Indlela Iimpawu zeMephu ezenziwe ngayo
Eli nqaku liyinxalenye yesibini kwinqaku lethu ekuhambeni. Icandelo lokuqala libandakanya ukudala udidi lwe-UV lwemodeli ye-3D. Ngoku siza kujonga imephu yokubhala.
Ngoko Imephu Yendlela Yokubhala?
Imephu yendlela yokwenza imfayile ifayile yesibini efana nesimo esingasetyenziswa kumgangatho we-3D imodeli yokongeza umbala, ukubunjwa, okanye ezinye iinkcukacha zobuso njenge-glossiness, reflectivity, okanye transparency. Iimephu zeempawu ziphuhliswa ukuba zihambelane ngqo ne-UV izikhokelo zemizekelo ye-3D engaqanjwanga kwaye zicwangciswe kwiifoto zobomi bokwenene, okanye zenziwe ngezandla kwiifayile ezifana ne-Photoshop okanye iCorel Painter.
Ukuthambisa imephu ngokuqhelekileyo kudwetshwe ngokuthe ngqo phezulu kwendlela yokwakhiwa kwe-UV, enokuthi ithunyelwe njengemifanekiso yesikhala se-bitmap kwiyiphi na iphakheji yeprogram ye-3D . Ukugqithwa kwamatriki ngokuqhelekileyo kusebenza kwiifayile ezikhethiweyo, kunye ne-UV izikhokelo kumgca ongasese obala oza kuwusebenzisa njengesikhokelo sokuba ubeke khona iinkcukacha ezithile.
Umbala (okanye usasaza) Iimephu
Njengoko igama liyakubonisa ukuba, ukusetyenziswa okucacileyo kwimephu yokuthutha kukufaka umbala okanye ukuthungca kumgangatho womzekelo . Oku kungenza kube lula njengokusebenzisa umgubo wokutya okusanhlamvu kumgangatho wetafile, okanye unzima njengemephu yembala yomdlalo womdlalo wonke (kuquka iinqwelo kunye nezixhobo).
Nangona kunjalo, igama leemephu imephu , njengoko isoloko isetyenzisiweyo i-maps of surface mismomer idlala indima enkulu kwimifanekiso yecomputer ngaphandle kombala kunye nokuthungwa. Kwimimiselo yokuvelisa, umgca okanye umbala webala lombala ngokuqhelekileyo yiyodwa yemaphu emithathu eya kusetyenziselwa phantse yonke imodeli enye ye-3D.
Eminye imimiselo emibini "ebalulekileyo" imephu imephu ecacileyo kunye nebala, ukufuduka, okanye iimephu eziqhelekileyo.
Iimephu ezicacileyo
Iimephu ezicacileyo (eyaziwayo njengeimephu zeplastiki). Imephu ecacileyo ichaza isofthiwe apho iindawo zemizekelo kufuneka zikhanyise okanye zicwebezele, kunye nobukhulu be-glossiness. Iimephu ezicacileyo zibizwa ngokuba yizinto ezikhanyayo, njengezinyithi, ii-ceramics, kunye nezinye iiplastiki zibonisa ukugqithisa okuqinileyo (umboniso othe ngqo ukusuka kumthombo okhanya ngamandla). Ukuba awuqinisekanga malunga neengqungquthela ezibonakalayo, jonga umboniso omhlophe kwisigxina somgudu wakho wekhofi. Omnye umzekelo oqhelekileyo wokubonakalisa okucacileyo yincinci emhlophe kumntu othile, ngaphezu komfundi.
Imephu ecacileyo ngokuqhelekileyo imifanekiso ye-greyscale kwaye ibaluleke kakhulu kwiindawo ezingafani ngokugqithiseleyo. Imoto ekhuselekileyo, umzekelo, ifuna imephu ecacileyo ukwenzela ukuba imirhubhe, iintente kunye nokungapheleli kwiinqwelo ziza kuthotywa ngokuqinisekileyo. Ngokufanayo, umdlalo wegeyimu owenziwe ngezinto ezininzi uya kufuna imephu ecacileyo ukuhambisa amanqanaba ahlukeneyo enkqantosi phakathi kwesikhumba somntu, intsimbi yentsimbi kunye nezinto zokugqoka.
