Amabalazwe we-3D bump amamephu asetshenziselwa ukufaniswa kwe-3D ukwenza ngokuzenzakalela ukudala imidwebo ephakanyisiwe ngaphandle kokufanekisa imininingwane ngayinye. Ukuzama ukulinganisa ukufakwa kwemininingwane okuningiliziwe kungadala izinqwaba zamapoloni amaningi, ukwandise isikhathi sokwenza imodeli ngokucacile, ukudala onobuhle obungenangqondo, futhi ukwandise isikhathi sokuhlinzeka nokucubungula amandla kumanani angenangqondo. Ngaphandle kwemidwebo ye-3D engokoqobo, noma kunjalo, amamodeli e-3D angabheka njengezicabha futhi angenampilo.
Amabalazwe we-Bump yimpendulo; zihlelwe phansi ngaphansi kwamabalazwe okudweba okugcwele okudweba umbala, sebenzisa ama-grayscale ukutshela izinhlelo ze-3D zokufometha ukuthi yikude kangakanani ukukhipha izakhiwo ze-polygonal, omnyama obonisa ukugqama okukhulu kakhulu kwe-extrusion nomhlophe obamele izindawo ezihlabayo, kanti ama-shades of gray amelela amamaki aphakathi. Isibonelo, uma ubhalela isikhumba somlutha, i-map bump yesikhumba ingasebenzisa i-gray-level level njengendlela eyisisekelo ebusweni besikhumba, enezimhlophe ezikhungweni ezijulile nezindawo ezimnyama ezimnyama ezimele izindawo eziphakanyisiwe, konke lokhu ngaphandle kokulinganisa i-bump eyodwa noma ukuphahlazeka. Ungayisebenzisa futhi ukwenza amaphuzu avelele ebusweni kanye nezithunzi kubonakale kungokoqobo, noma wengeze imininingwane enjengamafolda nama wrinkles ezembatho noma izikhali zemodeli.
Yindlela elula yokwengeza imininingwane eminingi ngaphandle kokufaka umsebenzi omningi. Esikhundleni sokuthi ungena ngesandla bese ukhetha yonke into encane ukuze uphume kumamodeli wakho, imephu ye-bump izokwenza inqubo kuwe. Izotshela uhlelo lwe-3D lokushintsha ama-polygons maqondana nebala lakho le-bump kuwe kunokuba wenze lokho ngokwakho. Kubuye kwenzeke ngendlela yokwenza, okungasiza ekunciphiseni umthwalo kwikhompyutha uma kuphuma ukuyikhipha uma ungene futhi wenza zonke lezo zibopho bese uzivimbela.
Ukudala imephu ye-bump ku-Photoshop kulula, ikakhulukazi uma usuvele udale imephu yokuthungatha ngamaphuzu avelele nemithunzi edwetshwe ngombala. Izinyathelo eziyisisekelo:
- Noma uvule imephu yakho yokudweba enemibala noma udale eyodwa ku-Photoshop usebenzisa amathuluzi okupenda. Uma nje ufuna ukwakheka okujwayelekile futhi hhayi okuthile okufana nokuthungatha ubuso, ungasebenzisa izitayela zokungqimba ezifana ne-Overlay Pattern ukuze kuvezwe ukuthungwa okuphindaphindiwe. Ukuze uthole imininingwane eqoshwe ngokuqondile, uzodinga imephu eqondile ukuze uqiniseke ukuthi izici ezigqamile zemibala nezithunzi zihambisana ne-bump yokuthungwa kwe-mapping.
- Londoloza ikhophi ye- grayscale yemephu. Ukuvula inguqulo yombala ibe inguqulo ye-grayscale, sebenzisa umsebenzi we-Desaturate ngaphansi kweMifanekiso -> imenyu yokulungiswa. Uma usukhiphe ukuthungwa kwakho usebenzisa izitayela zezendlalelo namaphethini wephethini, kungase kudingeke ukuba ubeke phansi ungqimba ukuze ukulungiswa kwakho kuthinte ukuthungwa hhayi nje umbala wesisekelo ngaphansi.
- Kuye ngohlobo lomthunzi owenzile, kungase kudingeke ukuguqula isithombe. Emgqeni wobunjalo bokuqala ubuzobe udwebe izithunzi zibe mnyama, futhi izindawo eziphakeme kakhulu zizocaca, zivuleke ekukhanyeni / ithoni ekuthunjweni. Emabalazweni we-bump, izindawo ezikhanyayo ziphansi uma izindawo ezimnyama ziphakeme, ngakho-ke ukushiya njengo-kungenza umphumela ohlukile kulokho oya khona: izimo eziphakanyisiwe kanye nokugqama okukhanyayo. Ungathola umsebenzi wokuguqula endaweni efanayo uthola umsebenzi we-Desaturate, ngaphansi kweMifanekiso -> Imenyu yokulungiswa.
- Kungase kudingeke ukuthi uhlele imephu ye-bump ukuze ukwandise umehluko phakathi kwezindawo ezikhanyayo nezinnyama. Ukusebenzisa njenge-kungase kungadala ukujula kwemininingwane oyifunayo ekuthungeni kwakho. Ungasebenzisa ithuluzi lokugqama / lokugqama ngaphansi kweMifanekiso -> Imenyu yokulungiswa ukuze ukhulise isithombe bese ukwandisa umehluko.
- Londoloza ifayela - mhlawumbe ngesakhiwo esingenasici nezinga eliphezulu lemininingwane, njenge-BMP / bitmap, noma uzodinga ukuhlola uhlelo lwakho lwe-3D lokuhambisana kwefomethi yesithombe.
Uma usungule imephu yakho ye-bump, konke okudingeka ukwenze kungenisa ngaphakathi ohlelweni lwakho lwezithombe ze-3D. Izinhlelo ezehlukene zinezindlela ezahlukene zokuhlanganisa amabalazwe abe yizibonelo noma i-polygon surface, kodwa ukulawula kwebalazwe elimele kufanele likuvumele ukuthi uchaze ibanga ukuze uqiniseke ukuthi imidwebo ephakanyisiwe kanye nokuthungwa akukhiphi ngokweqile noma ukwehlisa phansi kakhulu kangangokuthi ababonisi neze. I-map bump iyithuluzi elihle kakhulu uma kuziwa ekungeza imininingwane eminingi ngaphandle kokwengeza umsebenzi omningi.
