Re: Path Space Regularization (aka the solution to SDS paths)

It's sad, but understandable...

Does it mean the replacing of Hybrid rendering too?

Re: Path Space Regularization (aka the solution to SDS paths)

A forum thread from 2013 where one of the authors of the PSR paper answered some questions: https://ompf2.com/viewtopic.php?t=1743 Maybe my question is whether directional blur has some good properties for the combination with MCMC which spatial blur does not have. Yes, that is a very good question....

Re: Path Space Regularization (aka the solution to SDS paths)

Oh, I see, Dade has written OpenCL implementations from smallpt!

It is a SmallPT variant with direct light sampling, not the original one you are using :idea:
You're right, I just realised it, and edited my post.

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. If I render the same scene with the original smallpt (without PSR), I get a black frame with a few fireflies. EDIT...

Re: Path Space Regularization (aka the solution to SDS paths)

And in the SM there is a 65536 samples per pixel image of this scene.

Is this metropolis? Doesn't look like.

Re: Path Space Regularization (aka the solution to SDS paths)

Did you examine their sample implementation?

I have too little knowledge for this, unfortunately.

It is very generic and unclear.
I agree.

Re: Path Space Regularization (aka the solution to SDS paths)

I think the paper says about the same what I wrote, just a little vaguely worded: Our proposed method combines the simulated annealing optimization method with MCMC integration. Intuitively, the “sharp peaks” of the integrand are regularized (smoothed out) in the beginning of the integration such th...
