// Use "SORT_NAME" to specify the name used for sorting, otherwise the files will be sorted by their file names.

// Definition of parameters
//!PARAMETER
// "LABEL" refers to the name of the parameter that is displayed on the user interface.
//!LABEL Sharpness
// "DEFAULT", "MIN", "MAX", and "STEP" are all required.
//!DEFAULT 0.1
//!MIN 0.01
//!MAX 5
//!STEP 0.01
float sharpness;


// Definition of textures
// "INPUT" and "OUTPUT" are special keywords.
// "INPUT" cannot be used as the output of a pass; "OUTPUT" cannot be used as the input of a pass.
// Defining INPUT/OUTPUT is optional, but it is recommended to define them explicitly for the sake of semantic completeness.
// The size of the OUTPUT represents the output size of this effect. Not specifying it indicates support for output of any size.

//!TEXTURE
Texture2D INPUT;

//!TEXTURE
//!WIDTH INPUT_WIDTH * 2
//!HEIGHT INPUT_HEIGHT * 2
Texture2D OUTPUT;

// You can use some pre-defined constants to calculate texture size.
// INPUT_WIDTH
// INPUT_HEIGHT
// OUTPUT_WIDTH
// OUTPUT_HEIGHT

// Supported texture formats:
// R32G32B32A32_FLOAT
// R16G16B16A16_FLOAT
// R16G16B16A16_UNORM
// R16G16B16A16_SNORM
// R32G32_FLOAT
// R10G10B10A2_UNORM
// R11G11B10_FLOAT
// R8G8B8A8_UNORM
// R8G8B8A8_SNORM
// R16G16_FLOAT
// R16G16_UNORM
// R16G16_SNORM

// R8G8_UNORM
// R8G8_SNORM
// R16_FLOAT
// R16_UNORM
// R16_SNORM
// R8_UNORM
// R8_SNORM
// The definition of a texture in a pass varies depending on its format. For example,
// when the texture format is R8G8_UNORM, its definition as an input is Texture2D<float2>,
// and as an output it is RWTexture2D<unorm float2>.

// "FILTER" is required，"ADDRESS" is optional
// The default value of "ADDRESS" is "CLAMP"

//!PASS 1
// This description will appear in the in-game overlay.
//!DESC First Pass
// You can use a PS-like style, but it will still be implemented with CS.
// The default value of "STYLE" is "CS".

// The output of the last pass must be "OUTPUT".
//!OUT OUTPUT
// "BLOACK_SIZE" specifies how large an area is processed in one dispatch.
// "BLOACK_SIZE" can have only one dimension, meaning that length and height are specified at the same time.
//!BLOCK_SIZE 16, 16
// "NUM_THREADS" specifies how many parallel threads are involved in a single dispatch.
// "NUM_THREADS" can be less than three dimensions, and the missing dimensions are assumed to be 1 by default.
