Imidlalo yevidiyo nobuchwepheshe buthuthuka ngesivinini esikhulu, futhi imigomo namasu amasha abonakala ezuza kakhulu engxenyeni ngayinye. Phakathi kwezinto ezintsha, kuphakama umbuzo mayelana yini iRay Tracing, isetshenziselwa ini futhi isebenza kanjani.
Incazelo elula ithi ubuchwepheshe obusetshenziswa thuthukisa ukukhanya, izithunzi kanye nemiphumela yokubonisa emidlalweni yevidiyo. Kodwa ngaphezu kwalokho, lobu buchwepheshe bumele enye yezinto ezichazwe kakhulu emakhadini ezithombe zesizukulwane sakamuva namakhonsoli egeyimu yevidiyo. Funda ukuze ufunde kabanzi mayelana nobubanzi nokuthi iyini i-Ray Tracing.
Kuyini uRay Tracing, ama-algorithms nobuchwepheshe
Igama ngeSpanishi lobu buchwepheshe lizoba "ukulandelela ama-ray". Ngokuvamile, i-algorithm ekhethekile esiza ukuthatha amaphoyinti ereferensi ahlukene endaweni ukuze uthole izithunzi ezingokoqobo kanye nemiphumela yokukhanyisa. Ngenkathi okutholayo kuyizindawo ezinhle kakhulu, kugcina kuthinta Ukusebenza kwe-FPS womdlalo.
umenzi wekhadi lezithombe I-NVIDIA yayisivele iqalile ukwenza i-algorithm yokulandela umsebe emakhadini ayo okuqala. Kodwa-ke, ukulinganiselwa kwezobuchwepheshe kuvimbele ukukhululwa kwayo emakethe kuze kube ngu-2018. Ukubandlulula amakhadi asekela i-Ray Tracing, ekhiqizwa ngaphansi kwe-architecture ye-Turing, igama lashintshwa kusukela ku-GTX kuya ku-RTX. Okusho ukuthi, yonke i-NVIDIA RTX inokusekelwa kweRay Tracing.
Ukuqonda ukuthi uRay Tracing usho ukuthini ukuqonda ama-Tensor Core cores amasha wamakhadi e-NVIDIA. Lawa amayunithi amasha okucubungula anikezelwe ngokukhethekile ukubala izithunzi nokuboniswa kwento ngayinye ekhona endaweni. Imidlalo yevidiyo kufanele ihambisane nalesi simiso se-algorithm, futhi ngokuvamile ekucushweni kwangaphakathi kwesihloko ngasinye kuba nokwenzeka noma cha ukwenza le miphumela isebenze.
Intuthuko yentuthuko ekusetshenzisweni kweRay Tracing
Ngokuvumelana nalokho okubonwe eminyakeni yamuva nje, imidlalo yevidiyo iqhubekela ekwamukelweni okukhulu kwale algorithm. Phakathi kwemidlalo yakamuva yevidiyo enokwesekwa ukuze ubone ngeso lengqondo ukuthi uRay Tracing uyini, sithola:
- Izinja ezigadayo
- Metro Exodus
- Ibutho lempi V
- Minecraft
- I-Call of Duty: Impi Yesimanje (2019)
Yiziphi izinzuzo uRay Tracing anazo?
Izizathu ze faka lobu buchwepheshe emidlalweni yethu yevidiyo esiyintandokazi Ikakhulukazi iwubuhle. Izinga lezithunzi kanye nemiphumela yokukhanya kwemvelo nezinto ziphakeme kakhulu, futhi ziyaziswa ikakhulukazi ekudutshulweni nasezigcawini ezinezenzo eziningi nokunyakaza. Emidlalweni yokuzidela neyokuhlola, ukukhanya phakathi kwezitshalo ehlathini kungazuza kakhulu ngalolu hlobo lwe-algorithm.
Ngenkathi unjiniyela we-NVIDIA ezihambela phambili, imbangi I-AMD iphinde yethula ihluzo nge-RDNA 2 Architecture lokho kusekela ukulandelela imisebe. I-PlayStation 5 kanye ne-Xbox Series X zinalawa makhadi futhi anikeza umbukwane wokubukwayo kanokusho mayelana nokukhanya nokufiphaza.
Ubuchwepheshe empeleni bemidlalo yevidiyo
Ngenxa yokuklama nokusetshenziswa kwayo, Ubuchwepheshe be-Ray Tracing bugxile ikakhulukazi ekuthuthukiseni isigaba esibonakalayo semidlalo. Okunye ukuhlolwa kokusebenza okuqondile, noma amabhentshimakhi, nawo enziwe ukuze kuqhathaniswe umthamo wamakhadi nale algorithm.
Okwamanje, amakhadi ezithombe anamandla kakhulu asenenkinga yokugcina amazinga e-FPS aphezulu uma i-Ray Tracing inikwe amandla. Phakathi kwabaklami begeyimu, ukugcina izinga eliphezulu le-FPS lokushelela kudlangile, ngakho-ke iRay Tracing isakhula. Eminyakeni ezayo, imizamo izogxila ekuthuthukiseni ukusebenza kwemidlalo yevidiyo enezilungiselelo eziphezulu zokusebenza ezinemifanekiso.
Indlela uRay Tracing esebenza ngayo esihlokweni
I-algorithm enikeza igama lobuchwepheshe beRay Tracing iwuhlelo ilingisa indlela yemisebe yokukhanya. Inhloso ukulandelela uhambo lomphumela wokukhanya nokusabela kwakho engxenyeni ngayinye yesikhala, ukusuka kumuntu ukuya edwaleni noma esihlahleni. Ukulingiswa kwakho konke ukusebenzisana okungenzeka kuyinkimbinkimbi kakhulu, ngakho-ke ubuchwepheshe buhlose ukukhiqiza izithombe ezingokoqobo.
Ukuze ubone ngeso lengqondo umphumela, ungavakashela i- igalari yemidlalo yama-epic lapho bekhombisa imiphumela ehlukile yendabuko yenjini yabo ye-Unreal Engine. Futhi, ungabona umthelela womphumela esihlokweni. Lokhu kuqhathanisa kuyiphuzu eliqinile lobuchwepheshe, njengoba izinguquko phakathi kwesithombe esine-Ray Tracing noma esingenayo ziyamangalisa.
Iziphetho
Noma kunjalo Ubuchwepheshe beRay Tracing busafuna kakhulu, izingxenye zandisa ikhwalithi yazo usuku nosuku. Umdlalo wevidiyo nekhonsoli kanye nabathuthukisi bamakhadi ezithombe bahlose ukusetshenziswa kwawo okuvamile. Imiphumela yokukhanyisa kanye ne-shading ishintsha kakhulu umbono wendawo. I-NVIDIA ne-AMD zisebenza kanzima ukuze ziqhubeke nokusetshenziswa, okuthinta i-FPS kancane ngangokunokwenzeka, ngakho-ke kufanele sibhekisise izinguquko nokusebenza kwalobu buchwepheshe esikhathini esimaphakathi.
