Ukuthi Amabalazwe Amathambo Awenziwe kanjani
Lesi sihloko siyingxenye yesibili ochungechungeni lwethu ekuvukeni . Isigaba sokuqala sihlanganisa ukudala ukuhlelwa kwe-UV yesimo se-3D. Manje sizobuka ukumeleka kwemephu.
Ngakho-ke Umephu Yamagama Obani?
Ibalazwe lokuthutha liyifayela lesithombe ezimbili-ntathu elingasetshenziswa ebusweni befomethi ye-3D yokwengeza umbala, ukuthungwa, noma enye imininingwane ebonakalayo njengobungqingili, ukubukeka, noma ukubonakala. Ukuthungwa kwamamephu kuthuthukiswa ukuze kuhambelane ngqo nezixhumanisi ze-UV ze-model ye-3D engavaliwe futhi zihlelwe kusuka ezithombeni zangempela-ukuphila, noma zidwebe ngesandla kwisicelo sehluzo njenge-Photoshop noma i-Corel Painter.
Ukumisa amamephu ngokuvamile kudwetshwe ngokuqondile kwesakhiwo se-UV somfanekiso, esingathunyelwa njengesithombe se-bitmap esivela kunoma iyiphi iphakethe le-software ye-3D . Ukudweba abaculi ngokuvamile basebenza emafayeleni ahlambulukile, ngezixhumanisi ze-UV emgqeni ongenawo obala ukuthi umculi uzosebenzisa njengomhlahlandlela wendawo yokubeka imininingwane ethile.
Umbala (noma usakaza) Amamephu
Njengoba igama lingafakazela, ukusetshenziswa okusobala kakhulu kwebalazwe lokuthungwa ukufaka umbala noma ukuthungwa phezu komfanekiso . Lokhu kungaba okulula njengokusebenzisa ukuthungwa kokusanhlamvu kwezinkuni endaweni etafuleni, noma njengeyinkimbinkimbi njengebalazwe lembala lomuntu wonke uhlamvu lomdlalo (kufaka phakathi izikhali nezesekeli).
Kodwa-ke, igama lemephu yokuthungwa kwegama, njengoba lisetshenziselwa ukujwayela ibalazwe elincane elibhekene ne-misnomer-play iqhaza elikhulu kwihluzo zekhompyutha ngaphandle kombala nokuthungwa. Esimweni sokukhiqiza, uhlamvu lombala noma imephu yombala ngokuvamile luyodwa yamamephu azosetshenziswa cishe kuwo wonke ama-3D oyimodeli.
Eminye imidwebo emibili "ebalulekile" imephu ngamamephu we-specular ne-bump, displacement, noma amamephu ajwayelekile.
Amamephu okucacisiwe
Amabalazwe angacacisiwe (eyaziwa nangokuthi amabalazwe aphezulu). Ibalazwe elicacile litshela isofthiwe ukuthi yiziphi izingxenye zesimodeli okumelwe zikhanyise noma zibe mnandi, futhi ubukhulu be-glossiness. Amabalazwe angacacisiwe abizwa ngokuthi izindawo ezikhanyayo, njengezinsimbi, izitshalo ze-ceramics, namanye ama-plastiki abonisa ukugqamisa okuqinile okucacile (ukuveza ngokuqondile umthombo okhanyayo). Uma ungaqiniseki ngamaphuzu avelele we-specular, bheka ukubonakala okumhlophe emgqeni wegayi lakho lekhofi. Esinye isibonelo esivamile sokucabangela okucacile ukukhanya okuncane emhlophe kweso lomuntu, ngenhla ngaphezu komfundi.
