SmallLuxGPU 2.0 Preview (OpenCL)

SmallLuxGPU is a LuxRays (http://www.luxrender.net/wiki/index.php?title=LuxRays) demo and a LuxRender (http://www.luxrender.net) "proof of concept".

The video was recorded on a i7 860 + 2xHD5870 + HD5850 at the resolution of 1920x1200.

SmallLuxGPU and LuxRays are released under GPL license and the sources are available at http://src.luxrender.net/luxrays/. Precompiled binaries are available on LuxRender forums (check the section dedicated to GPU acceleration).

SmallLuxGPU 2.0 renderer is 100% written in OpenCL (http://www.khronos.org/opencl/).

Posso sapere che scheda video hai? Dovrei acquistare un portatile che supporti le gpu e ho paura di fare una scelta sbagliata, avresti qualche consiglio da darmi.

Ti ringrazio :)

@TheCavetto Il video e' stato registrato su PC con 2xHD5870 + HD5850

is it possible to set an end time or it will just keep rendering forever? would be useful for rendering animation if there is an end time. nevertheless this is awesome!

[Dade916]

@leezhieng you can set a cap to the number of samples per pixel or to the total rendering time.

[Thet3]

@Dade916 so OpenCL is like Nvidia's Cuda but open to any gpu?

[Dade916]

@Thet3 Yes, exactly, it is like CUDA but it is an open standard endorsed by Apple, Intel, AMD, NVIDIA, etc.

@Dade916 Io in questo momento ho un ATI Mobility Radeon HD 5650, è possibile installare il supporto per OpneCL? Riuscirei a far girare SmallLux?

Grazie ancora :)

@Thet3 OpenCL is processed on the GPU specifically, not specialized shaders(CUDA).

[Thet3]

@Dade916 I was wondering because I was reading an article saying AMD is betting everything on openCL.

I really wonder how this will benefit gaming more in the future. I wonder what would happen if a game was made using a lot of openCL. Would DX11 still be needed?

@Bloodhammer1967 That is your opinion, and an utterly useless comment to this video. If you want SLG for Maya, go contribute to the exporter and shut up.

@eveleenbr

Uhh AO, Specular light, reflections, refractions, caustics are all part of the render method: Unbiased Ray Tracing. Any natural light effect you can think of is what raytracing excels at, albeit with a little time, or in GPU rendering, alot less time. Try google it. Sure Textures will take some memory, but no need for all those effect maps.

For non rigid objects, I would presume you choose desired position in Blender, and render it in SLG, unless some SLG guys know more?

[Bloodhammer1967]

learn Maya. its a much better software.
