Ukukhanyisa i-3D Scene. Izandi ezilula zilula & # 39;
Ngokona nxalenye, ukukhanya "kwihlabathi lenene" kubonakala nje kwenzeka. Ilanga likhuphuka, sitshintshela umtshini, okanye sivula iziphofu kunye ne-voila, ukukhanya! Singafaka ingcamango apho sibeka khona isibane, indlela esilungisa ngayo iimpumputhe, okanye apho sijonge khona i-flashlight, kodwa iipesenti ezingamashumi asibhozo kwexesha lethu ngamava alungelelwanga.
Izinto zihluke kwishishini lemifanekiso yekhompyutha.
Njengoko naliphi na umfaki-mfanekiso omkhulu onokukuxelela, ukukhanyisa yinto yonke.
Kulungile, yonke into ingaba yi-hyperbolic, kodwa ukuba nesisombululo sokukhanyisa kakuhle singenza okanye siphume. Ngaphandle kokukhanyisa okukhulu, imodeli engummangaliso ye-3D ingagqiba ukukhangela i-flat and unconcting in the image.
Andiyi kuchitha ixesha elininzi kukukhawuleza ngezizathu zokuba ukukhanyisa kubaluleke kakhulu (kunye nangaphantsi kwexabiso) kwipayipi yeCG .
Kodwa yenza iphepha lixhamle, kwaye siza kuqalisa ingxoxo yethu yeendlela zokukhanyisa ze-3D ngokugqithisileyo kweentlobo ezintandathu zezibane ezifumaneka kwiiphakheji eziqhelekileyo ze-3D.
Nangona kulula kakhulu ukuchofoza "ukudala ukukhanya," iqhosha kwi- software yakho yepakethe ye-3D uze ubeke umthombo wokukhanya kwimeko yakho, into eyenziwa yile mveliso iyinkimbinkimbi kakhulu.
Kukho inani leepaldidi ezikhanyisiweyo ze-3D, kwaye uhlobo lwesimo ngokuqhelekileyo lubonisa ukuba yiyiphi enye efanelekileyo. Ngokomzekelo, izakhono ezisebenza kakuhle kwindawo yangaphakathi zihlala ziyenza ingqiqo encinci kwiphefumla yangaphandle. Ngokufanayo, i-studio "ukukhanyisa ukuveliswa kwemveliso okanye impawu idinga inkqubo eyahlukileyo kakhulu ekukhanyeni iifoto kunye nefilimu.
Ekugqibeleni, yonke imeko ihlukile, kodwa iintlobo ezithile zokukhanya zisebenza kakuhle kwiindawo ezithile.
Nazi ezinye zeendlela zokukhanyisa eziqhelekileyo ezifumaneka kwii- software ezininzi ze-software ze-3D :
- Ukukhanya / Ukukhanya kwe-Omni: Ukukhanya kwesikhombiso kubangela ukukhanyisa ngaphandle kwinqanaba ngalinye ukusuka kwinqanaba elincinci elingenanto kwi- 3D space . Izibane zepalati zinceda ukufanisa naluphi na umthombo wokukhanya omnidirectional: Ama-bulb, ikhandlela, izibane zomthi Krisimesi, njl njl.
- Ukukhanya okuLawulayo: Ngokungafani nezibane zendawo, ezihlala kwindawo ethile kwindawo yesimo se-3D, ukukhanya okukhokelo kuthetha ukumela umthombo wokukhanya ode kakhulu (njengelanga okanye inyanga). Iirhasi ezikhutshwa kwizibane ezikhokelo zihamba ngokuhambelana kwindlela enye ukusuka esibhakabhakeni, kwaye zisetyenziselwa ukulinganisa ilanga ngqo. Ngenxa yokuba ukukhanya okubhekiselele kubonisa umthombo wokukhanya okude, i-x, y, z i-coordination ayithethi nto-kuphela kuphela impawu zayo zokujikeleza zinalo naluphi na ukuchaphazeleka kwindlela esiza kukhanya ngayo.
