--- Comment #7 from David Edmundson <k...@davidedmundson.co.uk> --- Git commit c193efc96239f1a0611206708b84dba2d7befdaa by David Edmundson, on behalf of Tatsuyuki Ishi. Committed on 01/09/2021 at 21:42. Pushed by davidedmundson into branch 'master'. blur: add noise in perceptual space The previous implementation added noise in linear space, which resulted in the effect becoming more pronounced on black backgrounds. This patch changes the process to be applied in perceptual space, by making the noise addition pass a separate draw call and disabling GL_FRAMEBUFFER_SRGB during that. After this change, noise will look much more suppressed and almost never grainy. This change also changes the range of the noise from [-strength..strength) to [0..strength), as blending can only be either additive or subtractive. As a result, users might need to ramp up their noise parameter after this change. v2: Add more explanation around the draw call. v3: Fix noise not fading out with the fade out effect. v4: Restore an accidentally removed comment. v5: Add CCBUG. v6: Rebase. v7: Fix a formatting issue.
