Med drugim se program lahko uporablja za visoko natan\u010dno upodabljanje zapletenih prizorov in obdelavo zelo velikih prizorov, ki zahtevajo porazdeljeno izvajanje izra\u010dunov v klasterju ve\u010d ra\u010dunalnikov. Koda aplikacije je napisana v programskem jeziku C++ in se distribuira pod licenco Apache 2.0. Za upodabljanje na zaslonu se uporablja OpenGL in knji\u017enica GLFW.      <\/p>\n<p>Prizor, ki ga je treba upodobiti, je mogo\u010de nalo\u017eiti v raz\u0161irjenih formatih ali ustvariti s pomo\u010djo vozli\u0161\u010d scene (scene graph). Podpirajo se modeli v formatu MTL z materiali za fotorealisti\u010dno upodabljanje, 3D animacije v formatu glTF, teksture v formatu UDIM, volumenski redki delci (npr. oblaki) v formatu VDB, oblaki to\u010dk v formatu PCD (Point Cloud Data), profili osvetlitve v formatu EULUMDAT (.ldt). Stanje grafika scene se lahko shrani ali nalo\u017ei v formatu JSON.       <\/p>\n<p>Raz\u0161irjena funkcionalnost, vti\u010dniki za uporabni\u0161ki vmesnik in obdelovalci za uvoz podatkov se lahko priklju\u010dijo v obliki vti\u010dnikov. Na voljo so na primer vti\u010dniki za vizualizacijo medicinskih podatkov v formatu DICOM, generiranje pokrajin po vi\u0161inski karti, obdelava velikih skupin standardiziranih objektov (trava, drevesa), simulacija astronomskih dogodkov, vizualizacija znanstvenih podatkov v formatu VTK itd.      <\/p>\n<p>Za simulacijo obna\u0161anja svetlobe je podprta uporaba metode sledenja poti. Vizualizacija se lahko izvaja v prostoru ali na ravnini. Podprto je fotorealisti\u010dno globalno osvetljevanje ob upo\u0161tevanju fizikalnih lastnosti materialov ter \u0161ir\u0161i u\u010dinki sencenja (sence, prosojnost in sencenje \"Ambient occlusion\"). Mo\u017eno je ustvarjanje scenarijev za izvajanje operacij v paketnem na\u010dinu, na primer za upodabljanje slik na sistemu brez zaslona, izbiro obmo\u010dij za upodabljanje, nastavitev kamere, parametrov upodabljanja in sceno.      <center>  <video controls=\"\" style=\"width: 700px; height: 400px; max-width:100%\"><source src=\"http:\/\/www.ospray.org\/ospray_studio\/images\/DizzyDrone15.mp4\" type=\"video\/mp4\"><\/video>  <\/center>      <\/p>\n<p>V novi razli\u010dici OSPRay Studio:  <\/p>\n<ul>\n<li class=\"l\"> Dodana je podpora za funkcionalnost motorja OSPRay, ki se je pojavila v izdaji 3.1.\n<li class=\"l\"> V uporabni\u0161ki vmesnik je vgrajena podpora za dodatne materiale, ki jih podpira motor OSPRay.\n<li class=\"l\"> Dodana je podpora za API OpenEXR v2.x in v3.x.\n<li class=\"l\"> Zagotavlja se dolo\u010danje sprememb datotek v asinhronem na\u010dinu za samodejno posodobitev tekstur.\n<li class=\"l\"> V API-ju za vti\u010dnike je omogo\u010den dostop do razredov MainWindow in ArcballCamera.\n<li class=\"l\"> V paketnem na\u010dinu je podprto porazdeljeno upodabljanje z uporabo MPI.  <\/ul>\n<p>Poleg tega lahko omenimo objavo nove razli\u010dice 3D-upodabljalnika OSPRay 3.1 pred nekaj dnevi, ki se uporablja v OSPRay Studio 1.0.  Upodabljalnik se razvija kot del ve\u010djega projekta Intel Rendering Framework, usmerjenega v razvoj sredstev programske vizualizacije znanstvenih izra\u010dunov SDVis (Software Defined Visualization), ki vklju\u010dujejo knji\u017enico sledenja \u017earkom Embree, sistem fotorealisti\u010dnega upodabljanja GLuRay, knji\u017enico za zmanj\u0161evanje \u0161uma na slikah oidn (Open Image Denoise) in sistem programske rastracije OpenSWR. Koda je napisana v jeziku C++ in objavljena pod licenco Apache 2.0.    <\/p>\n<p>OSPRay je predvsem usmerjen na uporabo v interaktivnih aplikacijah za upodabljanje prizorov v realnem \u010dasu. Upodabljalnik lahko deluje brez vezave na GPU, kar omogo\u010da uporabo knji\u017enice na \u0161irokem spektru naprav, od delovnih postaj do vozli\u0161\u010d v ra\u010dunalni\u0161kih grozdih. Za zagotavljanje ustrezne zmogljivosti se aktivno uporablja ve\u010dnitnost in vektorizacija na podlagi SIMD-navodil, kot so Intel SSE4, AVX, AVX2 in AVX-512. Upodabljanje je lahko razdeljeno na ve\u010d vozli\u0161\u010d grozda (podprta je MPI), kar na primer omogo\u010da uporabo OSPRay za organizacijo upodabljanja slik z zelo visoko lo\u010dljivostjo na video stenah, kjer se eno samo sliko oblikuje s kompletom lo\u010denih LCD-panelov.    <\/p>\n<p>Med izbolj\u0161avami v OSPRay 3.1:  <\/p>\n<ul>\n<li class=\"l\"> Podpora za uporabo sevalnih tekstur s svetle\u010dimi materiali.\n<li class=\"l\"> Med podprte sferi\u010dne objekte so dodani \"disk\" (OSP_DISC) in \"usmerjeni disk\" (OSP_ORIENTED_DIS).\n<li class=\"l\"> Dodani so na\u010dini zrcaljenja in prekrivanja teksture na robu (edge texture wrap).\n<li class=\"l\"> Za vse teksture je dodana podpora za na\u010din OSPTextureWrapMode.\n<li class=\"l\"> Zagotovljena je popolna podpora za ovijanje tekstur v formatu glTF.\n<li class=\"l\"> Dodana je podpora za zmanj\u0161anje \u0161uma in prilagoditev tonov za podatke v predpomnilniku.\n<li class=\"l\"> Pri uporabi GPU je implementirana podpora za zameglitev premikajo\u010dih se predmetov (motion blur).      <\/ul>\n<p>Izvor: <a content=\"nofollow\" rel=\"nofollow\"
