"FXAA Rules, OK?"

FlaH would like to thank everyone for their hard work on this and the amazing results produced.



However, he is currently trying to find his lower jaw after it bounced off the desk so he is unable to tell you himself.



:stuck_out_tongue:



Cheers!

As i dont have commit access someone else should do this.



Thank you for your sharing!!!
@nehon , would you like to put this amazing code to JME CORE?

Of course I do :D

I think the GammaCorrectionFilter could be useful as a stand alone filter too.
Is it mandatory for using the new FXAA?
If it is, it should be rendered as a pre-pass yes.
I'm gonna look into it

I agree that itā€™d be nice to have it available externally. But if the gamma filter enhance the FXAA filter then I think there should be one embedded into it. AFAIK itā€™s better if itā€™s processed as an internal pass.



Of course thereā€™s always the risk of having some people thinking the gamma filter should be added (separately) before turning it on in the FXAAā€¦ I know, I know, but itā€™s possible. Iā€™ve seen worse. :wink:

25

I LOVE YOU GUYS!

26

@nehon , any chance to put this cool shader to JME beta?

27

Its in svn for quite some time nowā€¦

28

WOW!! COOOL!!!

Now everybody can test and use it!

http://code.google.com/p/jmonkeyengine/source/browse/trunk/sdk/jme3-core/src/com/jme3/gde/core/filters/impl/JmeFXAAFilter.java?r=8253



May I ask coredevs about Gamma Correction? I mean what @phate666 did aboveā€¦ Will it stay in JmeFXAAFilter or you make another one?

29

the thing is i tested the new version but got a big performance hit compared to the old one with a barely noticeable visual effect change, so i did not add it to the core.

But maybe i did something wrong.



Also the gamaCorection Filter could be useful on its own i guess iā€™ll add it

30

Possibly you should try the old version to compare fps?



About gamaCorection Filter is coool!!



Just give us feedback about it here when you add it to the core.

Done

I tried FXAA today and got a long error which i dont understand. (Using nightly build 11 11 2011)

your hardware does not support the GPU shader 4 extension.

I guess we should mention this in the javadoc of the filter

I think gpu shader 4 needs opengl 3 or even 3.2 support

1 Like
34

I see,

thank you nehon

35

@nehon: perhaps the GLSL language versions that are used in the material can be raised. This will make a proper error message be shown instead, what do you think?

36

I was thinking of checking the extension in the Filter, raise a warning and disable it when the extension is not found.

But yeah we can also raise the shader version

37

I prefer to rely on GLSL version for features ā€¦ Extension support is usually pretty bad and may have various bugs

38

oh ok, I didnā€™t know

Iā€™ll check what exactly is the glsl version for shader model 4, and change the j3m accordingly.

The thing isā€¦this is going to crash right?

for filters it could be nice to have a fallback.

39

Many filters just donā€™t have a fallback ā€¦ As far as I see it thereā€™s two options:

  1. Crash
  2. Do nothing



    But regardless of which option we choose, we could have a Filter.isSupported() or FilterPostProcessor.supportsFilter() method that could check if the current hardware can run the filter
40

Thatā€™s great man, thanks for staying on top of this. Iā€™ve been interested in in new stuff like this:

MIX MSAA + OGSSAA + FXAA 2xTSSAA

I saw an equivalent for this in the Trine 2 beta, specifically:
Medium (FXAA)
High (FXAA+2xSSAA)
Very High (FXAA+4xSSAA)

I'm sure a lot of interesting combinations can be made from this.
