Reducing noise from unbiased renderer

[Welti]

I got an interesting video-link which is showing how noise from unbiased renderer can be reduced amazingly: http://www.youtube.com/watch?v=Ee51bkOlbMw. What are you thinking about this? The whole test-scenes were rendered with luxrender what is also shown at the end of the video.

wow that was very cool, learn't alot from that video. Any feedback from the Octane Render team on this?

That's been posted here a year or so ago.
Would be fantastic to have this running on top of octane all on GPU, octane feeding this algorithm the specific pass information it needs and amplifying it, but would mean a two step process now. Hit render with a max samples setting to something low like 500, then kick in the cleanup process and let that run for a time limit like 1 minute and you can watch it work too.

Would be impressive, fantastic renders at significantly reduced total times.


While we can be pretty sure they know about it since it's been talked about on here before by us customers, who knows if they even like the idea, or will act on it even IF it is possible...

Well the PDF paper with all the details is located here - see TOG -PDF file.

if someone can write a small c++ program to run Octanes output images though that program then i think we are in buisness.

see algorithm 1 in that paper

The LuxRender developer team is already working on it and they recreated a few steps of the process but not all. So it is already possible .

Hm... Interesting!.. I'll think about it...

That would be nice . But i think it isn't that easy...

... of course it isn't this was already debated a few months ago, before octane had the info channels, but afaik there is at least one channel not yet available (random parameters). but i'm pretty sure we will see this sooner or later, as the advantage esp. for animation rendering is tremendous...

I just think that if Octane-team is very busy with current roadmap, and this filter is not in this roadmap so far, it may be easier for them just add this one info channel to info-kernel and let to plugin-developers to realize this algorythm inside plugins... And later just add it to engine...
Just my thoughts...

Jimstarr I agree,
interior animations really need this, even with 680's and their 1500 cuda cores coming out I think the majority of people will not be able to afford enough hardware to render out interior animations, noise free, within a clients timeframe.
