La i-retopology bubuchule bedijithali obusekwe kulawulo kunye nokwenza lula amanani e-3D. Ngokusisiseko iqulathe ukulandelela okanye ukuzoba ngokutsha umzobo osele ukhona ngokusebenzisa iipoligoni, ukunciphisa kakhulu iipoligoni zoqobo inokuba nalo mfanekiso ekuqaleni.
I-Retopology yinkqubo ebalulekileyo ngaphakathi Itekhnoloji ye-3d, kuba ivumela ukunyusa ijometri yeemodeli, ukuphucula umgangatho wabo wokubonwayo kunye nokuququzelela i-animation yabo. Kweli nqaku siyacacisa yintoni i-3D retopology kwaye yeyantoni.
Yintoni i-topology yemodeli ye-3D
Ukuqonda ukuba yintoni i-retopology, kufuneka uqale wazi ukuba yintoni i-topology yemodeli ye-3D. I-Topology ibhekisa kwindlela apho iipolygons ezenza umphezulu wemodeli zisasazwa kwaye ziqhagamshelwe. Iipolygons zinokuba ziindidi ezintathu:
- oonxantathu okanye oonxantathu: ziipoligoni ezinamacala amathathu. Zezona zilula kwaye zezona zikhubaza imodeli kancinane, kodwa kunye nezo zivelisa owona mthwalo wepolygonal.
- Iiquads okanye izikwere: ziipoligoni ezinamacala amane. Zizona zinconywa kakhulu kwiimodeli ezininzi, njengoko zikuvumela ukuba uhlukanise kwaye ululaze ngaphandle kokuphazamisa ukuhamba kwejometri.
- Ii-N okanye iipolygons ezinamacala angaphezu kwamane: zizipoligoni ezinamacala amahlanu nangaphezulu. Zezona ziyingxaki, njengoko zibangela izinto ezibonwayo kwaye zenze oopopayi babe nzima.
Ukongeza kwiipolygons, kukho ezinye izinto ezenza i-topology yemodeli ye-3D:
- loop: luluhlu lwemida (edge loop) okanye iipoligoni (ikhonkco lobuso) idityaniswe, icwangciswe njengeringi. Iiluphu zilandela iimilo zemodeli kwaye zichaze isakhiwo sayo.
- I-Pole: yi-vertex apho kuhlangana khona imiphetho emihlanu nangaphezulu. Izibonda zinokubangela ukuguquka okungaqhelekanga xa ku-animated, ngoko zama ukuzibeka kwiindawo ezikhululekile zemodeli.
Ziziphi iintlobo ze-retopology ezikhoyo
I-retopology ezenzekelayo yinto eyenziwa yi-3D yesoftware yomfuziselo ngokwayo, ihlalutya i-mesh kunye nokubeka ngokutsha iipolygons ngendlela ebona ukuba isebenza kakhulu. Olu hlobo lwe-retopology lunciphisa kakhulu inani lobuso, kodwa aluvelisi ijometri ecocekileyo, ngoko ke ukusetyenziswa kwayo kunqatshelwe xa kusenziwa i-rigs okanye i-animations. Nangona kunjalo, isantya sesixhobo senza ukuba kube lula ukwenza lula izinto ezingaphiliyo ngokucofa kanye.
La retopology ngesandla Yinto eyenziwa ligcisa le-3D, libala imodeli ye-3D ibeka i-vertex nganye ngokuchanekileyo kunye nobuchule. Olu hlobo lwe-retopology luvelisa ijometri ephuculwe ngakumbi elungelelaniswe kwimodeli, yiyo loo nto ibalulekile kwiimodeli eziya kwenziwa zibe oopopayi. Oku kulandelayo kuthathelwa ingqalelo kwinkqubo:
- EImodeli kufuneka yenziwe ikakhulu ngeequads. Oonxantathu banokuvunyelwa kwiindawo ezifihlakeleyo kakhulu njengendlebe okanye umlomo. Ii-n-gons azivumelekanga kuyo nayiphi na imeko.
- Iilophu zilandela iimilo zemodeli kangangoko kunokwenzeka. Ngokomzekelo, imilebe okanye amashiya sele echazwe ngokucwangciswa kwemida.
- Izibonda zibekwe kwiindawo ezikhululekile zemodeli, apho zingachaphazeli i-deformation.
Isoftware yemodeli nganye ijongana nenkqubo yohlengahlengiso ngendlela eyahlukileyo kancinane. Kukho nezo zidalwe ngokukodwa lo msebenzi, njengeTopoGun okanye i-3D-Coat.
Zeziphi iingenelo zokwenza iretopology elungileyo?
