Iimephu zeemoto ze-3D zimephu ezisetyenziswe kwi-3D modeling ukuze zenze ngokucacileyo imifanekiso ephakanyisiweyo ngaphandle kokuba ifake imodeli nganye. Ukuzama ukubonisa iimpawu ezicacileyo kunokudala umonakalo wee-polygons ezongezelelweyo, ukwandisa ixesha lokubonisa imodeli, ukudala imodeli engabonakaliyo, nokwandisa ixesha lokunikezela kunye nokusetyenziswa kwamandla kwiimali ezingenangqondo. Ngaphandle kwezinto ezibonakalayo ze-3D, nangona kunjalo, imodeli ye-3D ibonakala ngathi iyicala kwaye ayikho.
Iimephu zeemoto ziyimpendulo; zilahla phantsi kwebala elipheleleyo lemibala yokupenda, sebenzisa i-grayscale ukuxelela iinkqubo ze-3D zokumisela indlela ekude zenzeke ngayo iipoloniyali, kunye nomnyama obonisa ukugqithisa okuphezulu kakhulu kunye nemhlophe emele indawo ezintle kakhulu, ngelixa i-gray shade ibonisa amanani phakathi. Ngokomzekelo, ukuba ubethetha ngetekisi yesikhumba, imephu yephunga yesikhumba ingasebenzisa i-gray-level level njengomgca wesiseko kwesikhumba, enezimhlophe eziqhekekileyo kunye nezindawo ezimnyama ezimnyama ezimele indawo, konke oku ngaphandle kokwenza umzekelo omnye okanye ukuhlahlela. Ungayisebenzisa nokuba wenze iziqwenga zobuso kunye nezithunzi zibonakala zichanekile, okanye zongeze iinkcukacha ezifana neentlobo kunye nemibango kwiimpahla zembatho okanye izixhobo.
Yindlela elula yokongeza iinkcukacha ezininzi ngaphandle kokongeza umsebenzi omningi. Kunokuba ufune ukungena ngesandla uze ukhethe yonke into encinane ukuba uhambe kumzekelo wakho, imephu yephunga iyakwenza i-automate inkqubo yakho. Kuza kuxela inkqubo ye-3D ukutshintsha iipolgoni ngokubhekiselele kwimephu yakho yephunga kunokuba ufanele uyenze ngokwakho. Kwakhona kwenzelwa okokusebenza, oku kunokukunceda ukunciphisa umthwalo kwikhompyutheni xa kuhamba ukunikezela ukuba ungene kwaye wenza zonke ezo zibopho kwaye uzibambe.
Ukudala imephu ephosakeleyo kwi-Photoshop kulula, ngakumbi ukuba sele udale imephu yokuthutha kunye neenkqayila kunye nezithunzi ezidwetshwe ngombala. Amanyathelo amundoqo:
- Nceda uvule imephu yakho yohlobo lwemibala okanye udale enye kwi-Photoshop usebenzisa izixhobo zokupenda. Ukuba ukhangele ukwenziwa kobugcisa kwaye awukho into efana ne-shading facial, ungasebenzisa izitayela zokubala ezifana ne-Pattern Overlay ukuze uvelise ukuthungwa. Ingcaciso ecaciswe ngokucacileyo, uya kufuna imephu echanekileyo ukuze uqiniseke ukuba iziqulatho zemibala kunye neethunzi zihamba ngokuhambelana nokuthungwa kwemephu ye-mapping.
- Gcina ikopi ye- grayscale yemephu. Ukuguqula umbala wemibala kwi-grayscale version, sebenzisa umsebenzi weDesaturate phantsi kweMifanekiso-> Imenyu yokulungiswa. Ukuba uvelise ukutyunjwa kwakho usebenzisa izitala zokubeka kunye neepatheni, ungadinga ukucwangcisa uluhlu ukuze ulungiso lwakho luchaphazele ukubunjwa kwaye kungekhona nje umbala osezantsi.
- Ngokuxhomekeke kwindlela oye wenziwe ngayo, ungadinga ukuguqula umfanekiso. Kwimibala yokuqala yombala oye wawafaka ngayo imizobo emnyama, kunye neendawo eziphakamileyo ziza kukhanya ngakumbi, zichazwe ngokukhanya / ithoni kwi-shading. Kwimephu yephunga, kodwa iindawo ezikhanyayo ziphantsi xa iindawo ezimnyama ziphezulu, ngoko ukushiya njengokuba-kuya kudala umphumo ochasene nento oya kuyo: izifuba eziphakanyisiweyo kunye neengqungquthela ezikhanyayo. Unokufumana umsebenzi wokuguqula endaweni efanayo ufumene umsebenzi weDesaturate, phantsi kweMifanekiso -> Imenyu yokulungiswa.
- Ungadinga ukucima imephu yephunga ukuze ukwandise ukuhluke phakathi kweendawo ezikhanyayo kunye neendawo ezimnyama. Ukusebenzisa njengalo-kungenakho ukudala ubunzulu beenkcukacha ozifunayo kwi-texture yakho. Ungasebenzisa isixhobo soBhanya / Isiqhamo phantsi koMfanekiso -> Imenyu yokulungiswa ukuze uhlaziye umfanekiso kwaye ukwandise ukuhluke.
- Gcina i fayili - mhlawumbi kwifomati engenakulahlekelwa ngezinga eliphezulu leenkcukacha, njenge-BMP / bitmap, nangona uya kufuneka ukuba uhlole inkqubo yakho ye-3D yokwenza ifomati yokuhambelana.
Emva kokuba udale imephu yakho yephunga, konke okufuneka ukwenze kukungenisa kwiprogram yakho yefayile ye-3D. Iinkqubo ezahlukeneyo zineendlela ezahlukileyo zokudibanisa iimephu zeemephu kwiimodeli okanye kwi-polygon surface, kodwa ukulawulwa kwemephu yephunga kufuneka kukuvumele ukuba uchaze uluhlu ukuqinisekisa ukuba ukuphakanyiswa kweempawu kunye nokuxothwa akunakugqithisi ukugqithisa okanye ukunciphisa kakhulu a ba bonisi. Imephu yephunga isisityebi esihle kakhulu xa kufikelelwe ekungenizeni iinkcukacha ezininzi ngaphandle kokongeza umsebenzi omningi.
