[Shader] FullScreen Smoothing + Scanlines

[shinra358]

I don't know if something like this has already been made or not but this is a fullscreen smoothing filter with scanlines shader (similar to that of which is on EPSXE with Pete's Opengl 2.9 plugin) that I made. The fullscreen smoothing, scanline thickness, and scanline opacity can all be edited individually to suit each person's resolution/taste. Edited meaning the ability to turn one or the other off/on and the smoothing intensity level, scanline thickness level, and scanline opacity levels.

*****Best if used with a 1920x1080 fullscreen resolution under the 'Graphics' > 'General' tab.*****

Optimal settings for the 1920x1080 fullscreen resolution include:

*
float smoothing_size = 1.0
float vPos = uv0.y*resolution.y / 2
float line_intensity = (((vPos - floor(vPos)) * 9) - 4) / 50

(light smoothing and light scanlines)



-or-



*
float smoothing_size = 1.0
float vPos = uv0.y*resolution.y / 3
float line_intensity = (((vPos - floor(vPos)) * 9) - 4) / 50

(light smoothing and med/light scanlines)



Here are some screenshots with a few combinations in 1920x1080 internal dolphin resolution:

Nice effect, I will try these shaders sometime tomorrow.

[Starscream]

Personally I wouldn't use this. I like how clear of an image Dolphin can provide at high internal resolutions, I wouldn't want to blur that look or have scanlines on the screen.

[delroth]

Then you're not the target and I don't even know why you're commenting.

delroth: I hope that your goal isn't to eradicate all thoughts and opinions that don't agree with yours. You don't have to agree with everything people say, you don't even have to like what they say, but that doesn't mean they're not allowed to say it. Of course, comments do have to be reasonable, which mine definitely was.

[shinra358]

@Starscream:

1. Your comment torward Delroth would mean you would be censoring him like you say you don't want to be 'censored'.
2. If you don't like it, then that means you didn't download it. Which also means what was the purpose of you commenting at all about it? Obviously to try to convince others as if they don't know what they like or not themselves.
3. If you don't like your pic smoothed, then you wouldn't have bought the wii console in the first place. When you play a game on a real wii, the picture is smoothed because it is not high res. It doesn't have pixelation at all or either tolerable pixelation due to smoothing. I'm assuming that since you are a part of this community, that you have or had a wii at one point or still.
4. There are a lack of shaders as it is. Why are you trying to 'censor' me considering you don't like it being done to you?
5. Thread is about a shader. Not about questioning others about an unrelated issue.
6. RE3 pic 1 is better than the others? Srsly? @.*
7. Let's just move along. We don't need to focus on what you are focusing on because that is not the thread's purpose. I know that there's not really that much to talk about but still. Jus' sayin'.



@dEnigma:

I hope that you enjoy them.


Peace. Keep up the good work on the emulator

How in the world did you come to that conclusion? I told delroth that people have the right to give their opinion.

Did you not post pictures for people to look at and comment on? My opinion was that they were blurry and that I wouldn't want my game to look that way. There's nothing wrong with that comment unless the original poster is overly sensitive.

Alright, now you're being ridiculous. My comment was about my opinion and my opinion alone.

You're right, that's why I didn't buy one.

Wow, what has the world come to. I gave my opinion and said that I personally wouldn't use this. I didn't tell you or anyone else that they don't have the right to give their opinion or like this. If I was working on something and someone didn't particularly like whatever it was that I was doing, I'd be fine as long as they gave their opinion in a respectful way. You're just plain unable to accept any comment that wasn't someone absolutely loving it.

I am commenting about your shader, what are you talking about?

I'm sorry that you're offended and were unable to accept my comment. I don't feel that I was out of line by simply stating that I wouldn't use this after looking at your screenshots. You posted screenshots for that exact purpose, so that people can see what you've done and then comment on it.

Other than that, continue to work on Dolphin, but you can't get all bent out of shape if someone happens to say that they wouldn't use your work. I've had that exact thing happen to me a number of times with Half-Life 2 projects I've done, it's just something that comes with the territory when you work on something and then make it public. It's nothing personal unless the person goes out of their way to insult you. That didn't happen in this case.

[NaturalViolence]

I.....I actually find myself agreeing with SS on this one. What has the world come to?

[dEnigma]

Wow, that escalated quickly^^

I agree with SS, he has every right to state his opinion as long as he isn't insulting anyone, which he clearly didn't.

b2t: I would love a shader similar to this: http://filthypants.blogspot.co.at/2013/02/designing-large-scale-phosphor.html

Would be like playing on an old CRT (well, almost). Not that I ever played Wii on an old CRT, but I played my SNES and N64 on one and sometimes I get these nostalgic feelings

edit: Or something like that would be fun too: http://filthypants.blogspot.co.at/2012/09/background-shader-for-retroarch.html

shinra358: Don't care about Starscream's and Delroth's conflict, it isn't because of you.

To the shader itself:
I don't like the way you've implement the smooth as you're using this window filter:
1 1 1
1 0 1
1 1 1

This one passes low and high frequencys, but the middle ones are blocked.

First, smooth usually is a lowpass, so a easy one would be:
1 2 1
2 4 2
1 2 1

Here you need a lowpass filter not to loose the information darked out on the scanline, so only in the y-achse direction:
0 1 0
0 2 0
0 1 0

Even better would be to use different one where in the scanline you are (written in lines):
on black line: 0 0 0 (just dark)
after black line: 1 2 0 (read third from the black line)
before black line: 0 2 1


Please don't feel rejected, I like your shader, but I think it still can be improved. If you want a better explanation, join us on #dolphin-emu on FreeNode.

dEnigma:
Just implement this shaders. It shouldn't be as hard as discribed there. And I don't think two passes would speed up (much), so this can be implemented easyly in dolphin.

btw: If anyone needs some additional inputs in postprocessing like frame counter or access to last framebuffers (eg for motion blur), just ping me
