Re: Path Space Regularization (aka the solution to SDS paths)
It's worth noting, that the minimalistic PSR sample implementation (based on smallpt) uses a very small light source. It has 3300 times smaller radius than the mirror and glass spheres. Apparently, the initial r0=1 (as suggested by the paper) is a bit too small. These are 2048 and 16384 samples per...

Re: Path Space Regularization (aka the solution to SDS paths)
Is this metropolis? Doesn't look like. No it is regularised path tracing inspired by the code in the paper. My initial plan was first to understand smallpt with Path Space Regularization and then apply it to smallmmlt. But smallmmlt is above my poor understanding of all this stuff. They don't even ...

Re: Path Space Regularization (aka the solution to SDS paths)
They talk of "throughout the integration" or "mutation number" (without large or small qualifier). It is very generic and unclear. This statement is pretty clear to me as it comes from the field of many-body physics where the simulated annealing is used extensively. The general ...

Re: Path Space Regularization (aka the solution to SDS paths)
BTW, they aknowledge the probleem I'm talking about in their paper: Since the mollification angle can become very narrow after many iterations, it can run out of floating point precision. if the problem with machine precision appears in the angle r then it might be this place cosMax = 1.f / sqrtf(1...

Re: Mac OS
Hi, I tried to compile LuxCore in macOS and unsurprising got problems. First I checked that the old version of Luxrays compiles ok. Then I updated the necessary libraries from the blender-darwin and tried to compile the master branch of LuxCore. I used the Config_OSX.cmake published in this thread. ...
