Re: Blue noise dithered Sobol

The improvement is only for very low sample counts. I can see that the pattern is a bit more pleasing, but it is not a huuuge deal. I actually made the newer paper method work: (Besides having the blue-noise properties it also uses Owen-scrambled Sobol points, so it should have somewhat better conve...

Re: Blue noise dithered Sobol

Not yet, but the reports from Cycles is that blue noise improves denoise performance.
I will check it

Blue noise dithered Sobol

Hi, I have been investigating this topic lately and wanted to discuss if we have some reasonable way to implement that. 1st idea: I basically stole Cycles implementation (https://developer.blender.org/D2149) The idea is basically to use a blue noise mask to offset the samples between pixels. Instead...

Re: New OpenCL textures and materials evaluation code

Sounds great =)

I have a RX 580 + Ryzen 3600 and can test on Windows (I and Linux OpenCL drivers share a mutual hate for each other).
Will compile it as soon as a stop in front of the computer

I have reworked a bit triplanar texture code and now it works as I expect
Thanks for the help!

Re: Triplanar mapping / stochastic texturing

Sorry, I have been super busy lately and couldn't work on that.

I was hoping to have it done by the end of the year, but I have to merge the Multi UV changes into my triplanar branch.

I'll make an effort to have this done soon

Re: Image pipeline for Luxcoreui

As long as you don't use filmic, everything should match.

Can't you create an extra image pipeline to export the result in HDR (exr file format) and then post process it in Blender using filmic?

Re: Adaptive sampling improvements

Doesn't setting the adaptive strength to a lower value achieve the same pretty much; If its 0.7 then are 30% just sampled across the image and 70% use the adaptive map? Yes it would more or less. As future reference, here it is the complete flow with some small steps ommited: During ( warmup + step...

Great work!

I was keeping up with the commits and it was a big rabbit hole indeed :lol:

Re: Adaptive sampling improvements

to me this looks like noise is picked up ok, but there are areas that are not noisy, but more like almost not even sampled/completely black. I don't what setting you were using for step size and warmup but what is happening is that the metric is considering that after ( warmup+step ) samples, this ...
