Re: CIE 171:2006

Hi, This is belonging report for Nvidia's iray: Validation of NVIDIA's Iray against CIE 171_20160217.zip Wouldn't it be nice to place an information like in this commercial raytracer on luxcorerender webpage? https://www.optis-world.com/Showcase/News-Release/Corporate-Information/A-world-first-SPEOS...

Re: CIE 171:2006

Hello all, Look like there is an error here 2.1 cm instead of 2.1mm radius : thanks for first notification. Unfortunatly its only a typo in the report and the blender setting is right. It should be 2,1cm. Never the less the main critical point is the calculation using an IES file... As soon as we've...

Re: CIE 171:2006

Hi, I've just finished my first attempt for the first (out of 12 or more) test cases. If my process is correct, there seems to be a serious issue with working with IES files. Please have a look into the attached documentation and the corresponding blend files. I'm happy for every oppinion and every ...

Re: Material/Texture rework in v2.3

Hi, My wish for materials/volume nodes would be a way to define them more physics based. Old lux was able to read spectral absorption curves for volume colour. Also refractive indices curves for dispersion were possible... How is about integration of physics based scattering models like (Heyney Gree...

Re: Swimming pool / Underwater / Caustics

Hi all, One more question from my side. You said SDS paths are impossible to render with BiDir... But is it really impossible or just hard to render? I'm wondering because the images look quite good, what are you missing? Physics based render is always connected to some patience... remembering older...

Re: CIE 171:2006

Hi, I bought the document, but I think I'm not allowed to share it. It mentions a range of test cases that should compare the calculated/simulated results with some analytical and measured values. Within the next days I'll gonna try to run through each of the tests with luxcorerender... Are you inte...

Yes, that's why I was hoping that someone knows about its content already.

CIE 171:2006

Hi,

Does anyone know about this CIE 171:2006?
It's a report that handles "Test cases to assess the accuracy of lighting computer programs".

Do you know how luxcorerender will fit into this?
Thanks.

Export of denoised light group layers

Hi

I'm working on BlendLuxCore.
Is there a way to save result images for each light group individually denoised?

In a perfect world this will be possible while rendering is still active, or the light group adjustment keeps alive after stopping the render.

Thank you.

Re: Handling of relative refractive indices

Hi, I'm not talking about small tiny surfaces. It's a plastic part that is made in 2 shot process. One shot is a clear polycarbonate and the second shot is a black acrylic... This part is later on illuminated (through the clear element) by few LED In real life the intermediate face of those two volu...
