Hi, I had some bug in the normals-calculation at edges, and think this was causing part of the error, even if I did not re-rerendered this scene yet. Another source of this kind of "halo" is in the AO-calculation, but also this algorithm was renewed. It is really fun to play with all of those things, and probably I will replace it a few times before it fits

Cheers!

I was referring to the dark halos around the outside of objects in different focus, and essentially it's because of something like this:

weighted_sum = 0
for (image region)
{
  if (some_condition) continue; // offscreen, diff depth regions, etc
  weighted_sum += pixel * weight
}
weighted_sum /= some_constant

and to fix it, you normalise the sum:

weighted_sum = 0
norm = 0
for (image region)
{
  if (some_condition) continue; // offscreen, diff depth regions, etc
  weighted_sum += pixel * weight
  norm += weight
}
weighted_sum /= norm

Hmmm, I see, usually I normalize it this way, but thanks anyway, will look at this later

Cheers!

Hi, thanks for the comment!
For me, the beauty of algorithms and rendered images are very different, but I love the beauty in both. Sometimes, there comes in one additional element: the beauty/simplicity in implementation, which is again different (for me)

Cheers!

Thanks! But, it is an early alpha version, it will take time to finish a release version
