Add bloom based on dual filter blur (#367)
* Update CRT-1tap to v1.2 * update default param * Update default param * Add bloom based on dual filter blur Previously squashed commits: WIP:Dual filtering bloom effect Add scale level weighting; Comment out debug code; Simplify tonemap Debug:Show bloom contrib Tweak defaults; Small bugfixes Organize shaders into subfolder Refactor tonemap into separate file Tweak parameters Greatly simplify exposure to intensity mapping; Clean up Fix faster preset Change luma pass size to 1 pixel Lots of polishing Add combined presets Add docs; Refactor params a bit; Cleanup Update combined presets Rename presets for better ordering

Dual Filter Blur & Bloom v1.1 by fishku

|

The dual filter blur implementation follows the notes of the SIGGRAPH 2015 talk here:
|
||||||
|
https://community.arm.com/cfs-file/__key/communityserver-blogs-components-weblogfiles/00-00-00-20-66/siggraph2015_2D00_mmg_2D00_marius_2D00_notes.pdf
|
||||||
|
Dual filtering is a fast large-radius blur that approximates a Gaussian blur. It is closely
|
||||||
|
related to the popular blur filter by Kawase, but runs faster at equal quality.
|
||||||
|
|
||||||
|
How it works: Any number of downsampling passes are chained with the same number of upsampling
|
||||||
|
passes in an hourglass configuration. Both types of resampling passes exploit bilinear
|
||||||
|
interpolation with carefully chosen coordinates and weights to produce a smooth output.
|
||||||
|
There are just 5 + 8 = 13 texture samples per combined down- and upsampling pass.
|
||||||
|
The effective blur radius increases with the number of passes.
|
||||||
|
|
||||||
|
This implementation adds a configurable blur strength which can diminish or accentuate the
|
||||||
|
effect compared to the reference implementation, equivalent to strength 1.0.
|
||||||
|
A blur strength above 3.0 may lead to artifacts, especially on presets with fewer passes.
|
||||||
|
|
||||||
|
The bloom filter applies a thresholding operation, then blurs the input to varying degrees.
|
||||||
|
The scene luminance is estimated using a feedback pass with variable update speed.
|
||||||
|
The final pass screen blends a tonemapped bloom value with the original input, with the bloom
|
||||||
|
intensity controlled by the scene luminance (a.k.a. eye adaption).
|
||||||
|
|
||||||
|
Changelog:
|
||||||
|
v1.1: Added bloom functionality.
|
||||||
|
v1.0: Initial release.
