Tvrtka Intel predstavila<\/a><\/noindex> zna\u010dajan izlaz skalabilnog 3D renderiraju\u0107eg motora OSPRay 2.0<\/a><\/noindex>, namijenjenog za realisti\u010dnu visoko kvalitetnu vizualizaciju metodom pra\u0107enja zraka, prikladnog za primjene u interaktivnim aplikacijama. Motor se razvija kao dio ve\u0107eg projekta Intel Rendering Framework<\/a><\/noindex>, usmjerenog na razvoj alata za programski vizualizaciju znanstvenih izra\u010duna SDVis<\/a><\/noindex> (Software Defined Visualization), uklju\u010denih bibliotekom za pra\u0107enje zraka Embree<\/a><\/noindex>, sustavom fotorealisti\u010dnog prikaza GLuRay<\/a><\/noindex>, bibliotekom za uklanjanje \u0161uma s slika oidn (Open Image Denoise)<\/a><\/noindex> i sustavom programske rasterizacije OpenSWR<\/a><\/noindex>. Kod je napisan na C++ jeziku i objavljeno<\/a><\/noindex> pod licencom Apache 2.0.<\/p>\n

OSPRay je prvenstveno usmjeren na kori\u0161tenje u interaktivnim aplikacijama za prikazivanje scene u stvarnom vremenu. Za simulaciju pona\u0161anja svjetlosti koristi se metoda pra\u0107enja putanje<\/a><\/noindex>. Podr\u017eava vizualizaciju u volumenu i na ravnini, fotorealisti\u010dno globalno osvjetljenje<\/a><\/noindex> uzimaju\u0107i u obzir fizi\u010dka svojstva materijala, pro\u0161ireni efekti sen\u010denja (sjene, prozirnost i sen\u010denjeAmbient occlusion<\/a><\/noindex>«).<\/p>\n

OSPRay koristi samo CPU mogu\u0107nosti, ne oslanjaju\u0107i se na GPU, \u0161to omogu\u0107ava kori\u0161tenje biblioteke na \u0161irokom spektru ure\u0111aja, od radnih stanica do \u010dvorova u ra\u010dunalnim klastra. Za osiguravanje odgovaraju\u0107e izvedbe aktivno se koristi vi\u0161edretvenost i vektorizacija na bazi SIMD instrukcija, kao \u0161to su Intel SSE4, AVX, AVX2 i AVX-512 (za rad OSPRay minimalno je potrebna podr\u0161ka za SSE4.1). <\/p>\n

Renderiranje mo\u017ee biti distribuirano na nekoliko \u010dvorova klastera (podr\u017eava se MPI), \u0161to, na primjer, omogu\u0107uje kori\u0161tenje OSPRay za organizaciju prikazivanja slike s vrlo visokom rezolucijom na videopanelima<\/a><\/noindex>, jedinstvena slika koja se formira skupom pojedina\u010dnih LCD panela. Na primjer, rad OSPRay-a demonstriran je na sastavljenom ekranu Stallion<\/a><\/noindex>, sastavljenih od 80 30-in\u010dnih monitora (ukupna rezolucija 40960×8000 ili 328 megapiksela) i servisiranog klasterom od 40 servera s 6-jezgrenim CPU-ima temeljenim na mikroarhitekturi Intel Sandy Bridge. <\/p>\n

\"Intel<\/a><\/noindex><\/center><\/p>\n

Zna\u010dajna promjena oznake verzije posljedica je velike revizije API-ja, uklju\u010duju\u0107i izmjene koje naru\u0161avaju kompatibilnost (kako bi se olak\u0161ao prijelaz na novi API, ponu\u0111ena je slo\u017eena biblioteka koja ubla\u017eava migraciju), te pru\u017eanjem novih geometrijskih tipova. Dodana je podr\u0161ka za Open VKL (Open Volume Kernel Library) za 3D rendering. Implementirana je mogu\u0107nost povezivanja modula<\/a><\/noindex> za suzbijanje \u0161uma na slici. U posebne repozitorije izdvojene su biblioteka ospcommon i modul za podr\u0161ku MPI.<\/p>\n
