Iifayile zekhompyutha ze-3D, iFilimu, kunye nayo yonke i-Z-Axis ebalulekileyo
Ukuqwalasela imifanekiso yekhompyutha ye-3D okokuqala, nokuba unomdla kwifilimu ye-3D, imbonakalo ye-3D, okanye umveliso wez animation kunye / okanye imidlalo yevidiyo? Oku kungeniswa ngokubanzi kwi-3D, ngoko siya kuchaza eli gama ngokubanzi, uchaza indlela ehambelana ngayo nemithombo kunye namanqaku apha kule ndawo, kwaye ikunike ingcamango yokuba ufuna inkcazelo engakumbi.
Ngoko, Yintoni i-3D?
Ngenkcazo ebanzi yekota, i-3D iya kuchaza nayiphi na into eyenzeka kwi-systemesi ye-Cartesian system coordinate system. Ukuba oko kuyandila ubuchwephesha bobuchwephesha, ungesabi - siya kusisusa ngokukhawuleza.
I-Cartesian system coordinate is indlela ekhethekileyo yokuchaza i-X ne-Y axxes sonke siqhelana ne-geometry ephakamileyo (cinga iphepha legrafu).
Uyakhumbula ukwenza ii-grafu ezincinci kunye ne-X axis ehamba phambili, kwaye i-Y axis iyinto ecacileyo, kunjalo? Izinto zifana kakhulu kwihlabathi le-3D, ngaphandle kweyodwa - kukho i-axis yesithathu: Z, emele ubunzulu .
Ngaloo nkcazo, nayiphi into enokumelwa kwiinkqubo ezintathu ze-axis yi-3D. Akuyona ibali lonke, kunjalo.
I-3D ngokumalunga nezobuGcisa
Ngaba unokufunda oku ngenxa yokuba unomdla ogqithisayo kwi-3D njengoko ubhekiswa kuyo kwikhompyutheni yecomputer , equka ifilimu, ithelevishini, ukukhangisa, ubunjineli, kunye nophuhliso lwezemidlalo.
Iingongoma ezimbalwa eziphambili kwiifayile zekhompyutha ze-3D:
- Ingcaciso ebalulekileyo ye-3D space igcina enye: Yonke into malunga ne-X, Y, kunye ne-Z-axis inokwenene, kodwa kukho enye ibambe. Ngelixa izinto zangempela zehlabathi ze-3D zikhona ngokwenqanaba elinesithathu, kwilizwe ledijithali yeempawu zekhompyutheni ze-3D ziyakwazi ukumelwa kuphela ngokwemathematika .
- Iimodeli ze-3D: Nawuphi na ummeli wento kwisithuba sedijithali, ubizwa ngokuba ngumzekelo we- 3D . Ukuba ukhangele ulwazi oluluhlaza oluqulethe imodeli ye-3D eyimfuneko, ngokukhawuleza (okanye kungabi njalo nje) kuba yiqoqo leenkcukacha zeenkcukacha eziphawula amawaka okanye izigidi zeendlela ezihlukileyo kwi-Cartesian space.
- Isofthiwe yenza izibalo: Ngenhlanhla kubaculi, i-software ye-3D isebenzisana nazo ezininzi zezibalo ezilukhuni. Esikwi-graphical user interface yeprogram ye-3D njenge-Autodesk 3ds Max okanye iMaya , iifom ze-3D zichazwa ngokuzenzekelayo kwaye ziboniswe ngokubonakalayo njengezinto zejometri ezenziwe ngamaphethelo, imizobo kunye ne-polygonal. Uninzi lwezimo zeeprosoft zakha kwii- real-time zinikezela ngeenjini ezikwazi ukubonisa imodeli ye-3D ngokukhanyisa okubonakalayo, izithunzi, kunye nemifanekiso.
