I-Dreamworks ikhiphe ikhodi yesistimu yokunikeza i-MoonRay

Kwavela izindaba zokuthi isitudiyo sopopayi esidumile I-Dreamworks yenze isinqumo sokukhulula ikhodi yesistimu yokunikezela inyanga, esebenzisa i-Monte Carlo Numerical Integration (MCRT)-based ray tracing.

Isistimu yakhelwe kusukela phansi kuya phezulu, ayincikile ekhodini yefa, futhi isilungele ukudala imisebenzi yobude besici obungcweti.

Idizayini yokuqala igxile ekusebenzeni okuphezulu kanye nokulinganisa, okuhlanganisa ukusekelwa kokuhumusha okunemicu eminingi, ukufana kokusebenza, ukusetshenziswa kwemiyalelo ye-vector (i-SIMD), ukulingisa ukukhanya okungokoqobo, ukucutshungulwa kwe-ray ohlangothini lwe-GPU noma lwe-CPU, ukulingisa okungokoqobo kokukhanyisa okusekelwe emzileni olandelelwe, ukumelwa kwezakhiwo zevolumu (inkungu, umlilo, amafu).

"Sijabule kakhulu ukwabelana nemboni eminyakeni eyi-10 yokusungula izinto ezintsha kanye nentuthuko kuMoonRay's vectorized, threaded, parallel and distributed codebase," kusho u-Andrew Pearce, iPhini Likamongameli.

“Umdlandla wokunikela ngezinga eliphezulu uyakhula minyaka yonke, futhi iMoonRay ikulungele ukuhlangabezana naleso sidingo. Sibheke ngabomvu ukubona isisekelo sekhodi sikhula ngamandla ngokuzibandakanya komphakathi njengoba i-DreamWorks iqhubeka nokukhombisa ukuzibophezela kwethu emthonjeni ovulekile. "

Ukuhlela ukunikezwa kusatshalaliswa Kusetshenziswa uhlaka lwalo lwe-Arras, lokho kukuvumela ukuthi usabalalise izibalo kumaseva amaningi noma ezindaweni zamafu. Ukunikezwa kwemishini eminingi kusheshisa ukuboniswa okusebenzisanayo kweciko ngokunqamula ukunikezwa okuvela kuthuluzi elisebenzisanayo okwandisa ukuqina okusebenzisanayo.

Isebenzisa i-MoonRay ne-Arras kumodi yokuqukethwe okuningi, umdwebi angakwazi ngesikhathi esisodwa ukubona izimo zokukhanya eziningi, izici ezibonakalayo ezihlukahlukene, izikhathi eziningi ngokudubula noma ukulandelana, noma ngisho nezindawo eziningi endaweni.

Ukuze uthuthukise izibalo zokukhanyisa ezindaweni ezisabalalisiwe, ingasetshenziswakumtapo wolwazi wokulandela umkhondo I-Intel Embree kanye ne-Intel ISPC compiler ukwenza i-vectorize shaders. Kuyenzeka ukuthi umise ukunikeza ngesikhathi esinqunyiwe futhi uqalise kabusha ukusebenza endaweni ephazanyiswe.

“Siyaziqhenya ngokusebenzisana kwethu eduze ne-DreamWorks on MoonRay ngomkhondo wayo ohlaba umxhwele we-photorealistic ray onikezela ukusebenza osekelwa yi-Intel Embree kanye nomthombo ovulekile we-Intel I-Implicit SPMD Compiler (Intel ISPC), zombili zisatshalaliswa ku-Intel oneAPI Rendering. 

I-Intel ibheke ngabomvu emathubeni amasha okusebenzisa i-OneAPI cross-architecture, ukwesekwa kwabathengisi be-cross-vendor kule phrojekthi yomthombo ovulekile wabo bonke abadali, "kusho uJim Jeffers, umqondisi omkhulu, unjiniyela omkhulu oyinhloko, ukulandelwa kwe-ray okuthuthukisiwe, i-Intel.

Iphakheji ihlanganisa nelabhulali enkulu yama-PBR ahlolwe ukukhiqiza kanye nesendlalelo se-USD Hydra Render Delegates ukuze sihlanganiswe nezinhlelo zokudala okuqukethwe kwe-USD yefa.

Izindlela zokuthatha izithombe eziningi zingenzeka, kusuka ku-photorealistic kuya kwesitayela esiphezulu. Ngosekelo lokunikezwa okusabalalisiwe, ama-animators angakwazi ukuqapha ngokuhlanganyela okukhiphayo futhi ngesikhathi esisodwa anikeze izinguqulo eziningi zesigcawu ngezimo ezihlukene zokukhanya, izici zento ezihlukile, kanye nemibono ehlukene.

Izici ze-MoonRay ezinjengokukhishwa kwezinwele noboya zathuthukiswa ngokubambisana ne-Intel. Izithuthukisi eziwumphumela zifakiwe kumtapo wezincwadi we-Intel Embree ray tracing kernel futhi ziyisibonelo sokuthi ukusebenzisa isofthiwe evulekile kuzuzisa kanjani yonke i-ecosystem. Ngokwamukela i-Intel ISPC, i-MoonRay isebenzisa ukufana kwe-vector yemiyalo ukuze kuzuzwe ukuthuthukiswa kokusebenza okumangalisayo.

Njengoba sekushiwo, i-MoonRay isebenzisa uhlaka lwekhompyutha olusabalalisiwe lwe-DreamWorks, Arras, ukuthi izophinde ifakwe kusisekelo sekhodi yomthombo ovulekile, ukuhlinzeka ngosekelo olusha lwemishini eminingi nezimo eziningi.

Umkhiqizo wasetshenziselwa ukunikeza amafilimu opopayi "Indlela Yokuqeqesha Udrako Wakho 3", "The Croods 2: Housewarming", "Bad Boys" kanye "Ne-Puss in Boots 2: The Last Wish". Okwamanje, isiza sephrojekthi esivulekile sesivele sethuliwe, kodwa ikhodi ngokwayo ithenjiswe ukuthi izoshicilelwa kamuva ku-GitHub ngaphansi kwelayisensi ye-Apache 2.0.

Ekugcineni, Uma unesifiso sokwazi okwengeziwe ngakho, ungabheka imininingwane kufayela le- isixhumanisi esilandelayo.
