I-3D Computer Graphics, ifilimu, ne-All Import Z-Axis ebalulekile
Ukuhlola ihluzo zekhompyutha ye-3D okokuqala, kungakhathaliseki ukuthi unentshisekelo kwifilimu ye-3D, imiphumela ebonakalayo ye- 3D, noma ukukhiqizwa kwe-animation kanye / noma imidlalo yevidiyo? Lesi isingeniso esibanzi ku-3D, ngakho sizochaza leli gama ngomqondo jikelele, uchaze ukuthi lihlobene kanjani nezinsiza kanye nezihloko ezikuleli sayithi, futhi ikunike umbono wokuthi ungabheka kuphi olunye ulwazi.
Ngakho, Kuyini i-3D?
Ngencazelo ebanzi yeli gama, i-3D ingachaza noma iyiphi into eyenzeka ohlelweni lokuxhumanisa lwe-Cartesian e-axis amathathu. Uma lokho kuzwakalisa i-tad yobuchwepheshe, ungesabi - sizokusula ngokushesha.
I-Cartesian system coordinate system iyindlela elula yokuchaza izixhumi ze-X ne-Y sonke esizijwayele kusukela geometry esikoleni esiphakeme (cabanga iphepha legrafu).
Uyakhumbula ukwenza amancane amashadi kanye namashadi nge-X axis enqamule, futhi i-Y axis ibe mpo, kunjalo? Izinto zifana kakhulu ezweni le-3D, ngokuhlukile - kukhona i-axis yesithathu: Z, emele ukujula .
Ngakho ngencazelo, noma yikuphi into engaboniswa ohlelweni lwe-axis amathathu i-3D. Lona akuyona indaba yonke, yebo.
I-3D kuhlobene Nezithombe zekhompyutha
Kungenzeka ukuthi ufunda lokhu ngoba unesithakazelo esidlule esivela ku-3D njengoba kubhekiselwa embonini yekhamera yekhompyutha , okubandakanya ifilimu, ithelevishini, ukukhangisa, ubunjiniyela, nokuthuthukiswa kwegeyimu yevidiyo.
Amaphuzu ambalwa abalulekile kwihluzo zekhompyutha ze-3D:
- Incazelo eyisisekelo yesikhala se-3D ihlala efanayo: Konke okuphathelene ne-X, Y, ne-Z-axis kusenjalo, kodwa kukhona okunye okubambe. Ngenkathi izinto zangempela zezwe ze-3D zikhona ngokomzimba ngobukhulu obuthathu, ezweni ledijithali yezinto ze-computer ihluzo ze-3D zingamelwa kuphela ngezibalo .
- Amamodeli we-3D: Noma yikuphi ukumelelwa kwento ku-space space, kubizwa ngokuthi i- 3D model . Uma ubheka ukwaziswa okuluhlaza okuqukethe imodeli eyisisekelo ye- 3D , kungamane (noma kungenjalo nje) kube iqoqo lamaphuzu wedatha aphawula izinkulungwane noma izigidi zezixhumanisi ezihlukile esikhala seCaresia.
- Isofthiwe yenza izibalo: Ngenhlanhla kubaculi, i-software ye-3D isebenzelana nezibalo eziningi ezinzima. Ngaphakathi kwesikhombikubona somsebenzisi se-graphic yephakheji ye- 3D efana ne-Autodesk 3ds Max noma iMaya , i- 3D imodeli ihunyushwa ngokuzenzakalelayo futhi ibonakala ngokubonakalayo njengezinto ze-geometri ezenziwe ngamaphethelo, ama-vertices, nama-polygonal. Izindawo eziningi ze-software zakhiwe ngesikhathi sangempela zinikeza izinjini ezikwazi ukubonisa amamodeli we-3D ngokukhanyisa okungokoqobo, izithunzi, nokuthungwa.