I-Bump, Displacement, okanye Imephu eqhelekileyo
Ingqungquthela engaphezulu kunokuba yeyiphi imimiselo emibini yangaphambili, iimephu zeemephu zihlobo lweemephu zemiqondiso ezinganceda ukunika ubungqina obuninzi bokugqithisa okanye ukuchithwa kumgangatho womzekelo.
Cinga udonga lwezitena: Umfanekiso wodonga lwezitena ungaphakanyiswa kwiplanethi yipoloni yiplani kwaye ibizwa ngokuba iphelile, kodwa amathuba akunakubukeka ekholisekileyo ekunikweni kokugqibela. Oku kungenxa yokuba iplani edibeneyo ayiphenduli ngokukhanya ngokufanayo ngendlela yokwakhiwa kwezitena, kunye nokuqhekeka kwayo.
Ukwandisa impembelelo yento yokwenene, i-bump okanye ibalazwe eliqhelekileyo liya kwongezwa ngokuchanekileyo ngokuphindaphindiweyo kwendawo yokuqhafaza yezitena, kwaye kuphakame ukukholelwa ukuba iintlukwano phakathi kwezitena zihlala zihlala endaweni. Ngokuqinisekileyo, kuya kukwazi ukuphumeza umphumo ofanayo ngokufaka imodeli nganye ngesitoreji ngesandla, kodwa inqwelo eqhelekileyo imephu iphezulu kakhulu. Akunakwenzeka ukugqitha ukubaluleka kweemephu eziqhelekileyo kwimidlalo yamanqaku-mdlalo-imidlalo ayikwazanga ukujonga indlela abayenza ngayo namhlanje ngaphandle kweemephu eziqhelekileyo.
Ukuqhuma, ukufuduka, kunye neemephu eziqhelekileyo zixubusha ngokwabo kwaye zibaluleke kakhulu ekufezekiseni ubuchule bezithombe ekunikeni.
Qaphela ukuba inqaku libafake ngokubanzi.
Enye Imephu Iintlobo zokwazi
Ngaphandle kwezi ntlobo ezintathu zemephu, kukho enye okanye ezimbini oza kuzibona ngokuqhelekileyo:
- Imephu yokucamngca : Ixelela isofthiwe leyo iindawo ezithile ze-3D model kufuneka zibonakalise. Ukuba yonke indawo yomzekelo ibonakalisa, okanye ukuba izinga lokubonakalisa lifana nebalazwe imbonakalo ikhutshwe. Iimephu zengcamango zizithombe ze-grayscale, ezimnyama zibonisa u-0% ukubonakalisa kunye nomhlophe ococekileyo obonisa indawo ebonakalayo ye-100%.
- Ibalaphu yokungabonakaliyo: Ngokuchanekileyo njengemephu yokubonakalisa, ngaphandle kokuba ixelela isofthiwe apho iincandelo zeemodeli zimele zibonakalise. Ukusetyenziswa okuqhelekileyo kwimephu yembala kuya kuba yinto ebunzima kakhulu, okanye ixabiso elikhulu kakhulu lokuphindaphindiweyo, njengefowuni yekhonkco. Ukusebenzisa ukukhanya, kunokuba ulandelelwano lweekhonkco ngabanye kunokuqiniseka ngokude nje ukuba umzekelo awubonakali kakhulu kufuphi, kwaye usebenzisa ama-polygons ambalwa.
Sijonge ukudala nokubeka ii-UVs kwaye sihamba kwiindidi ezahlukeneyo zeemephu ezingasetyenziswa kwi-3D model. Uhamba kakuhle endleleni yakho yokuhlaziya imodeli yakho ye-3D!
