisa , abaculi be- 3D baye bathuthukisa iindlela zokufaka inkohlakalo ngokuqhekeza umzila obomvu nesibhakabhakeni wokunikezelwa ngephikseli okanye ezimbini kwi-Photoshop
Ukuchithwa kwe-Chromatic kunokuncedisa ukufezekiswa komsebenzi, kodwa kunokukhazamisa omnye xa umphumo ungaphezulu. Ungesabi ukuzama, kodwa khumbula ukuba ubuqhetseba ngumhlobo wakho omhle.
Njengoko ndathi, ukuchithwa kwe-chromatic kuhle kakhulu ukuba kusebenze kwaye i-Digital Tutors ine-minute yokufundisa yamahhala ukubonisa indlela:

Sebenzisa iMephu ecacileyo
Uninzi lwabaculi bafunda ukusebenzisa iimephu ezicacileyo ngokukhawuleza, kodwa ngokuqinisekileyo kufuneka ukuba kubhengezwe umntu ongekho ebhodini.
Iimephu ezicacileyo zitsho i-injini yakho apho iindawo zomzekelo wakho kufuneka zibe neengcamango eziphezulu (kunye ne-glossiness) kwaye zimele zenzeke ngakumbi. Ukusebenzisa amabalazwe angacacileyo ukwandisa ukubambezeleka ngenxa yokuba sijamelane nayo-izinto ezininzi kwimvelo azibonisi ukukhanya okufanayo, kodwa xa ushiya imephu ecacileyo, yiyo kanye indlela oza kuyenza ngayo.
Ngaphandle kwezinto ezinesigqabiso esifanayo (i-ceramics egqumbileyo, i-polished metal) kufuneka usebenzise imephu ecacileyo ukuze uncede ukukhupha izitenxo ezingaphezulu kwimiqwenga, imilo, kunye neentsimbi.

Grunge it Up
Awuboni "impazamo yokufezekisa" njengoko wenzayo kwiintsuku zakuqala zeCG, kodwa kulabo bafuna isikhumbuzo: musa ukoyika ukungenisa ukungcola kunye neentlobo zakho kunye nemifanekiso.
Uninzi lwezinto zehlabathi zangempela azihlambulukanga kwaye zincinci, ngoko ke ukushiya imizekelo yakho ngendlela enokuthi ivele njengezivila kwaye ngokuqinisekileyo iya kuphazamisa ukufuna kwakho ukulandelwa kwezithombe. Akufuneki nje ukuba ube neenkcukacha zetekisi okanye uzama ukufaka iintsikelelo ezinkulu kunye nokutshatyalaliswa kwamanye amanqaku akho, ngokukodwa xa usebenza kwiindawo zemidlalo zesitayela se-FPS.
Gcina ingcamango yokungaphelelanga engqondweni xa uphupha imifanekiso yakho. Ngaphandle kokuba uhamba nohlobo oluthile olubonakalayo olusisigxina lokubonisa izakhiwo, yichitha ezinye iiprogram ngokwemvelo kwimeko yakho ukwenza ukuba indawo ibonakale ihlala.

Yongeza i-Asymetry
Ukukwazi ukuvula umlinganiso xa ukufanekisa okanye ukutyhila umlingisi kuyinto ephathekayo enkulu-kuthetha ukuba njengabalingisi kuphela kufuneka senze isigamu somsebenzi kwaye singalokothi sizikhathaze ngaphezu kwelinye iliso likhulu kunomnye, okanye uqinisekise ukuba ikhohlo i-cheekbone idityaniswe kunye nelungileyo (uyazi, ezo iingxaki ezinzima ezikhathazayo abadwebi bendabuko kunye nabadwebi).
Kodwa xa kufika ixesha lokuba wenze inkcazelo yokugqibela kwaye ubeke imodeli yakho, ingcamango enkulu yokucima umlinganiso kwaye ungeze uhlobo oluthile lokungafani komlingiswa wakho.
Ingaba kukho kwi-pose, iingubo, okanye iinkcukacha zeteknoloji, i-asymmetry iya kwenza imizekelo yakho ibe yinto efana nobomi, kwaye amathuba okugqibela uza kugqiba ngesithombe esiphezulu nesiphumeleleyo sokugqibela.
