Compania Intel a prezentat<\/a><\/noindex> lansare semnificativ\u0103 a unui motor 3D de randare scalabil OSPRay 2.0<\/a><\/noindex>, destinat vizualiz\u0103rii realiste de \u00eenalt\u0103 calitate prin ray tracing, adecvat pentru aplica\u021bii interactive.

OSPRay se concentreaz\u0103 \u00een principal pe utilizarea \u00een aplica\u021bii interactive pentru randarea scenei \u00een timp real. Pentru simularea comportamentului luminii se aplic\u0103 metoda ray tracing<\/a><\/noindex>.

OSPRAY folose\u0219te doar capacit\u0103\u021bile CPU, f\u0103r\u0103 a se lega de GPU, ceea ce permite utilizarea bibliotecii pe o gam\u0103 larg\u0103 de dispozitive, de la sta\u021bii de lucru la noduri \u00een clustere de calcul. Pentru a asigura performan\u021ba adecvat\u0103, se folose\u0219te intens multiprocesare \u0219i vectorizare pe baz\u0103 de instruc\u021biuni SIMD, cum ar fi Intel SSE4, AVX, AVX2, \u0219i AVX-512 (pentru func\u021bionarea OSPRay este necesar\u0103 cel pu\u021bin suportul SSE4.1).<\/a><\/noindex>«).<\/p>\n

Randarea poate fi distribuit\u0103 pe mai multe noduri ale clusterei (se suport\u0103 MPI), ceea ce, de exemplu, permite utilizarea OSPRay pentru organizarea rand\u0103rii imaginilor cu o foarte \u00eenalt\u0103 rezolu\u021bie pe <\/p>\n

videowall , o imagine unic\u0103 fiind creat\u0103 dintr-un set de panouri LCD individuale. De exemplu, func\u021bionarea OSPRay a fost demonstrat\u0103 pe un ecran compus<\/a><\/noindex>Stallion , compus din 80 de monitoare de 30 de inci (rezolu\u021bia total\u0103 de 40960\u00d78000 sau 328 de megapixeli) \u0219i servit de un cluster de 40 de servere cu CPU-uri cu 6 nuclee bazate pe microarhitectura Intel Sandy Bridge.<\/a><\/noindex>, compus din 80 de monitoare de 30 de inci (rezolu\u021bie total\u0103 40960×8000 sau 328 de megapixeli) \u0219i \u00eentre\u021binut de un cluster de 40 de servere cu CPU-uri cu 6 nuclee pe baza microarhitecturii Intel Sandy Bridge. <\/p>\n

O schimbare semnificativ\u0103 a num\u0103rului de versiune este cauzat\u0103 de o refacere ampl\u0103 a API-ului, inclusiv prin introducerea unor modific\u0103ri care \u00eencalc\u0103 compatibilitatea (pentru a simplifica trecerea la noul API, a fost propus\u0103 o bibliotec\u0103 intermediar\u0103 care faciliteaz\u0103 migrarea) \u0219i furnizarea de noi tipuri geometrice. A fost ad\u0103ugat\u0103 suportul pentru Open VKL (Open Volume Kernel Library) pentru randarea volumetric\u0103. A fost implementat\u0103 posibilitatea de conectare modulului<\/a><\/noindex> pentru reducerea zgomotului \u00een imagine.
