Bluse-noise Dithered Sampling
 
Hi,

I am not much the technichel guy, but this looks very promising and intersting.

Could CentiLeo benefit from this?

I have read, that Corona is working on that at the moment and that will let the images look less noisy.

Very interesting stuff!

It can be a great addition, it's in the plans for the time of OptiX denoiser integration. I haven't read all the details yet, but as far as I know such a thing works for early samples. So, it can improve the visual noise impression for the 1spp, 4spp, 64spp. Just for low sample count. For high spp final frames it doesn't make any advantage (if I remember correctly).
But still it can be usefull for immeiate IPR previews + OptiX denoiser. People reported it improves denoiser for low spp.

Btw there is more recent achievment by Eric Heitz https://eheitzresearch.wordpress.com/762-2/
Jacco Bikker did it for his Lighthouse 2 path tracer project (real-time): https://twitter.com/j_bikker

Cycles did that tech you cited btw. But I don't remember how it worked for them in practice.

Yes, that should be right and as you said, that would be very useful for preview renderings in the IPR.
