Temporal Anti-Aliasing

You should do a view to showcase the REAL benefits of temporal AA. also, some numbers to compare the performance of these to the FXAA and other solutions would be awesome.

 

Looks awesome, thank you for sharing!

Would TAA be useful for VR? In other words: Does it not impact performance too severely for typical VR games, and does it address the specific issues you're facing with non-AA'ed scenes in VR?

As flickering is one of the issues that's super-annoying in VR, it seems like TAA might be a perfect fit for VR. I'm just concerned about the performance hit.

 

Enabling Temporal (Experimental) makes me see vertically mirrored jittering ghosts of the scene objects.

 

Any plans to implement a project wide texture mip bias to handle the texture over blurring of TAA?

 

Must. Try. ASAP.

 

Great results, cheers !

 

I downloaded the repo from BitBucket and used the AntiAliasing script from CinematicEffects(ALPHA)/AntiAliasing. What am I doing wrong?

 

Whoops, thanks a lot!

Edit: Right, it seems downloading the repo just gives you the main branch, I guess I need to setup Mercurial.

 

Click on download, click on branches, click on "zip" next to taa

 

Turn out I'm very stupid, thanks!

 

Nah, it's just really confusing.

 

Hi,
I just have a simple question, is this working only with forward renderring or deferred is supported?

 

Are there some specific kinds of scene setups that TAA works best and worst with? I read the Bart Wrongski blog but I'm not sure how much of that applies and which parts specifically are problematic. It did mention having to customize lots of stuff for TAA, is that still the case, or should it be just something you slap in a scene and expect to work?

I tried TAA with a scene that has a lot of small, moving creeps with small limbs that are animated by changing the mesh manually (to avoid Mecanim overhead & use instancing) and the result wasn't good. I don't know if it's an inherently difficult use case for which it's better to use some other technique, or if it can be improved.

 

I gave it a quick go and deleted it. No options to tweaks, performs less better than the TAA made by LIMBO guys. But it's a bit better on moving objects though (probably because the use of motion buffer). I'll give it a new go once we get some options to tweak jitter parameters.

 

Sounds like you would possibly prefer to use MSAA?

 

TAA give me better antialiasing than anything else I've tried (better than MSAA and FXAA).
If i have control over temporal buffer and jitter parameters to tweak it would be a lot better than LIMBO guys TAA as the results on moving objects it's a lot better but current implementation jitter buffer it's unstable to my taste (that's why i need some params to tweak it).
[EDIT] I'll browse the sources and see if I can expose something and/or tweak the jitter buffer.

 

I'm guessing they haven't done a performance pass on any of the post really (maybe it still wants to be merged or something) - looks WIP to me but lovely results so far... perf is a worry indeed.

 

Didn't try it yet, but if the reason it's "slow" is that it generates the motion buffer, maybe the cost will be offset by other effects that need motion vectors (motion blur, any filter with temporal filtering)?

 

Hey Tim,
Yeah I'm downloading the version you just pushed and will see what I can change then let you know my suggestions about what what can be exposed.

 

Hi Tim, I'm on PS4 as well, so I need all I can get. Appreciate all your work, means a lot to me.

 

1.4 ms sounds pretty good. 2.8 ms, of course, is fairly intense. Can't wait for the days when everything will just work with single-pass stereo rendering ;-)

 

Would this have any application for 2d sprites or sprite tiling? The current AA method in unity brings out lines between tiles that shouldn't be there. Would TAA be any less susceptible to this?

 

Try it and let us know?

 

You shouldn't be needing AA with 2D. If you're mixing it with 3D then a better option is to render the 2D to texture I guess or use multiple cameras? Can MSAA be toggled between camera renders? never tried it.

 

Any plan on having options on it? On your example video, in most case, I would prefer it off since it gives a kind of blurriness to the whole scene, smudging the details in the texture.

And yes, 2+ ms is intensive for someone who aims at 60FPS on PS4.

 

It's at 1.4 ms right now. Which I think is reasonable for such a high quality AA.

 

It won't be the only cost though, bloom is a must along with tonemapping, grading and motion blur. So I'm hoping that further savings will come with them all combined. I probably will skip SSRR and AO and probably will skip DOF if it's too expensive too... Kind of want to keep all my post <3ms if possible.

That's just the AA, right? need to factor in the motion vectors cost as well. But since I absolutely must have motion blur, that at least gets used twice...

 

Which is why having some options to reduce the quality would be nice. We have ton of other post effect to factor in; bloom, lense flare, lense dirt, tonemap, AO.

SSRR is out of question for 60FPS, we learned that the hard way.

 

I think once they combine the post, the savings will be bigger, I wonder if there's a roadmap for cinematic effects?

 

Tested it out,I'm very happy that we're finally getting TAA in Unity. The current version is looking pretty decent.

 

Is there any way to get access to the TAA filter without going through bitbucket. I am not allowed to set this up on my PC.

 

You can get it from the asset store if you like. Should be updated by now. And what do you mean "not allowed to set this up" ? it's just a project you can download and copy over the folders...

 

People in a corporate setting aren't always allowed to change anything outside of their My Documents folder. This includes the Unity installation folder. I personally don't like doing it because I want a "clean" install of Unity at all times. Is there any actual way to build things from bitbucket and override them on a project-by-project basis? I tried with Unity Networking once and it just broke everything until I reinstalled.

 

The bit bucket site has a download link with a zip file that you just extract into your project's asset folder. Nothing should be going into the unity editor folder or requiring any special building. The only difference between the asset store version and the bit bucket version is the bit bucket version is a little newer and the asset store is packaged as an asset package.
