- Umdwebi wezithombe uguqula izinhlelo zokwakha zobuchwepheshe zibe yizithombe ze-3D ezingokoqobo esebenzisa isofthiwe ekhethekile.
- Le ndima idinga inhlanganisela yobuchwepheshe bokwenza amamodeli nokukhanyisa kuhlanganiswe nolwazi lobuciko lokuthatha izithombe nokuklama kwangaphakathi.
- Imisebenzi yobungcweti ihilela ukulandelana okuqinile kusukela ekudalweni kwejiyometri yokuqala kuya ekukhiqizweni kokugcina ukuze kube nomthelela omkhulu.
Wake wazibuza ukuthi lezo zithombe ezimangalisayo zezakhiwo ezingakakhiwa zakhiwa kanjani? Lokho kungumlingo womculi wokudweba , noma "i-renderista," osebenza. Laba ochwepheshe basebenza njengebhuloho phakathi kohlelo lobuchwepheshe nephupho elibonakalayo, beguqula imigqa ebandayo kanye nezilinganiso zibe yizindawo ezijulile ezizwakala ziphila futhi zibambeka.
Kungakhathaliseki ukuthi basebenza enkampanini yokwakha izakhiwo ezincane noma njengabazimele, laba baculi abagcini nje “ngokuchofoza izinkinobho” kukhompyutha. Bahlanganisa ubunjiniyela bezobuchwepheshe neso lobuciko elibukhali ukusiza amakhasimende, abatshalizimali, kanye nabanini bezindlu ukuba babone amandla aphelele ephrojekthi isikhathi eside ngaphambi kokuba kubekwe isitini sokuqala. Yindima edinga amakhono ahlukene , kusukela ekuqapheliseni indawo kuya ekuqondeni okujulile ukuthi ukukhanya kuhlangana kanjani nezindawo ezahlukene.
Indima Eyinhloko Yomculi Odwebayo
Ezindaweni eziningi zokwakha, umdwebi wokudweba ungumuntu okhethwayo wokukhiqiza izithombe ezicatshangwayo. Umsebenzi wabo oyinhloko ukwenza imodeli yephrojekthi kusukela ekuqaleni , ukusebenzisa ukwakheka, ukusetha isimo ngokukhanya, nokukhiqiza isithombe sokugcina esinesinqumo esiphezulu. Nakuba abaningi bengabafundi bezokwakha noma abaphothule, awudingi ngempela iziqu zokuklama ukuze uphumelele. Noma ubani oqonda kahle amapulani okwakha futhi oqonda izilinganiso zendawo angachuma kulo mkhakha.
Yiqiniso, uma umculi engeyena umakhi wezakhiwo, angase abe nenkinga encane ngamagama athile embonini ekuqaleni, kodwa lokho kuyinto evame ukucaca ngolwazi oluthile. Ngokuthakazelisayo, le ndlela yomsebenzi ivulekele isixuku esihlukahlukene, okuhlanganisa abaklami bezithombe, onjiniyela bezakhiwo, kanye nabaklami bangaphakathi , bonke abaletha ukunambitheka okuhlukile emphumeleni wokugcina.
Ulwazi Olubalulekile kanye namaSethi Amakhono
Ukuba uchwepheshe akukhona nje ukwazi ukuthi iyiphi isofthiwe okufanele uyisebenzise; kumayelana nokuqonda isayensi yobuhle . Umculi osezingeni eliphezulu udinga ukwazi kahle ngemibono yombala, izithombe, kanye nokuklama kwangaphakathi . Kungani? Ngoba umdwebo we-photorealistic awukona nje ukubeka usofa ekamelweni; kumayelana nokwazi ukuthi izingcezu zefenisha zikhula kanjani nokuthi izinto ezahlukene zibonisa kanjani ukukhanya ezweni langempela.
Ngaphandle kohlangothi lobuciko, kunesidingo esikhulu sobuchwepheshe: ikhono lokufunda amapulani . Lokhu akunakuxoxiswana ngakho. Ngaphandle kokukwazi ukuhumusha amapulani, umdwebi akakwazi ukwenza amamodeli ezinto ngokunembile, ukuqonda ukuthi izibani ziya kuphi, noma ukubeka ifenisha ngokombono womklami. Kwamanye amahhovisi, anikwe ngisho nomsebenzi wokuphakamisa ukwakheka nezinto zokuhlobisa , yingakho ukuba nesizinda sokuklama kuyinzuzo enkulu yokugwema ukuphazamiseka emsebenzini.
