Ukukhanyisa i-3D Scene. Umsindo omuhle kakhulu awunakho & # 39; t?
Ngokuyinhloko, ukukhanyisa "ezweni langempela" kuvame ukwenza nje. Ilanga liphuma, sibheka inkinobho, noma sivula izimpumputhe kanye ne-voila, ukukhanya! Singase sicabange ukuthi sibeka kuphi isibani, indlela esizibheka ngayo izimpumputhe, noma lapho sihlose khona i-flashlight, kodwa amaphesenti ayisishiyagalolunye esikhathi esikuhlangenwe nakho kwethu ngokukhanya akufanelekile.
Izinto zihlukile embonini yegraphic computer.
Njengoba noma iyiphi i-photographer enhle engakutshela, ukukhanyisa kuyinto yonke.
Kulungile, konke kungase kube yi-hyperbolic, kodwa ukuba nesisombululo sokukhanyisa kahle singenza noma siphume kakhulu. Ngaphandle kokukhanyisa okukhulu, ngisho nemodeli enhle ye- 3D ingaqeda ukubuka flat nokungaqiniseki esithombeni sokugcina.
Ngeke ngichithe isikhathi esiningi kakhulu ngikugxeke ngezizathu zokuthi ukukhanyisa kuyisici esibalulekile (futhi esingathandwa kakhulu) sephayiphi ye- CG .
Kodwa yenza ikhasi lifinyelele, futhi sizoqala ingxoxo yethu yamasu okukhanyisa e-3D ngokubukezwa kwezinhlobo eziyisithupha zezibani ezitholakala kumaphakheji we-software ejwayelekile e-3D.
Yize kungcono kakhulu ukuchofoza inkinobho ethi "ukudala," inkinobho yakho ye-software ye-3D bese ubeka umthombo okhanyayo endaweni yakho, iqiniso lekhono liyinkimbinkimbi kakhulu.
Kunezinombolo eziningi zama-paradigms ezikhanyiswa kahle ze-3D, futhi uhlobo lwesimo ngokuvamile kuvumela ukuthi iyiphi efanele kakhulu. Isibonelo, amasu asebenza kahle emvelweni wangaphakathi ngokuvamile enza umqondo omncane kakhulu ngokudubula kwangaphandle. Ngokufanayo, ukukhanyisa "studio" yokukhishwa komkhiqizo noma uhlamvu kudinga inqubo ehluke kakhulu ekukhanyiseni izithombe namafilimu.
Ekugcineni, zonke izimo zihlukile, kodwa izinhlobo ezithile zokukhanya zisebenza kahle ngezigcawu ezithile.
Nazi ezinye zezinketho zokukhanyisa ezijwayelekile ezitholakala kuma- software amaningi e- software e- 3D :
- Ukukhanya / ukukhanya kwe-Omni: Ukukhanya kwephuzu kubangela ukukhanyisa kwangaphandle kuzo zonke izindawo ukusuka endaweni eyodwa, engapheli emkhathini we-3D . Izibani zokuphawula ziwusizo ekufaniseni noma yikuphi umthombo wokukhanya omnidirectional: Ama-Light, amakhandlela, izibani zezihlahla zikaKhisimusi, njll.
- Ukukhanya okuqondisayo : Ngokungafani nezibani zokukhomba, ezihlala endaweni ethile endaweni yesimo se-3D, ukukhanya okuqondisayo kusho ukumela umthombo wokukhanya ode kakhulu (njengelanga noma inyanga). Ama-Rays aphuma ezikhanyeni eziqondiswayo ahamba ngendlela efanayo ukusuka kunoma iyiphi indawo esezulwini, futhi ngokuvamile asetshenziselwa ukulingisa ilanga eliqondile. Ngenxa yokuthi ukukhanya okuqondisayo kubonisa umthombo wokukhanya ode kakhulu, i-x, y, z, i-coordination yayo ayisho lutho-kuphela ukuthi imfanelo yayo yokujikeleza inomthelela wokuthi isimo sizokhanya kanjani.