Ngaphezu kwe-Z-Axis:
Ekubeni i-Z-axis iyimpawu ezibalulekileyo ze-3D space, masiqwalasele ngokuthe ngqo ukuba yiyiphi "Z" ithetha ngokwenene kwi-software yesimo se-3D. Ukulungelelaniswa kweZ kungasetyenziselwa ukulinganisa izinto ezine kwimifanekiso yekhompyutha ye-3D:
- Ubunzulu bezinto ngokobukhulu. Njengoko, amaqununu ama-5 ububanzi, iiyunithi ezi-4 ubude, kunye neeyunithi ezi-3 ezinzulu .
- Indawo yendawo ephathelene nomvelaphi. Imvelaphi kunoma yimuphi umboniso we-3D (0,0,0) kunye nenani lesithathu lidla ngokuba "Z". Kukho iiphakheji ezimbalwa ze-3D ezisebenzisa i-Z njenge-axis esecaleni, kodwa ezi ziko zincabile.
- Umgama wento ukusuka kwikhamera ekwenziwe, eyaziwa kwimifanekiso yekhompyutheni njengenzulu. I-Z-Depth isoloko isetyenziselwa ukusetyenziswa kwefuthe lemiphumo yenkalo emva kokuveliswa kwemveliso, kwaye kwimidlalo yevidiyo isetyenziselwa ukulungiswa kweenkcukacha.
- I-A-axis of rotation . Umzekelo, ibhola ekhwela kwikhamera iya kuthi ijikeleze kunye ne-Z-axis engalunganga.
I-3D ngokumalunga neFilimu / iCinema:
Igama elithi 3D lithetha into ehluke ngokupheleleyo xa isetyenziswe ekubhekiselele kwiimvumi ze-3D (uhlobo olufuna ukuba ugqibe iiglasi kwaye wenze ukuba ufuna ukufikelela kwaye uzame ukuchukumisa izinto eziphuma kwisikrini). Iifilimu ze-3D zinokuthi, kwaye kaninzi ziyakwenza, zinomxholo wemifanekiso yekhompyutheni ye-3D, nangona kuninzi iifrimu ezingezizo iiCG ezisebenzise ukuhlaziywa kwamuva kwe-3D cinema.
Uphawu olucacileyo lwe "3D" njengoko sicinga ngalo kwi-movie yeshashalazi (kwaye ngoku ekhompyutheni yasekhaya ), kukuba abenzi bamabhayisikobho kufuneka basebenzise ezinye iindlela zokukhohlisa inkqubo yobubonwa babantu ibe ngumbono wobunzulu obunzulu.
- Ukuhlukana kweBinetyana: Isihluthulelo sokujonga ukujongwa kwabantu kunento yonke enokuyenza kunye nokuba amehlo ethu ngamnye athumela umfanekiso ohlukileyo kwiqondo. Ingqondo yethu ifumana ingcamango yomgama ngokutolika umehluko kumfanekiso ovela kwisehlo lasekunene nelinene. Oku kwaziwa ngokuba yi-binocular disparity.
- Ingxubusho epheleleyo malunga nendlela udibaniso lwe-3D oluziswa ngayo ubomi lunokufumana ixesha elide, kwaye akusiyo iforum efanelekileyo. Siza kukunika enye inkcazo yokugqibela, ekhonza njengesiseko sokuba iifilimu ze-3D zidalwa njani namhlanje:
- I-stereoscopy: Ukudala ukungaqondi kakuhle, abenzi bamabhayisikobho baye bahlakulela iindlela zokulinganisa ukungafani kwemibhobho . Iindlela eziqhelekileyo zokufezekisa oku kusebenzisa iindlela ezimbini okanye ezinye iindlela zokujonga ngokubambisana neziglasi ezigqithisiweyo eziqinisekisa ukuba iliso lesobunxele nelinene lifumana imifanekiso eyahlukileyo. Oku kwaziwa ngokuba yi- stereoscopy , ngoko ke i-term stereoscopic 3D .
Yaye unayo!
Ngethemba ngale ngongoma unolwazi oluncinane malunga ne-3D njengoko lubhekiselele kwimifanekiso yekhompyutha kunye nefilimu. Sifake ezinye izixhumanisi kumzimba wale nqaku, ezichaza ezinye zeengcamango ezenziwe ngokubanzi.
