SMAA for unity (subpixel morphological aliasing)

Hey everybody!
Based on http://www.iryoku.com/smaa/, i've made an implementation of this feature for unity. It works okay, just wanted to get your opinion. Still some work to be done (like stencil optimization), but this version is testible

https://github.com/m10914/SMAA-Unity

Waiting for your commentaries, guys!

 

Nice one! I tried to port it myself, but I kept getting wrong results.

So, thanks! I'll test it out later.

 

will test it some later, thanks)

 

some problems with shader - some errors in compile of shader and it looks like this

 

I am getting errors too but am excited to see it working!

 

I'd like to fix everything for your case, if you just send it to me!
It worked fine for me on test cases, what could possibly go so wrong?)

 

can you sent your test scene?
problems with compiling of shaders i show at screenshot, maybe console show other errors, i dont remember.
and i use Unity 4.2.0 pro version. tryed dx9 and dx11 rendering.

 

Any news on this? I get the same result as CTPEJIOK22 . Not working.

 

its a pity. i checked console output - only two errors about 94 line and 725, as at screenshot.
i found ine solution - using smaa injector, sometimes it work. http://mrhaandi.blogspot.ru/p/injectsmaa.html
but its interesting to see smaa shader directly in unity

 

same error as CTPEJIOK22 ..

 

CTPEJIOK22, Strange. I have it shows:

Unity v. 4.2.1f4.

But script still does not work properly. If I switch the state=3 little effect visible on the foliage of trees.

 

Didn't you forget to set a few textures over there? I know Area and Search tex are included with SMAA source on their page, but I'm not sure about the others

 

heh) maybe its a key. downloaded 2 textures, will test others.

 

Guys, areatex and searchtex are generated programatically in AreaTex and SearchTex classes!!! no need to download anything!!! =)

I added to git my own test scene, in which there's only a sphere (+properly configured effect). It should work properly, as i think.
There was another one, clone of smaa's DirectX demo sample, if you'd like that, i can add it too.

I noticed looking through the shader:

I switched the camera to 1280x720 and then shader works!



But shader is dependent on the resolution

In any case, thanks damonwall!
I have the idea as it can be solved.

 

Evilfox, let me have a look at it..

@ Damon, thanks for this you have saved me a lot of work.. If you don't mind, I want to do a cmaa / smaa hybrid.. For our project, then I will release it to the Public.. Free of charge, of course:

http://software.intel.com/en-us/articles/conservative-morphological-anti-aliasing-cmaa

 

Code (csharp):

1. #define SMAA_RT_METRICS float4(1.0 / _ScreenParams.x, 1.0 / _ScreenParams.y, _ScreenParams.x, _ScreenParams.y)

 

Thanks! Much easier than I thought.

 

A-a-ah, here's the explanation, why this shader worked fine on my computer, but it didn't on others =) Pixel-perfect algorythm, huh =) Thanks much!
I've made a fixed version, based on your fork. Thank you, i hope now someone will find it useful)

Btw, if someone interested, this version will be used in our game "VoidExpanse", details can be found here: http://atomictorch.com

 

Thanks a ton for this, this is far better than the AA solutions that come with Unity.

Thanks a lot

 

Hmm, just tried throwing this in my scene and weirdly it turns entirely black (with exception to the NGUI gui I have up). Does this conflict with HDR/Linear/Deferred? Have you tested this in Unity 4.3.3 by chance?

Thanks!

 

Works for me without problems. Need more details. State 3 must be set.

 

Derp, there we go. Setting State 3 made everything work. Looks wonderful. What's the perf cost of this compared to FXAA roughly? I really like what it does.

 

Hey this is awesome! Everything works, but when I try to build the game, it give 2 errors
,

Please help

PS : Unity v4.3.2

The project builds, but when I run the .exe file, I am left with a grey screen. Nothing shows up, except the Unity logo at the start.

 

thank you)

 

Hello, I'm using MSAA together with SMAA(from here: https://github.com/Chman/uSMAA ) and I have the flip problem, could someone give some details on how to fix it? I've tried editing SMAA shader from the link above but I always got errors since I'm not much into coding shaders.

I've tried putting this in all vertOUT vertex:

#if UNITY_UV_STARTS_AT_TOP
OUT.offset1.xy = IN.texcoord;
if (_MainTex_TexelSize.y < 0)
OUT.offset1.y = 1-OUT.offset1.y;
#endif

 

@Simon_says: why would you use two AA solutions together?! that sounds like overkill...

 

SMAA for unity is that supported also on Mobile Devices?

 

How do you enable super sampling?
