[DX9 and DX11] Darken Distance

[--JawZ--]

This was done by request from jake_S.

It allows a darkening effect, that visually behaves similar to fog. But is not dependent on anything in-game.

You can alter the amount of darkening, or even brighten the distance up a bit. It is also possible to determine where the effect should start from, right from the player feet or at the bottom of the distant mountains.

v1.1: Corrected DX9 version, added a simple color tint to both versions.

Thanks a lot JawZ and all the best in the New Year

You're welcome Guzio

Thank you. The more unique effects, the better

Rather than darkening I'd have desaturation or color shift towards blue in the distance. OK now I see there's color tint option, maybe that'd work.

Sorry for the noob question, I really love the idea here, but I have no clue on how to make this work on my game; is there a tutorial for adding custom effects, or I just drop the files somewhere?

Hey guys,

Is there a way to implement a sort of gradient between the foreground to the distance? Say, for the instance, you can choose a foreground tint and then transition to the distance tint that is already implemented in the included code.

Thanks for the code and help!

Better make sample image in photo editor to understand what is background for you and how to apply it.

My "split tone" effect from ColorLab will basically let you do this, you just use depth instead of brightness for it.

Code: Select all

// step function to use for the split range effect
// possible options:
//   linearstep
//   smoothstep
#define SPLIT_RANGE_STEP_FUNCTION linearstep

float3 splitRanges(float t, float lo1, float lo2, float hi1, float hi2)
{
    float3 res;

    float2 lo = float2(lo1, lo2);
    float2 hi = float2(hi1, hi2);

    hi.x = 1.0 - hi.x;

    hi.y = clamp(hi.y, lo.x, hi.x-1e-6);
    lo.y = clamp(lo.y, lo.x+1e-6, hi.x);

    res.x = SPLIT_RANGE_STEP_FUNCTION(lo.y, lo.x, t);
    res.y = SPLIT_RANGE_STEP_FUNCTION(lo.x, lo.y, t) - SPLIT_RANGE_STEP_FUNCTION(hi.y, hi.x, t);
    res.z = SPLIT_RANGE_STEP_FUNCTION(hi.y, hi.x, t);

    return saturate(res);
}

/* Proposed usage for depth based effect:
    float linear_depth = getLinearDepth(); // Get it one way or another
    float3 split_weights = splitRanges(linear_depth, ForegroundDeadzone, ForegroundCutoff, BackgroundDeadzone, BackgroundCutoff);
    float3 tint = mul(split_weights, float3x3(ForegroundColor, MiddlegroundColor, BackgroundColor));
    color.xyz = lerp(color.xyz, color.xyz * tint, DepthEffectIntensity);
*/

/* Proposed usage for luma based effect:
    float luma = getLuma(color); // Your preferred luma function
    float3 split_weights = splitRanges(luma, ShadowsDeadzone, ShadowsCutoff, HighlightsDeadzone, HighlightsCutoff);
    float3 tint = mul(split_weights, float3x3(ShadowsColor, MidtonesColor, HighlightsColor));
    color.xyz = lerp(color.xyz, color.xyz * tint, SplitToneEffectIntensity);
*/

The Deadzone and Cutoff parameters should just be in the 0-1 range. You could look at ColorLab to see how the parameters work and how to set them up, if you enable graphs you can get a feel for it. I hope I didn't leave out too much details for using the code, if you need help using it let me know.