Okuningi Ku-Z-Axis:
Kusukela i-Z-axis isici esibalulekile salesi sikhala se-3D, ake sihlolisise ukuthi yikuphi "iZ" okusho ngempela kwimvelo yesofthiwe ye-3D. Ukuxhumanisa kweZ kungasetshenziswa ukukala izinto ezine kuhluzo lwekhompyutha ye-3D:
- Ukujula kwezinto ngokusayizi . Njengalokhu, ama-5 amayunithi ahlukene, amayunithi angu-4 ubude, nama- 3 amayunithi ajulile .
- Indawo yento ngokuphathelene nomsuka. Imvelaphi kunoma yisiphi isici se-3D (0,0,0) nenani lesithathu ngokuvamile "Z". Kunamaphakheji amancane amancane e-3D asebenzisa i-Z njenge-axis eqondile, kodwa lezi zimo azivamile.
- Ibanga lento evela ku-ikhamera ekhonjisiwe , eyaziwa kwihluzo zekhompyutha njenge-z-depth. U-Z-Ukujula kuvame ukusetshenziswa ukusebenzisa ukujula kwemiphumela yasensimini ekukhiqizeni ngemuva, futhi kumageyimu wevidiyo usetshenziselwa ukulungiswa kwezinga lezinombolo.
- I-axis e-Z yokujikeleza . Isibonelo, ibhola eligeleza ikhamera lingasho ukuthi lijikeleza nge-Z-axis engalungile.
I-3D ekuhlobene nefilimu / ifilimu:
Igama elithi 3D lisho into ehluke ngokuphelele uma isetshenziselwa ukubhekisela kumabhayisikobho e-3D (uhlobo oludinga ukuthi ugqoke izibuko futhi wenze ukuthi ufuna ukuphuma bese uzama ukuthinta izinto eziphuma esikrinini). Amafilimu e-3D angakwazi futhi abe nesici se-3D ihluzo zekhompiyutha, kodwa kunezinhlobo eziningi zamafilimu adutshulwa, okungezona-CG asetshenziselwe ukuvuselelwa kwamuva kwe-3D cinema.
Isici esichazayo se "3D" njengoba sicabanga ngakho emidlalo yaseshashalazini (futhi manje eseshashalazini yasendlini ), ukuthi abenzi befilimu kumele basebenzise ezinye izindlela zokukhohlisa uhlelo lokubonwa komuntu zibe umbono wokungaqondakali wokujula.
- Ukungafani kwe-Binocular: Isihluthulelo ekuboneni ukujula komuntu sithinta konke ukuthi amehlo ethu athumela isithombe esivelele ebuchosheni. Ubuchopho bethu buthola umbono webanga ngokuhumusha umehluko esithombeni kusuka kweso lesobunxele nelesokudla. Lokhu kwaziwa ngokuthi ukungafani kwe-binocular.
- Ukuxoxwa okugcwele mayelana nokuthi i-3D inkohliso ivuliwe kanjani ingazuza isikhathi eside, futhi lokhu akusona isithangami esifanele. Sizokunikeza incazelo eyodwa yokugcina, ekhonza njengesisekelo sokuthi ama-3D amafilimu adalwa kanjani namuhla:
- I-Stereoscopy: Ukwenza ukungaqondi kahle kokujula, abenzi befilimu kuye kwadingeka bahlakulele izindlela zokulinganisa ukungafani kwamabhayisikili . Izindlela ezijwayelekile zokufeza lokhu ukusebenzisa ama-double noma ukushintsha izinhlelo zokuqapha ngokubambisana nezibuko ezigcizelelayo eziqinisekisa ukuthi iso lesobunxele nelungile lithola njalo isithombe esithile. Lokhu kwaziwa ngokuthi stereoscopy , ngakho-ke i-term stereoscopic 3D .
Futhi lapho unakho!
Ngethemba ngaleli phuzu unolwazi oluthe xaxa mayelana ne-3D njengoba lihlobene nehluzo zekhompyutha nefilimu. Sifake izixhumanisi ezithile emzimbeni walesi sihloko, okuchaza ezinye zezinkulumo ezivezwe ngokujulile okukhulu.
