Re: Quasirandom sampler
Now you have to establish if it is of any use :mrgreen: Does it converge faster than Sobol sampler (i.e. less noise in the same amount of samples) ? P.S. people will endless complain about patterns at the start but it may be still of some use if it is noticeably better than Sobol. I still think the...

Re: Quasirandom sampler
I think it is converging to the right solution now. It also helps when you don't calculate the same constant every time =p

Re: Quasirandom sampler
Things are looking better, but there are plenty of visible patterns indeed for now.

Re: Quasirandom sampler
I had understood that it would be called every time the samples would be calculated and subsequent calls for GetSample would always return the same result until a new RequestSample was called. I am reading the Sobol code to understand how it is done over there and it appears to me that what prevents...

Re: Quasirandom sampler
Hi, Thanks for the directions, I think I understand how it should work now. It is still not working and it seems that the RequestSamples method is called at the beginning and not called again, so the samples are always the same. I will have a look at this tomorrow. About something tangentially relat...

Re: CGI tech news box
Sure, it's here: https://github.com/Alpistinho/LuxCore on the r2_sampler branch.
To use the sampler just put R2 in the configuration file.

Re: CGI tech news box
Hi, As expected the result does not converge to the right output. So, I was investigating and I have at least a couple of questions about the Sampler interface: 1. The GetSample method can return 3 different values based on how it is called. If the index is 0 or 1, the value returned is sample0 or s...

Re: CGI tech news box
Have you tried to run the rendering for a very loooong time ? It may be just the samples correlation I was talking about. Plain Sobol, without shuffling looks similar. I will try that, but I am not confident. I was expecting the patterns to be more like this: https://www.shadertoy.com/view/4dtBWH B...

Re: Old reprositories or setups
The sketchup plugin is available at: https://bitbucket.org/luxrender/su2lux
You can download it and install on the plugins folder as it would be done with any other plugin installed directly from source. You could also go to he old forums and grab the release there: www.luxrender.net/forum
