[Bf-cycles] Interactive GI filtering paper

[Marco G]

Hi all,just stumbled upon this paper, i'd be curious to know what Cycles devs think about such technique,results seems quite accurate and unlike other filtering/reconstruction methods, it is done online interactively.

Would something like this be unusable, introducing a lot of inaccuracy? (or complexity to the code..?)Speaking more in general, isn't there any idea (for the future) to help/simplify diffuse-indirect calculation? (not Irradiance cache related, but something animation-friendly)
Thanks,regards.