Ukuhamba Komsebenzi Wobuchwepheshe: Kusukela Kumqondo Kuya Esithombeni Sokugcina
Ukudala i-render ephezulu kuwumjaho we-marathon, hhayi ukushesha. Ukuze ugweme labo bantu abasatshwayo ubusuku bonke, uchwepheshe kumele aphathe isikhathi sakhe ngokucophelela futhi aqonde ukuthi yini edingekayo. Inqubo ngokuvamile ilandela lezi zinyathelo:
- Ukumodela kwe-3D: Lesi yisisekelo. Ukusebenzisa amathuluzi anjenge I-Blender, i-3ds Max, noma i-Cinema 4D, umdwebi wakha i-geometry. Uma izilinganiso zingalungile lapha, akukho ukukhanya okuhle okuzosindisa iphrojekthi.
- Ukuthunga kanye nezinto zokwakha: Yilapho isithombe sithola khona "umuzwa" waso. Ngokusebenzisa isofthiwe efana Umdwebi Wezinto, umdwebi uchaza ukuthi indawo iwubucwebe bensimbi, imabula epholishiwe, noma indwangu ethambile.
- Ukukhanyisa: Mhlawumbe isinyathelo esibaluleke kakhulu. Ngokusebenzisa Amamephu e-HDRI noma izibani zokwenziwa, umdwebi udala isimo. Ukukhanyisa kutshela umbukeli ukuthi usuku lwemvula olunesimo sezulu noma ekuseni okukhanyayo kwehlobo.
- Ukusethwa Kwekhamera: Njengasezithombeni zangempela, ubude bokugxila kanye ne-engeli kungenza noma kuphule ukwakheka.
- Inqubo Yokuphrinta: Ikhompyutha ibala ukukhanya okukhanyayo kanye nokukhanyaKuye ngokuthi lokhu kuyinkimbinkimbi kangakanani, kungathatha amahora noma izinsuku, okuvame ukudinga amapulazi okunikeza yokuphakamisa okusindayo.
- Ngemuva Kokukhiqiza: Ukukhishwa okuluhlaza akuvamile ukuba umkhiqizo wokugcina. I-Photoshop noma i-After Effects, umdwebi ulungisa imibala futhi alungise ukungapheleli ukuze ayinike leso sici sokugcina "sokumangaza".
Amaqiniso eSoftware kanye neBhizinisi
Uma kukhulunywa ngamathuluzi, imboni isebenzisa izinjini ezahlukahlukene njenge -V-Ray, i-Lumion, noma i-Octane , kuye ngokuthi zidinga isivinini esingakalungwanga noma ubuqiniso obuphelele. Into ebaluleke kakhulu ukuthi iningi lesofthiwe ye-3D liyahambisana ; isibonelo, i-3ds Max ingangenisa amafayela kusuka ku-Archicad , Revit, noma i-SketchUp kalula.
Ngokombono webhizinisi, amanani awavami ukuncika enanini lezithombe, kodwa esikhathini esichithwa ukusetha indawo . Ukwakha indawo ezungezile yingxenye enzima kakhulu; uma indawo isilungile, ukukhiqiza ama-engeli engeziwe kuyashesha. Iphutha elivamile elenziwa amakhasimende ukukhawulela isikhathi esifushane kakhulu noma ukucela i-engeli eyodwa ukuze wonge imali, bengaqapheli ukuthi iningi lezindleko lisekuhlanganisweni kwendawo yokuqala.
Umgomo oyinhloko womculi odwebayo ukudala isithombe esingajabulisi nje kuphela umakhi, kodwa empeleni sithengisela umthengi wokugcina umbono . Ngokuhlanganisa ukunemba kobuchwepheshe nokuqonda imizwa yomuntu nokukhanya, laba baculi baguqula imidwebo eyisicaba ibe amaqiniso edijithali athakazelisayo achaza ikusasa lesikhala.
Unjiniyela. I-Tech, isofthiwe nesithandi sehadiwe kanye ne-tech blogger kusukela ngo-2012