Ibalazwe elicacile ngokuvamile liyisithombe se-greyscale futhi kubaluleke kakhulu ezindaweni ezingafani kahle. Imoto eyisikhali, isibonelo, idinga imephu ecacile ukuze kukhishwe imivimbo, amazinyo, nokungafezeki kwezikhali ukuze kutholakale ngokuqiniseka. Ngokufanayo, umlingisi wegeyimu owenziwe ngezinto eziningi angadinga imephu ecacile ukuze adlulise amazinga ahlukene okugcoba phakathi kwesikhumba somlingisi, isikhumba sensimbi yensimbi kanye nezinto zokugqoka.
Bump, Displacement, noma Imephu evamile
Okuyinkimbinkimbi kakhudlwana kuneyodwa yezibonelo ezimbili zangaphambilini, amamephu we-bump ahlobo lwebalazwe lokuthungatha elingasiza ukunikeza ukubonisa okungokoqobo kwamabhomu noma ukuphonswa ngaphezulu kwesimo.
Cabanga ngodonga lwezitini: Isithombe sodonga lwezitini singabhalwa ku-plane yendiza ebizwa ngokuthi i-polygon plane futhi kuthiwa iphelile, kodwa amathuba okungeke abuke kakhulu ekukhokheni kokugcina. Lokhu kungenxa yokuthi indiza yendiza ayiphenduli ngokukhanyisa ngendlela efanayo nodonga lwamazitini oluyokwenza, ngokuphazamiseka kwalo nokushayeka.
Ukwandisa umbono weqiniso, i-bump noma imephu evamile ingezwa ukuze kulungiswe kabusha ngokunembile ubuso obunzima, obunobuningi bezitini, futhi kukhulise ukukholelwa ukuthi ukuchohloka phakathi kwezitini empeleni kuvele endaweni. Yiqiniso, kungaba khona ukufeza umphumela ofanayo ngokufanisa zonke izitini ngesandla, kodwa indiza evamile ehlelwe imephu isebenza kahle kakhulu. Akunakwenzeka ukudlula ukubaluleka kokumeka okujwayelekile embonini yamanje yemidlalo-imidlalo ayikwazanga ukubuka indlela abenza ngayo namhlanje ngaphandle kwamabalazwe avamile.
I-Bump, ukufuduka, namabalazwe avamile kukhona ingxoxo ngokwabo ngokufanele futhi kubaluleke kakhulu ekufezeni isithombe-ubuqiniso ekunikeleni .
Qaphela ukuthi isihloko sibheke ngokujulile.
Eminye Imephu Imephu Yokukwazi
Ngaphandle kwalezi zinhlobo ezintathu zemephu, kukhona omunye noma ababili ozobona ngokuvame kakhulu:
- Ibalazwe lokuzindla: Utshela isofthiwe ukuthi yiziphi izingxenye ze-3D model okufanele zibonise. Uma yonke indawo yesimodeli ibonakala, noma uma izinga lokubonakalisa lifana nebalazwe elivame ukushiywa. Amabalazwe okuzindla yizithombe zemigodi, obumnyama obonisa u-0% ukubonakaliswa nokukhanya okumhlophe okubonisa ubuso obunamaphesenti angu-100.
- Ukungabonakali Imephu: Ngokuqondile kufana nebalazwe lokubonisa, ngaphandle kokuthi litshela isofthiwe ukuthi yiziphi izingxenye zesimodeli okufanele zibonakale. Ukusetshenziswa okuvamile kwebalazwe obala kungaba yinto engaba nzima kakhulu, noma ebiza ngokuphindaphindiwe kakhulu ukuphindaphindiwe, njengocingo lwesikhungo sokuxhumanisa. Ukusebenzisa ukukhanya, esikhundleni sokufanisa izixhumanisi ngabanye kungaba yinto eqinisekisayo uma nje umodeli ungabonakali kakhulu eduze, futhi isebenzisa amapoloni ambalwa kakhulu.
Sibheke ukudala nokubeka ngaphandle kwe-UVs futhi sibheke ngezinhlobo ezahlukene zamabalazwe angaphezulu angasetshenziswa kumodeli we-3D. Uhamba kahle endleleni yakho ukuze ufike phezu kwesimo sakho se-3D!
