Ngexesha Icandelo lomdlalo wevidiyo liqala ukuphonononga Uluhlu lwamathuba olunikezelayo Ukuphuculwa kobuchwephesha bokulungiswa kwezithunzi kunye nokubonakaliswa, abaphuhlisi abazimeleyo bapapashe i-Q2VKPT (Quake II PATHTRACED).
Q2VKPT sisiphumo selinge lokubonisa ukuba yintoni enokuphunyezwa kwimidlalo elandelayo ngophunyezo lokutyhala kokulandela umkhondo we-ray.
I-Q2VKPT isekwe kumdlalo odumileyo weQuake 2 ukusukela ngo-1997, Le yi-Q2VKPT FPS ehambelana ngokupheleleyo nokulandela umkhondo wetekhnoloji sisisombululo seMizobo yeNVIDIA GPU evela kumenzi.
Le projekthi okwangoku ibandakanya malunga ne-12,000 yemigca yekhowudi kwaye ithathe indawo yekhowudi yemizobo yokuqala yeQuake II. Ekuqaleni, iprototype yayiyilwe phantsi kwe-OpenGL ngoncedo lwabasebenzi abaliqela.
Esi sihloko sikhulu isebenzisa iindlela ezahlukeneyo zobuchule bokuziqhelanisa kwimidlalo yeendlela zokubala ebezisetyenziswa ngaphambili zibiza kakhulu kumzi mveliso wefilimu.
Malunga neQ2VKPT
Le FPS isebenza kubandakanya indlela yokulandela umkhondo, ialgorithm ethatha ithuba lokulandela umkhondo we-ray, ukubala, kunye nefilitha yexeshana eguqukayo Ukuncitshiswa kwengxolo okuqhubela phambili, kunye nokulwa nokungasebenzi okwethutyana, okuphinda kusetyenziswe ngengqondo iziphumo zobalo lwangaphambili ukubonisa umfanekiso ococekileyo.
Njengesikhumbuzo, Kwakungexesha leNkomfa yabaPhuhlisi beMidlalo i-2018 ebibanjwe ngoMatshi ophelileyo apho i-NVIDIA yazisa itekhnoloji ye-RTXItekhnoloji yokulandela umkhondo we-ray eyenza ukuba abaphuhlisi bemidlalo kunye nabenzi bemxholo bahambise umgangatho weCinema ekunikezeleni ngexesha elifanelekileyo ukuzisa imihlaba ebonakalayo ebomini.
Ivumela ulawulo oluchanekileyo ngakumbi ngokuqaqamba, amagqabantshintshi, kunye nezithunzi ukubonelela ngemidlalo eyenzelwe ukuba icace ngakumbi kwaye isondele kwihlabathi lokwenyani.
Enkosi ngokulandela umkhondo we-ray, endaweni yokuzoba ingqikelelo yezinto ze-3D kwindiza yepikseli, silinganisa inyani ngokulandela indlela eyayiza kuthathwa yifoton eyayinokufikelela kwiliso lombonisi ukumisela umbala wayo oyinyani.
Oku kunika iinkcukacha ezithe kratya malunga nokufiphala kwemidlalo kumdlalo.
Iflegi yesi sizukulwana sitsha se-NVIDIA GeForce RTX 2080 Ti ene-4352 CUDA cores, i-11 GB yayo ye-GDDR6 VRAM, bandwidth ye-616 Gb / s, 272 TMU yayo, 88 ROPs kunye ne-TDP ye-250 watts.
Le GPU, ngokutsho komvelisi wayo, ukuya kuthi ga ngokuphindwe kathandathu ngokusebenza ngokubhekisele kubalo olunikezelwe ukulandelwa kwemitha kwaye ukuya kuthi ga ngokulishumi ngokusebenzayo kubalo olunxulumene nobukrelekrele bokuzenzela kunemijikelezo yemizobo ye-GTX yesizukulwana esidlulileyo.
Ngokweqela eliphethe uphuhliso lweQ2VKPT, lImidlalo yanamhlanje efana neBala leMfazwe V, nangona inzima ngakumbi ngokweenkcukacha, kukrwela kuphela amathuba anikezelwe ngumkhondo we-ray kwaye uxhomekeke kwimizobo esekwe kwimizobo.
Iprojekthi yakhe kufuneka ibonise ukuba kuninzi okunokufunyanwa.
Malunga nophuhliso yayo
I-Q2VKPT isusa izinto ezithile ze-2D kwimizobo ye-raster kwaye isebenzisa umkhondo wekhanyiso lomhlaba jikelele kwimithombo yokukhanya emileyo kunye namandla, kubandakanya imitha yokulandela umkhondo kunye nokukhanya okuqaqambileyo; Ubuncinane beams ezine kugxothwa nge-pixel nganye.
Sebenzisa izinto ezintsha zokulandela umkhondo kwimitha ezibandakanyiweyo kule FPS, Uya kuyidinga ikhadi lemizobo yale mihla Ngokwendalo ixhasa i-VK_NV_ray_tracing ulwandiso njenge-NVIDIA RTX GPUs ukusuka kulwakhiwo lweTuring.
I-Q2VKPT inokuthi, umzekelo, idlalwe kwii-60 FPS kwi-2560x1440 inkcazo enekhadi lemizobo le-NVIDIA RTX 2080Ti.
I-VKPT kunye ne-Q2VKPT zaphuhliswa nguChristoph Schied njengenxalenye yeprojekthi yolonwabo yokuqinisekisa uphando lwekhompyuter kwimizobo yevidiyo yakutshanje.
Uyifumana njani iQ2VKPT?
Kwabo banomdla wokuzama umdlalo lo, Ungaya kwiwebhusayithi esemthethweni yeprojekthi apho uya kufumana khona amakhonkco okhuphelo ikhowudi yemvelaphi yomdlalo ukuze ikwazi ukuyihlanganisa kwiLinux, ngelixa iWindows sele ikho indibaniselwano eyenziwe.
