DOF extra & ALF effect 3/13 2015

[Oyama]

Oyama,
try to add thresholds & multipliers in the desired effect, I don't want to make it more complicate than it already was.

Okay. But you made it FAR more simple code-wise... and efficient.
Anyway, these are matter of 3 o/ 4 additional lines

Hey uhm I think I asked you for permissions to port your effects to numerous stuff already but better one time too much than one time too less. I'm working hard on MasterEffect for ReShade and since I combined all DOF shaders to use the same focusing etc (you basically just switch blurring and weighting algorithms, the rest is uniform like blur radius etc) I am struggling to find a proper bleed masking and yours happen to be way better than anything I can think of (mine uses dynamic branching and is slow as fuck because it forces loop to unroll) so I'd need to copy heavily from your code, is that OK? You're mentioned in the credits ofc.

EDIT: were you high when writing this? "// Gloable Varibles "

Okay.
and no, just got a little bit too excited when wrapping up the file, combined with bad Enblish.

Hi there.

I added / changed the following things in your great dof effect:
- a desaturation effect (controlled by the 'DES' parameters).
- optimized a bit in the tight loop in PS_DepthOfField: (CenterCoC + 1) * BS_Highlight; is constant throughout the loop, so I precalculated that and moved it outside the forloop.

The desaturation effect desaturates depth pixels, meaning the more depth, the more desaturated the pixels, so you can get even more emphasis on the sharp subject.

Parameters added:
- DES Mode: 0 is normal DoF, 1 is saturate to greyscale, 2 is saturate to DES Blend Color
- DES Blend Color: the color to blend with the greyscale pixels so you can desaturate to another color instead of b/w.
- DES Blend factor, the factor with which DES Blend Color is blended onto the b/w pixels.

I used the 3.14 update, if you have changes made to this file, I can update it for you.

Hi OtisInf, welcome.

I've actually notice your work a couple of days ago on another screenshot site when I was googling around trying to find any dof feedback.
I definitely love the idea, relating color effect to the blur amount.

Thanks for the optimization, it will surely be included in future update.

[OtisInf]

Cool! Glad it's of any use

Liking the DEF parameters - this is rather cool.

Mode 1:



Mode 2: with RGB 0,0,0



Already doing some neat stuff with it in game.

[wolfgrimdark]

Just one more cause I am having so much fun with it:



EDIT: 3 samples (note I am using GS Jyggalag which is a somewhat desaturated sepia preset to begin with)

DES mode 0 (no desat)



DES mode 1 (BW desat)



DES mode 2 (RGB black with a mix of 0.6)

I had a question and apologies if a bit ignorant as I am not a shader coder. The DES gray scale, mode 1, is it possible to have a cap on the amount of desaturation? You wrote, "The desaturation effect desaturates depth pixels, meaning the more depth, the more desaturated the pixels" but it tends to make things BW when doing most close ups. I was wondering if there is a way to either set a max (say no more then 50% desaturation) or some other method that would prevent the out of focus area going purely BW.

if(DES_Mode > 0)
{
// grey scale blurred pixels based on depth.
float greyscaleAverage = (res.r + res.g + res.b) / 3.0;
float4 desColor = float4(greyscaleAverage, greyscaleAverage, greyscaleAverage, res.a);
if(DES_Mode==2)
{
desColor = lerp(desColor, float4(DES_BlendColor, res.a), DES_BlendFactor);
}
res = lerp(res, desColor, res.a);
}

I looked at the function but while I understand basic program flow I am not familiar with the functions or color processing. I could also just be missing something obvious to do this but thought I would ask at least.

[kingeric1992]

in the last line:

Code: Select all

res = lerp(res, desColor, staturate(res.a * DES_Level));

add this at the UI part

Code: Select all

float DES_Level = <string UIName="DES Level";   float UIMin=0.0;  float UIMax=100;  float UIStep=0.001; > = {0}; 

you can also read res.a in enbeffect.fx and mix it with prod's coloring effects.
