In Topic: Conversion Between std::string and std::wstring

Thanks for the explanation. I've edited the note to be a bit less wrong :).


In Topic: Faulty D3DCOMPILE_SKIP_OPTIMIZATION

Yes, of course :). Max is the most efficient solution here.

Hm, I think I've just solved the puzzle, to some extent. The value that are displayed differently, depending on the version, are NaNs, so apparently if's and max treat them differently, hence the difference in result.


In Topic: DoF - near field bleeding

Hm, I think the key here was:

near.a = saturate(near.a); // you can multiply by some value to avoid the "soft focus" effect at low CoC values

My first image that I managed to get was this:

After doing:

near.a = saturate(2.0 * near.a)

I got this:

But to be honest I still kind of prefer my old approach even though it's less correct :P. I actually have some small ideas on how to improve my first demo so I hope to have another demo with both solutions and be able to switch between one and the other.

Sorry for bothering you again but I decided to try Sousa's original approach and have difficulties once more. Which is strange because I'm pretty sure that when I was experimenting back when we were posting here I thought I had this working.

Nevertheless, I simply have problems with applying the near field over my sharp image. Here is a picture of my near field render target:

Here's the sharp picture:

And finally the sharp picture mul'ed by (1-cocNear):

I suppose I should somehow blend the first picture onto the third picture but no matter I do I get very poor results.