- I-Spot Light: Izibane zesikhokelo kwi-3D izicelo zizichaza ngokucacileyo ngenxa yokuba zifana neendawo zabo zangempela-hlabathi. Ukukhanya okubonakalayo kukhupha intsimi ekhanyisiweyo yenkalo ukusuka kwindawo enye kwindawo. Iziflethi zihlala zisetyenziselwa ukukhanya kwee- studio ezintathu zendawo, kunye nokufanisa nayiphi na indawo yokukhanya apho kukho indawo ebonakalayo ebonakalayo ukusuka ekukhanyeni ukuya kumathambeka-mnyama, izibane zedesi, ukukhanya kwekhoni, kunye nokunye.
- Ummandla wokuKhanya: Ukukhanya kwendawo kukukhanya okusekelwe emzimbeni okwenza imida eqondayo ivela ngaphakathi kwimida emiselweyo. Izibane zendawo zinomfanekiso othize (okanye ixande okanye iisetyhula) kunye nobukhulu, okwenza kube luncedo kakhulu ukufanisa izinto zokukhanya zeplanti, ii-panels ezikhanyayo kunye nezinye izinto zokukhanya ezifanayo. Izibane zendawo zingasetyenziselwa ukuphuma kwi-photon xa zisetyenziselwa ukukhanya komhlaba jikelele kwi-Ray mental, eyenza ukuba zikhethwe ngokubanzi ekukhanyeni kwemveliso kunye nokubonwa kwezakhiwo. Nangona izibane zendawo zikhokelo jikelele, azikhiphi imisebe efana neyokukhanya.
- Umbane woMbane: Ukukhanya okuvakalayo mhlawumbi kuyona nto inzima kunazo zonke ukumbamba intloko. Ngezicwangciso ezingagqibekanga, ziphantse zifana nokukhanya kwebala, ukuphuma kwemida ye-omnidirectional ukusuka kwindawo ephambili. Nangona kunjalo, ngokungafani nokukhanya kwendawo, ukukhanya okubonakalayo kunomfanekiso othile kunye nobukhulu, bobabini obuchaphazela iphethini yayo. Ukukhanya okubonakalayo kunokubekwa kwimeko yeyiphi i-geometric primitive (cube, sphere, cylinder, njl.), Kwaye ukukhanya kwayo kuya kukhanya kuphela kwimiqulu ngaphakathi kwaloo mqulu.
- Ukukhanya okumangalisayo: Ukukhanya okukrakra kubangela ukukhanya okukhanyayo kummandla wonke, kwaye kungasetyenziselwa ukuphakamisa izinga elipheleleyo lokukhanyisa kwimibala. Ayinazo izikhokelo ezicacileyo, ngoko ke akayi kuthungatha isithunzi somhlaba, nangona kungenjalo i-omnidirectional efana nokukhanya kwendawo. Ukukhanya okuqhelekileyo kufana nokukhanya okuye kwavela kusihlwa, emva nje kokuba ilanga libekwe.
Iintlobo zokukhanya esizixubushe apha zingasetyenziselwa nantoni na kwi-studio ebonakalayo yokukhanyisa i-studio ukufikelela kwiimpawu eziyinkimbinkimbi ezifuna izibane ezingama-40+. Bahlala besetyenziselwa ngokubambisana omnye nomnye-kunqabile kakhulu ukuba indawo iya kubandakanya izibane, okanye zibandakanya izibane zendawo, njl.
Nangona kunjalo, sithatha nje ukuqala ukukhangela umxholo wesihloko esicacileyo kunye ehlukahlukeneyo. Siza kushicilela i-athimba "ekuphambili" kwe-3D ukukhanya ngethuba elithile kwiveki ezayo, apho esiza kuzisa khona i-HDRI, ukunyuswa kwamagama kunye nokukhanya kwehlabathi jikelele.
Okwangoku, zizinto ezimbalwa zezinto zangaphandle ekukhanyeni kwe-3D:
