I-Intel ishicilele ukukhishwa kwephrojekthi ye-oidn 2.5 (Open Image Denoise), ethuthukisa iqoqo lezihlungi zezithombe ezikhipha umsindo ezilungiselelwe kusetshenziswa amasistimu okunikezwa kwe-ray tracing. I-Open Image Denoise ithuthukiswa njengengxenye yephrojekthi enkulu ye-API Rendering Toolkit ehloselwe ukuthuthukisa amathuluzi okubona esofthiwe yesayensi (SDVis (Software Defined Visualization)), okuhlanganisa nelabhulali yokulandelela i-Embree ray, isistimu yokunikezela ngezithombe ze-GLuRay, iplathifomu esabalalisiwe ye-OSRay yokulandelela ama-ray, kanye ne-OpenSWR software+2.0 ishicilelwe ngaphansi kwelayisensi ye-Apache.
Le phrojekthi ihlose ukuhlinzeka ngezici zokususa umsindo ezisezingeni eliphezulu, ezisebenzayo, nezilula ukuzisebenzisa ezingasetshenziswa ukuthuthukisa ikhwalithi yemiphumela yokulandelela imisebe. Izihlungi ezihlongozwayo zivumela umphumela womjikelezo wokulandelela imisebe omfushane ukuthi utholakale ezingeni lekhwalithi yokugcina elifana nelendlela ebiza kakhulu.
kanye nenqubo ende yokuhumusha okuningiliziwe.
Vula i-Image Denoise ihlunga umsindo ongahleliwe njengokulandelela imisebe ye-Monte Carlo Numerical Integration (MCRT). Ukuze kuzuzwe ukunikezwa kwekhwalithi ephezulu kuma-algorithms anjalo, ukulandelelwa kwenani elikhulu kakhulu lemisebe kuyadingeka, ngaphandle kwalokho ama-artifact abonakalayo ngendlela yomsindo ongahleliwe avela esithombeni esiwumphumela.
Ukusetshenziswa kwe-Open Image Denoise kukuvumela ukuthi wehlise inani lezibalo ezidingekayo ngama-oda amaningana wobukhulu lapho ubala iphikseli ngayinye. Ngenxa yalokho, kungenzeka ukukhiqiza isithombe esinomsindo ekuqaleni ngokushesha okukhulu, kodwa bese usiletha kukhwalithi eyamukelekayo usebenzisa ama-algorithms okunciphisa umsindo ngokushesha. Ngezisetshenziswa ezifanele, amathuluzi ahlongozwayo angasetshenziswa ngisho nasekulandeleleni imisebe ehlangene ngokususa umsindo lapho undiza.
Umtapo wolwazi ungasetshenziswa ezifundweni ezahlukene zamadivayisi, kusukela kuma-laptop nama-PC kuya kuma-cluster node. Ukuqaliswa kulungiselelwe amakilasi ahlukahlukene ama-Intel CPU angu-64-bit ngokusekelwa kwemiyalelo ye-SSE4, AVX2, AVX-512, kanye ne-XMX (Xe Matrix Extensions), ama-Apple Silicon chips, kanye nezinhlelo ezine-Intel Xe GPUs (Arc, Flex, kanye nochungechunge lwe-Max), i-NVIDIA (esekelwe ku-Turing, Ampere, Ada Lovelace, Hopper, kanye ne-Blackwell architectures), kanye ne-AMD (esekelwe ku-RDNA2 (Navi 21), RDNA3 (Navi 3x), RDNA 3.5, kanye ne-RDNA4 architectures). Ukusekelwa kwe-SSE4.1 kushiwo njengesidingo esincane.
Izinguquko ezibalulekile ekukhishweni kwe-Open Image Denoise 2.5:
- Ukusebenza okuthuthukisiwe kakhulu kanye nokunciphisa ukusetshenziswa kwememori kuma-Intel GPU ngenjini ye-XMX (Xe Matrix eXtensions) kanye nama-Intel CPU anokusekelwa kwemiyalelo ye-AMX-FP16.
- Kungezwe i-API yokungenisa ama-semaphore angaphandle avela kuma-API ehluzo e-Vulkan kanye ne-Direct3D 12. Usekelo okwamanje lukhawulelwe kumadivayisi anikwe amandla yi-CUDA (ku Windows и Linux) kanye ne-HIP (ku Windows). Ukusekelwa kwamadivayisi e-SYCL kuzovela ekukhishweni kwesikhathi esizayo.
- Kungezwe ifulegi le-OIDN_EXTERNAL_MEMORY_TYPE_FLAG_DEDICATED lokungenisa imemori yangaphandle ezinikele.
