Magic Bloom by luluco250
|
||||||
|
Attempts to simulate a natural-looking bloom.
|
||||||
|
Features:
|
||||||
|
--Wide bloom blurring, derived from the gaussian function
|
||||||
|
defined here: https://en.wikipedia.org/wiki/Gaussian_blur#Mathematics
|
||||||
|
--Eye adaptation, decreases or increases the brightness
|
||||||
|
of bloom according to the overall image luminance.
|
||||||
|
--Lens dirt, as standard I suppose. Really not much here.
|
||||||
|
It uses an image named "MagicBloom_Dirt.png" so make
|
||||||
|
sure you have one in your textures directory.
|
||||||
|
--Unwanted features can be disabled through
|
||||||
|
preprocessor definitions, saving performance.
|
||||||
|
|
||||||
|
Preprocessor definitions:
|
||||||
|
--MAGICBLOOM_ADAPT_RESOLUTION:
|
||||||
|
Determines the width/height of the texture used for adaptation.
|
||||||
|
It is recommended to use 256, but you can use as far as 1024 without issues.
|
||||||
|
Too low resolutions will make adaptation seem "unstable".
|
||||||
|
Must be a power of two value: 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024 etc.
|
||||||
|
--MAGICBLOOM_BLUR_PRECALCULATED:
|
||||||
|
If set to 0 the gaussian blur will be calculated inside the shader.
|
||||||
|
Otherwise, it uses a pre-calculated kernel (array).
|
||||||
|
|
||||||
|
--MAGICBLOOM_NODIRT:
|
||||||
|
If set to 1 all lens dirt related features are disabled.
|
||||||
|
Beneficial for performance if you don't wish to use lens dirt.
|
||||||
|
--MAGICBLOOM_NOADAPT:
|
||||||
|
If set to 1 all adaptation related features are disabled.
|
||||||
|
Beneficial for performance if you don't wish to use adaptation.

Magic Bloom by luluco250
|
||||||
|
Attempts to simulate a natural-looking bloom.
|
||||||
|
Features:
|
||||||
|
--Wide bloom blurring, derived from the gaussian function
|
||||||
|
defined here: https://en.wikipedia.org/wiki/Gaussian_blur#Mathematics
|
||||||
|
--Eye adaptation, decreases or increases the brightness
|
||||||
|
of bloom according to the overall image luminance.
|
||||||
|
--Lens dirt, as standard I suppose. Really not much here.
|
||||||
|
It uses an image named "MagicBloom_Dirt.png" so make
|
||||||
|
sure you have one in your textures directory.
|
||||||
|
--Unwanted features can be disabled through
|
||||||
|
preprocessor definitions, saving performance.
|
||||||
|
|
||||||
|
Preprocessor definitions:
|
||||||
|
--MAGICBLOOM_ADAPT_RESOLUTION:
|
||||||
|
Determines the width/height of the texture used for adaptation.
|
||||||
|
It is recommended to use 256, but you can use as far as 1024 without issues.
|
||||||
|
Too low resolutions will make adaptation seem "unstable".
|
||||||
|
Must be a power of two value: 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024 etc.
|
||||||
|
--MAGICBLOOM_BLUR_PRECALCULATED:
|
||||||
|
If set to 0 the gaussian blur will be calculated inside the shader.
|
||||||
|
Otherwise, it uses a pre-calculated kernel (array).
|
||||||
|
|
||||||
|
--MAGICBLOOM_NODIRT:
|
||||||
|
If set to 1 all lens dirt related features are disabled.
|
||||||
|
Beneficial for performance if you don't wish to use lens dirt.
|
||||||
|
--MAGICBLOOM_NOADAPT:
|
||||||
|
If set to 1 all adaptation related features are disabled.
|
||||||
|
Beneficial for performance if you don't wish to use adaptation.

Magic Bloom by luluco250
|
||||||
|
Attempts to simulate a natural-looking bloom.
|
||||||
|
Features:
|
||||||
|
--Wide bloom blurring, derived from the gaussian function
|
||||||
|
defined here: https://en.wikipedia.org/wiki/Gaussian_blur#Mathematics
|
||||||
|
--Eye adaptation, decreases or increases the brightness
|
||||||
|
of bloom according to the overall image luminance.
|
||||||
|
--Lens dirt, as standard I suppose. Really not much here.
|
||||||
|
It uses an image named "MagicBloom_Dirt.png" so make
|
||||||
|
sure you have one in your textures directory.
|
||||||
|
--Unwanted features can be disabled through
|
||||||
|
preprocessor definitions, saving performance.
|
||||||
|
|
||||||
|
Preprocessor definitions:
|
||||||
|
--MAGICBLOOM_ADAPT_RESOLUTION:
|
||||||
|
Determines the width/height of the texture used for adaptation.
|
||||||
|
It is recommended to use 256, but you can use as far as 1024 without issues.
|
||||||
|
Too low resolutions will make adaptation seem "unstable".
|
||||||
|
Must be a power of two value: 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024 etc.
|
||||||
|
--MAGICBLOOM_BLUR_PRECALCULATED:
|
||||||
|
If set to 0 the gaussian blur will be calculated inside the shader.
|
||||||
|
Otherwise, it uses a pre-calculated kernel (array).
|
||||||
|
|
||||||
|
--MAGICBLOOM_NODIRT:
|
||||||
|
If set to 1 all lens dirt related features are disabled.
|
||||||
|
Beneficial for performance if you don't wish to use lens dirt.
|
||||||
|
--MAGICBLOOM_NOADAPT:
|
||||||
|
If set to 1 all adaptation related features are disabled.
|
||||||
|
Beneficial for performance if you don't wish to use adaptation.