Ukwenza i-retopology elungileyo kuneengenelo ezininzi, zombini zobugcisa kunye nobugcisa. Ezinye zazo zezi:
- UkuNcitshiswa koMthwalo wokuThamba: Ngokwenza lula ijometri yomzekelo, inani leepolygons liyancitshiswa, kwaye ngoko ke ubunzima befayile kunye nokusetyenziswa kobutyebi besofthiwe ye-animation okanye injini yomdlalo.
- Ukuphuculwa komgangatho wokubonwayo: Xa usebenzisa i-quads, unokwahlula into eninzi njengoko ufuna ngaphandle kokutshintsha ukuhamba kwee-loops, kukuvumela ukuba ululaze umnatha kwaye usebenzise iimephu eziqhelekileyo kunye nokunyaniseka okuphezulu.
- ukuququzelela oopopayi: Ngokuba nejiyometri ecocekileyo nelungeleleneyo, izinto zakudala kunye nezigoso ezingaqhelekanga ziyaphetshwa xa kukhubaza imodeli. Ukongeza, unokwenza i-rig echanekileyo ngakumbi kunye nokulawula okungcono ubunzima beempembelelo.
Kulungile, ndidale icandelo elinye kwaye ndahlulahlula laba yimihlathi emine. Ndikrwelele awona magama abalulekileyo abhalwe ngqindilili. Apha unesiphumo:
Indlela yokwenza i-retopology elungileyo
Ukwenza i-retopology elungileyo akuyona into elula, kuba kufuna umonde, ukuchaneka kunye nolwazi oluninzi. Nangona kunjalo, kukho iingcebiso ezinokukunceda uphucule ubuchule bakho kwaye ufumane iziphumo ezingcono. Nazi ezinye zazo:
- Funda i-anatomy yemodeli: Ngaphambi kokuba uqale ukuphindaphinda, kubalulekile ukuba uhlalutye imilo kunye nokuhamba kwemodeli oza kuyilandela. Ngale ndlela uya kukwazi ukuchonga ezona ndawo zibalulekileyo, izihlunu, amalunga kunye neefolthi omele uzihloniphe ngeelophu.
- sebenzisa iimbekiselo: ungazami ukwenza i-retopology kwimemori okanye ngeso. Jonga iireferensi ezivela kwamanye amagcisa e-3D ayenze i-retopology efana neyakho kwaye ubone indlela abasasaze ngayo iipolygons, iilophu kunye neepali. Unokufumana iireferensi ezininzi kwi-intanethi, ezinje ngale PDF enamacebiso angama-50 e-retopology.
- landela ulandelelwano olusengqiqweni: ungaqalisi ukucela uxolo kuyo nayiphi na indawo yomzekelo. Kungcono ukuqala ngezona ndawo zilula kwaye usebenze indlela yakho ukuya kwezona zinzima kakhulu. Ngokomzekelo, unokuqala nge-torso kwaye usebenze indlela yakho ukuya kwiingalo, imilenze, intloko kunye nezandla. Ngale ndlela uya kukuphepha ukwenza iinxalenye zomsebenzi okanye ushiye izikhewu ngaphandle kokuzalisa.
- Sebenzisa izixhobo ezifanelekileyo: isoftware nganye yomfuziselo inezixhobo zayo zokwenza iretopology, kodwa ayizizo zonke ezisebenza ngokulinganayo okanye zikhululekile. Kuyafaneleka ukuba ukhethe isoftware elungele iimfuno zakho kunye nezinto ozikhethayo, kwaye ufunde ukusebenzisa imisebenzi yayo ethile kwi-retopology. Isoftware esetyenziswa ngokubanzi kule njongo yiBlender, iMaya, iZBrush, iTopoGun okanye i3D-Coat.
ukuzonwabisa engqondweni yakho
Omnye unokuthi i-retopology yi ubuchule bedijithali ebandakanya ukwakhiwa ngokutsha komphezulu wemodeli ye-3D kunye nejometri ephuculwe ngakumbi. Kukho iindidi ezimbini ze-retopology: i-automatic kunye ne-manual. I-automatic iyakhawuleza kodwa ayichanekanga, ngelixa i-retopology yenziwa kancinci kodwa ichanekile kakhulu. Yenza iretopology elungileyo Ineengenelo ezininzi ke ngoku uyazi ukuba ungayisebenzisa njani le nto kuncedo lwakho
Ndiyathemba ukuba ulithandile inqaku kwaye likuncedile ukuba ufunde ngakumbi malunga nehlabathi le-retopology. Ukuba unayo nayiphi na imibuzo okanye iingcebiso, zive ukhululekile ukuphawula. Masikhe kwakhona!