- I-Spot Light: Izibani ze-Spot kuzinhlelo zokusebenza ze-3D ziyizizathu ezicacile ngenxa yokuthi zifana nezihlobo zabo zangempela. Ukukhanya okukhanyayo kuveza insimu yokukhanya efana nesibhakabhaka kusuka endaweni eyodwa endaweni. Ama-spotlights ngokuvamile asetshenziselwa ukukhanya kwe-studio ye -point-point, futhi nokufanisa noma yikuphi ukukhanya okukhanyayo lapho kunemibono ebonakalayo ebonakalayo kusukela ekukhanyeni kuya emgwaqweni omnyama, izibani zedesksi, ukukhanyisa okunamandla kogu, njll.
- Indawo Yokukhanya: Ukukhanya kwendawo kungukukhanya okusekelwe ngokomzimba okuvula imilayezo eqondisayo ukusuka ngaphakathi kwemingcele ebekiwe. Izibani zendawo zinejamo elithile (eliyi-machungechunge noma eliyingqayizivele) nosayizi, okwenza kube usizo kakhulu ekufaniseni izinto zokukhanya ezikhanyayo, amaphaneli abuyiselwe emuva, nezinye izici ezifanayo zokukhanyisa. Izibani zendawo zingasetshenziswa njengama-photon emitters lapho zisebenzisa ukukhanya komhlaba jikelele kuMental Ray, okwenza kube yinto ethandwayo ekukhanyeni komkhiqizo nokubukwa kwezakhiwo. Nakuba izibani zendawo zineziqondiso ezijwayelekile, azikhiphi imisebe efana nokukhanya.
- Umbhalo Wokukhanya: Ukukhanya okuvuthayo mhlawumbe kuyinkimbinkimbi yokumboza ikhanda lakho nxazonke. Ngezilungiselelo ezizenzakalelayo, cishe kufana nokukhanya kwephuzu, ukukhipha imisebe yama-omnidirectional kusuka endaweni ephakathi. Kodwa ngokungafani nokukhanya kwephuzu, ukukhanya kwe-volumetric kunesimo esithile nesayizi, okubili kokuthinta iphethini yayo yokuthutha. Ukukhanya okunamandla kungasethwa ekujuleni kwanoma iyiphi i-geometric primitive (cube, sphere, cylinder, njll), futhi ukukhanya kwayo kuzokhanyisa kuphela izindawo ngaphakathi kwalelo volumu.
- Ukukhanya Okumangalisayo: Ukukhanya okumnyama kuveza ukukhanya okukhanyayo kunoma iyiphi indlela, futhi kungasetshenziselwa ukuphakamisa izinga lonke lokukhanyisa okusabalalisa endaweni yesehlakalo. Ayikho isiqondiso esithile, ngakho-ke asikho isithunzi somhlabathi, kodwa akusiwo omnidirectional ngempela njengokukhanya kokukhomba. Ukukhanya okuncane kufana nokukhanya okwenzeka kusihlwa, ngemuva nje kokushona kwelanga.
Izinhlobo zokukhanya esizixoxile lapha zingasetshenziswa kunoma yikuphi ukukhanya kwe-studio ekhomba ngamaphuzu kuya ezigciniwe eziyinkimbinkimbi ezidinga izibani ezingu-40 +. Sezohlale zisetshenziswa ngokubambisana-kungavamile kakhulu ukuthi isenzakalo sizofaka kuphela izibani zendawo, noma zifaka kuphela izibani zendawo, njll.
Noma kunjalo, sesisanda kuqalisa ukuqala ubuso besifundo esijulile nesihlukahlukene. Sizoshicilela i-athikili ekukhanyeni kwe-3D "okuthuthukisiwe" ngesinye isikhathi ngesonto elizayo, lapho sizofaka khona i-HDRI, ukuvelela okufakiwe, nokukhanyisa umhlaba wonke.
Okwamanje, nansi izinsiza ezimbalwa zangaphandle ekukhanyeni kwe-3D:
Umbala nokukhanya - uJames Gurney (Umbono, ukuphakanyiswa kakhulu)
I-Lighting La Ruelle (Isifundo sokukhanyisa ngaphandle)
I-Lighting La Salle (Isifundo sokukhanyisa ngaphakathi)
