OSPRay inoratidzira scalable CPU uye GPU kupa kugona
Intel yakavhurwa munguva pfupi yapfuura yakatanga injini yayo yekupa 3D, OSPRay 3.0, inova scalable 3D rendering injini yakagadzirirwa yemhando yepamusoro, yechokwadi kupa ine ray tracing.
Zvinonzi injini iyi yekupa Inonyanya kuitirwa kuti ishandiswe mumashandisirwo ekuita kuita zviitiko panhunzi. Kutevedzera maitiro echiedza, nzira yekutevera nzira inoshandiswa.
Inotsigira kuratidzwa muvhoriyamu uye mune imwe ndege, photorealistic global illumination uchifunga nezve inofunga nezvezvinhu zvemuviri zvezvinhu, advanced shading effects. OSPRay inogona kumhanya isina kusungirirwa kuGPU, ichibvumira raibhurari kuti ishandiswe pamhando dzakasiyana siyana dzemidziyo, kubva kunzvimbo dzekushandira kusvika kumanodhi mumasumbu emakomputa.
Kuti tive nechokwadi chekuita zvakanaka, multithreading uye vectorization yakavakirwa paSIMD mirairo iri kushingaira kushandiswa, seIntel SSE4, AVX, AVX2 uye AVX-512 (OSPRay inoda SSE4.1 tsigiro kanenge).
Kupa kunogona kugoverwa munzvimbo dzakasiyana-siyana muboka (MPI inoenderana), iyo, semuenzaniso, inobvumira OSPRay kuti ishandiswe kuronga kupa kwemifananidzo yakakwira kwazvo pamadziro evhidhiyo, mufananidzo mumwechete umo seti yemifananidzo inoumbwa yakaparadzaniswa. .
Chii chitsva muOSRay 3.0?
Mune iyi vhezheni itsva yeOSRay inoratidzwa, inosimbiswa kuti Sarudzo yekuyedza yaitwa kushandisa Intel Xe GPU (Intel Arc ™ GPU, Intel Data Center Flex GPU, uye Max Series GPU) yekumhanyisa hardware yekutevera ray. Zvinotaurwa kuti rutsigiro rweGPU runoitwa uchishandisa iyo SYCL layer, iyo inokutendera iwe kugadzira maapplication muC ++.
Zvakakodzera kutaura izvozvo Izvi zvinotevera hazvisati zvaitwa kana kusashanda nemazvo: Mavhoriyamu akawanda muchiitiko, Clipping, Motion blur, Subdivision nzvimbo, Taura mafambiro kuburikidza neospGetProgress, kukanzura furemu kuburikidza neospCancel, Kunhonga kuburikidza neospPick, Adaptive Accumulation kuburikidza neOSP_FB_VARIANCE uye varianceThreshold uye OSP_FB_ID_* framebuffer channels (ID buffers).
Dzimwe shanduko dzinomira pachena ndedzekuti yakawedzerwa kurongeka kwepolygonal mesh "meshla" geometry, pamwe nerutsigiro rwekuendesa muridzi wenguva pfupi buffers uye optimizations yeMPI module, inotsigirwa nehutsva hwakabatanidzwa hwekutarisa maitiro.
Ukuwo, kunotaurwa kuti Yakagadziriswa simba rekuchengetedza ye "Pricipled" zvinhu pasi pemamwe masanganiswa emaparamita, pamwe nekugadziriswa mu denoiser kuti usadzima alpha chiteshi uye kugadzirisa HDRI kutadza kwemwenje.
Zvevamwe shanduko dzinomira pachena:
- Yakagadziridzwa gradient zadza muSciVis renderer.
- Shanduko dzakaitwa kune iyo API iyo inotyora kuenderana. Tsigiro yemaparamita enhaka uye mafoni akamiswa.
- Gadzirisa yekubatanidza odha yedebug kuvaka paWindows
- New zvishoma kutsamira shanduro: Embree v4.3.0, Vhura VKL v2.0.0, Open Image, Denoise v2.1.0, ISPC v1.21.1 uye rkcommon v1.12.0
- Yakabviswa maparamita echinyakare uye API inofona senge kukanganisa callback siginecha isina mushandisi pointer, mabasa chinjana
vec2f valueRange; pfekabox1f value - Zvinonzi Multidevice haitsigire OSPImageOperationmessages yekubvisa ruzha kana toni mepu
- Kune imwe musanganiswa wemuunganidzi, mutyairi weGPU, uye chiitiko, mifananidzo yakapihwa inogona kuratidza zvigadzirwa (semuenzaniso, mitsetse yakatwasuka kana mabhuroko madiki)
Kune avo vanofarira kudzidza zvakawanda nezvazvo, iwe unofanirwa kuziva kuti injini iri kuvandudzwa sechikamu cheIntel Rendering Framework chirongwa, chine chinangwa chekugadzira maturusi ekuona maturusi ekuverenga kwesainzi SDVis (Software Defined Visualization).
Pakati pemapurojekiti anosanganisirwa, iyo Embree ray tracing library, iyo GLuRay photorealistic rendering system, iyo oidn image denoising raibhurari inotaurwa. (Vhura Mufananidzo Denoise) uye OpenSWR software rasterization system. Iyo kodhi yakanyorwa muC ++ uye yakabudiswa pasi rezinesi reApache 2.0.
Chekupedzisira, kana iwe uchida kukwanisa kuziva zvakawanda nezvazvo, unogona kubvunza iwo ruzivo mu inotevera chinongedzo.
