I sort of think he doesn't necessarily ask for adaptivity, he asks about some direct information on "how" clear/noisy the image, as Laci wrote, a clue on passes :- )
He just wants some more exact way to estimate this. But I guess the threshold Deadclown write might be that.
thanks for helping to clarify my request guys
Yes, What I suggest is to have a VISIBLE INFO about how much noise or clear the image is, just in order to know WHEN I could stop the image, depending on my needs
if an image still noisy after 10 min, but info on screen says that is 50% "clear" I can wait 10 minutes more for a better one, just ir order to have a clue about redering times.
It would be use for batch rendering, instead asigning xxx hrs, or XXX passes to all images- which in most cases - are exceeding the needs, user can say: "ok for a 720x405 it may take 5 min for have a 99% "finished" render , and for 5000x3000 it would take 2 hours for a 95% clear image (since waiting for last 5% would be probably an excess, and almost a-not-noticeable quality).
what do you think?
