CUDA...opet
This demo was presented by Chaos Group on August 6, 2009 at the SIGGRAPH 2009 Chaos Group User Event. During the event the first public showing of their GPU rendering tests were presented to a packed house. This video showcases the recently released V-Ray RT using an NVIDIA GeForce 285 GPU. While this GPU verson is not a shipping product yet, already this technology demo features rendering speeds and quality surpassing all of the current GPU rendering applications that we've seen to date. Several high level industry representatives in attendance commented that this demo was the highlight of SIGGRAPH 2009.
To se ceka...V-ray dobija GPU akceleraciju, fakin fantastik! RealTime opcija u novom V-rayu dobija smisao, jer bez GPU akceleracije ne vredi bez minimum 8 jezgara na raspolaganju.

Da dodam, V-Ray, kao (najpopularniji) render plugin za modeling alate, ovim potezom ozbiljno narusava "bazu" korisnika koja je koristila high-end CPU-ove i masine sa 2 socketa, i render farme sacinjene od istih. Procesori sa cenom kakva je ova ce najzad biti proslost kad je rec o ljudima/firmama koje se bave renderovanjem i ciji posao zavisi od brzine (a cinili su prilicno trziste za prodaju skupih procesora).
Graficka kartica koja je prilicno jeftinija daje 20x puta bolje rezultate. Multi-GPU dobija novi smisao, kao i koriscenje GPU-a za ozbiljnije poslove. Bilo je GPU akcelerisanih aplikacija i ranije, neke rade na obicnim karticama, neke traze profi verzije istih (quadro), i uglavnom ne daju zadovoljavajuce rezultate, pa se neki ozbiljan "proboj" cekao.
I dogodio se...Chaos Group je ponovo napravio korak unapred, u pravom smeru. Za mene je ovo -pa, vest godine![]()
...jos samo da se "razrese" stvari oko memorije, da uposljava svu raspolozivu (i graficku i sistemsku)...steta da se bace ovi nasi gigabajti![]()
CPU Vs GPU ? No, thanks, CPU + GPU + Network rendering is better
One of the fundamental aspect planned while introducing OpenCL in Luxrender was to not lose any of the feature available. It means GPGPU will be just an addition to the wide set of features available to reduce the rendering time. You will still able to spawn multiple rendering threads to take advantage of your multi-core CPUs and to use Network rendering in order to let multiple computers to work on the same image. You will be able to finally take advantage of the GPUs available on a single computer and/or among all computers available on your networks.
