//
//  Modifications to this file done by Unity for use with the Universal RP:
//    * Added the middle pixel's color as a parameter to the FXAA fragment function
//      for both the 'FXAA_PC == 1' and 'FXAA_PC_CONSOLE == 1' variants
//      (to avoid resampling it during FXAA as we already have it by then)
//    * Changed the 'FXAA_GREEN_AS_LUMA == 0' code-path to compute Luma from sRGB
//      (as we don't pre-store luma in the w component of the input texture)
//    * Changed the FxaaTex* defines to use URP's platform agnostic sampling macros
//    * Removed PS3 "#pragma" directives as they are irrelevant for us and were causing warnings

                    NVIDIA FXAA 3.11 by TIMOTHY LOTTES

------------------------------------------------------------------------------
                           INTEGRATION CHECKLIST
------------------------------------------------------------------------------
(1.)
In the shader source, setup defines for the desired configuration.
When providing multiple shaders (for different presets),
simply setup the defines differently in multiple files.
Example,

  #define FXAA_PC 1
  #define FXAA_HLSL_5 1
  #define FXAA_QUALITY__PRESET 12

Or,

  #define FXAA_360 1

Or,

  #define FXAA_PS3 1

Etc.

(2.)
Then include this file,

  #include "Fxaa3_11.h"

(3.)
Then call the FXAA pixel shader from within your desired shader.
Look at the FXAA Quality FxaaPixelShader() for docs on inputs.
As for FXAA 3.11 all inputs for all shaders are the same
to enable easy porting between platforms.

  return FxaaPixelShader(...);

(4.)
Insure pass prior to FXAA outputs RGBL (see next section).
Or use,

  #define FXAA_GREEN_AS_LUMA 1

(5.)
Setup engine to provide the following constants
which are used in the FxaaPixelShader() inputs,

  FxaaFloat2 fxaaQualityRcpFrame,
  FxaaFloat4 fxaaConsoleRcpFrameOpt,
  FxaaFloat4 fxaaConsoleRcpFrameOpt2,
  FxaaFloat4 fxaaConsole360RcpFrameOpt2,
  FxaaFloat fxaaQualitySubpix,
  FxaaFloat fxaaQualityEdgeThreshold,
  FxaaFloat fxaaQualityEdgeThresholdMin,
  FxaaFloat fxaaConsoleEdgeSharpness,
  FxaaFloat fxaaConsoleEdgeThreshold,
  FxaaFloat fxaaConsoleEdgeThresholdMin,
  FxaaFloat4 fxaaConsole360ConstDir

Look at the FXAA Quality FxaaPixelShader() for docs on inputs.

(6.)
Have FXAA vertex shader run as a full screen triangle,
and output "pos" and "fxaaConsolePosPos"
such that inputs in the pixel shader provide,

  // {xy} = center of pixel
  FxaaFloat2 pos,

  // {xy__} = upper left of pixel
  // {__zw} = lower right of pixel
  FxaaFloat4 fxaaConsolePosPos,

(7.)
Insure the texture sampler(s) used by FXAA are set to bilinear filtering.


------------------------------------------------------------------------------
                    INTEGRATION - RGBL AND COLORSPACE
------------------------------------------------------------------------------
FXAA3 requires RGBL as input unless the following is set,

  #define FXAA_GREEN_AS_LUMA 1

In which case the engine uses green in place of luma,
and requires RGB input is in a non-linear colorspace.

RGB should be LDR (low dynamic range).
Specifically do FXAA after tonemapping.

RGB data as returned by a texture fetch can be non-linear,
or linear when FXAA_GREEN_AS_LUMA is not set.
Note an "sRGB format" texture counts as linear,
because the result of a texture fetch is linear data.
Regular "RGBA8" textures in the sRGB colorspace are non-linear.

If FXAA_GREEN_AS_LUMA is not set,
luma must be stored in the alpha channel prior to running FXAA.
This luma should be in a perceptual space (could be gamma 2.0).
Example pass before FXAA where output is gamma 2.0 encoded,

  color.rgb = ToneMap(color.rgb); // linear color output
  color.rgb = sqrt(color.rgb);    // gamma 2.0 color output
  return color;

To use FXAA,

  color.rgb = ToneMap(color.rgb);  // linear color output
  color.rgb = sqrt(color.rgb);     // gamma 2.0 color output
  color.a = dot(color.rgb, FxaaFloat3(0.299, 0.587, 0.114)); // compute luma
  return color;

Another example where output is linear encoded,
say for instance writing to an sRGB formated render target,
where the render target does the conversion back to sRGB after blending,

  color.rgb = ToneMap(color.rgb); // linear color output
  return color;

To use FXAA,

  color.rgb = ToneMap(color.rgb); // linear color output
  color.a = sqrt(dot(color.rgb, FxaaFloat3(0.299, 0.587, 0.114))); // compute luma
  return color;

Getting luma correct is required for the algorithm to work correctly.


------------------------------------------------------------------------------
                          BEING LINEARLY CORRECT?
------------------------------------------------------------------------------
Applying FXAA to a framebuffer with linear RGB color will look worse.
This is very counter intuitive, but happends to be true in this case.
The reason is because dithering artifacts will be more visiable
in a linear colorspace.


------------------------------------------------------------------------------
                             COMPLEX INTEGRATION
------------------------------------------------------------------------------
Q. What if the engine is blending into RGB before wanting to run FXAA?

A. In the last opaque pass prior to FXAA,
   have the pass write out luma into alpha.
   Then blend into RGB only.
   FXAA should be able to run ok
   assuming the blending pass did not any add aliasing.
   This should be the common case for particles and common blending passes.

A. Or use FXAA_GREEN_AS_LUMA.

Either are higher qualilty and almost as fast as this on modern PC GPUs.

------------------------------------------------------------------------------
This optimized version thanks to suggestions from Andy Luedke.
Should be fully tex bound in all cases.
As of the FXAA 3.11 release, I have still not tested this code,
however I fixed a bug which was in both FXAA 3.9 and FXAA 3.10.
And note this is replacing the old unoptimized version.
If it does not work, please let me know so I can fix it.

         FXAA3 CONSOLE - OPTIMIZED PS3 PIXEL SHADER (NO EARLY EXIT)

==============================================================================
The code below does not exactly match the assembly.
I have a feeling that 12 cycles is possible, but was not able to get there.
Might have to increase register count to get full performance.
Note this shader does not use perspective interpolation.

Use the following cgc options,

  --fenable-bx2 --fastmath --fastprecision --nofloatbindings

       FXAA3 CONSOLE - OPTIMIZED PS3 PIXEL SHADER (WITH EARLY EXIT)

==============================================================================
The code mostly matches the assembly.
I have a feeling that 14 cycles is possible, but was not able to get there.
Might have to increase register count to get full performance.
Note this shader does not use perspective interpolation.

Use the following cgc options,

 --fenable-bx2 --fastmath --fastprecision --nofloatbindings

Use of FXAA_GREEN_AS_LUMA currently adds a cycle (16 clks).
Will look at fixing this for FXAA 3.12.
