I am starting to work on it, but it won't be ready for 2.2

BlendLuxCore now supports the new adaptive sampling: http://forums.luxcorerender.org/viewtopic.php?f=5&t=1017&start=100#p12284 It is enabled by default if the sobol or random samplers are used. I was thinking about it and I guess that the adaptive sampling will behave a bit differently on B...

It is not. Is the emission comparable between them?

Which tonemapper are you using?

I wrote a c# white balance program several years ago for a friend that worked pretty flawlessly for her needs. I don't currently have a lux dev environment setup, but I could hack together a c++ version of an image pipeline in a text editor if someone wants to handle the opencl port when I'm done a...

If memory usage is the issue, you should use less threads for compiling. I don't know how to set that on Windows, but it shouldn't be too hard

If someone that would like to tackle this but is more comfortable with doing it using a web interface, I would be willing to write a webserver to work as the backend for this.

So, I've first seen the issue with this scene (100 samples in both case, warmup and test step is 5 with adaptivity): Would you be able to redo this test? Besides, keep in mind that the tonemap you choose is considered during the noise estimation, so rendering with some given tonemap settings and ch...

Comparing with the initial results, it seems this was an issue all along:

Fixed distribution: Wrong distribution: Uniform sampling:

Ok, so you have just draw the random numbers even if you are skipping the pixel :idea: This should be fix the problem at a trivial cost of generating just 3 more random numbers. Thanks for the suggestion! I just implemented and I think it is working as expected now. I will send the PR. This probabl...

Hello, I think I've found the issue. Currently, the seed for the RNG is based on the seedBase, that is a fixed value, and on the pixelIndex inside SobolSharedSampler. The pixelIndex is incremented by SOBOL_THREAD_WORK_SIZE every time the GetNewPixelIndex is called. This means that several seeds are ...
