Denoiser

[VISUALMAN_TOKYO]

Hi, it seems to be an hot topic recently, I wonder if you are considering integrating some kind of denoise algorhythm on the final rendered image. The most recent renderman version comes with it, I personally used it in a couple of occasions (in nuke) and is quite an efficient method, but I wonder if having it integrated in vray would make the process of rendering noise free much easier.

We won't be developing our own denoiser as it is a complex topic and we have zero experience with it. It's also riddled with patents already. But it may be possible that we partner with someone else to bundle a denoiser. We'll see...

Best regards,

This would be an amazing addition to vray if not the best,
The denoiser in Pixar Renderman 20 is one of the best advances in rendering to date, I have tested it myself and I must say that it does what it says on the tin, reduces render times by 2 - 10 times.

So what I suggest is to buy out Pixar ( Might involve buying out Disney) and then take their denoiser algorithm and then resell them again.

I expect to see The Denoiser feature in the next nightlies.

Thanks.

buy out pixar or disney good one.

yep!! denoiser tech from pixar on renderman its WOOOW!

[super gnu]

ha.. i was all ready to write a snobby post about how denoising always causes more problems than it solves, and keep it away from the renderer. then i looked up the renderman denoiser.

holy crap thats impressive.

impressive enough that im guessing every renderer will have a similar system soon, with the attendant speedups.

heres hoping vray is one of the first!

So what would you say about these? They are V-Ray renders processed by a denoiser called Altus developed by a company called InnoBright that we've been in touch with.

And a couple of more.

These are a couple of tests that I thought would trip the denoiser up because of the very fine details, but actually it did a very good job.

Vlado, Yes, Yes a thousand times yes.

This looks absolutely fantastic, you and your team are always on the ball it's just amazing.

I will be keeping my eye on InnoBright.

yep that looks "acceptable"

how does their system handle animation? i notice the pixar one uses temporal interpolation to allow it to work well with animation.

editk i checked their website. tempral filtering is supported. plus you lucky maya guys can download the beta version for free!!


i notice in their video test the temporal filter isnt as impressive as the spatial..some low frequency noise visible. but maybe it just needs a few more samples. worth checking that side thoroughly.



i will have all my fingers crossed that whatever discussions you are having would involve 3dsmax too.

As far as I know, Altus has the ability to denoise across frames (at least that's what they said in their Siggraph talk). There's some old video on their website that doesn't look too bad, I hope to see some more meaningful tests soon.

I feel a strong breeze will be blowing on those hair soon...
Stills look a LOT better than the last batch, artifacts all but gone: quite the clever job indeed.
I'm very curious as to the temporal stability on such fine detail...

[RotemS]

These do look very impressive, we see a very good SNR on all of them - there is virtually no damage to the structural details. It would be interesting to see a comparison between the denoised render and a reference high quality render.

Do they only take the RGB image as input?

[viscorbel]

Looks quite promising!
Hopefully it works out
