Member Function Documentation

◆ Create()

bool CShaderDX::Create	(	const std::string &	shaderSource,
		const std::string &	shaderPath,
		ShaderParameterMap	shaderParameters,
		IShaderSampler *	sampler,
		ShaderLutVec	luts,
		float2	viewPortSize,
		unsigned	frameCountMod = `0`
	)

overridevirtual

Construct the vidoe shader instance.

Parameters

shaderSource	Source code of the shader (both vertex and pixel/fragment)
shaderPath	Full path to the shader file
shaderParameters	Struct with all parameters pertaining to the shader
sampler	Pointer to the sampler that the will be used when sampling textures
luts	Look-up textures pertaining to shader
viewPortSize	Size of the window/viewport
frameCountMod	Modulo that must be applied to the frame count before sendign it to the shader

Returns: False if creating the shader failed, true otherwise.

Implements KODI::SHADER::IShader.

◆ CreateInputBuffer()

bool CShaderDX::CreateInputBuffer ( )

overridevirtual

Creates the buffer that will be used to send "input" (as per the spec) data to the shader.

Returns: False if creating the input buffer failed, true otherwise.

Implements KODI::SHADER::IShader.

◆ CreateInputLayout()

bool CShaderDX::CreateInputLayout	(	D3D11_INPUT_ELEMENT_DESC *	layout,
		unsigned	numElements
	)

virtual

Creates the data layout of the input-assembler stage.

Parameters

layout	Description of the inputs to the vertex shader
numElements	Number of inputs to the vertex shader

Returns: False if creating the input layout failed, true otherwise.

Reimplemented from CWinShader.

◆ CreateVertexBuffer()

bool CShaderDX::CreateVertexBuffer	(	unsigned	vertCount,
		unsigned	vertSize
	)

overridevirtual

Construct the vertex buffer that will be used to render the shader.

Parameters

vertCount	Number of vertices to construct. Commonly 4, for rectangular screens.
vertSize	Size of each vertex's data in bytes

Returns: False if creating the vertex buffer failed, true otherwise.

Implements KODI::SHADER::IShader.

◆ PrepareParameters()

void CShaderDX::PrepareParameters	(	CPoint	dest[4],
		bool	isLastPass,
		uint64_t	frameCount
	)

overridevirtual

Called before rendering. Updates any internal state needed to ensure that correct data is passed to the shader when rendering.

Parameters

dest	Coordinates of the 4 corners of the output viewport/window
isLastPass	True if the current shader is last one in the pipeline // TODO: this could be a member
frameCount	Number of frames that have passed

Implements KODI::SHADER::IShader.

◆ Render()

void CShaderDX::Render	(	IShaderTexture *	source,
		IShaderTexture *	target
	)

overridevirtual

Renders the video shader to the target texture.

Parameters

source	Source texture to pass to the shader as input
target	Target texture to render the shader to

Implements KODI::SHADER::IShader.

◆ SetSizes()

void CShaderDX::SetSizes	(	const float2 &	prevSize,
		const float2 &	nextSize
	)

overridevirtual

Sets the input and output sizes in pixels.

Parameters

prevSize	Input image size of the shader in pixels
nextSize	Output image size of the shader in pixels

Implements KODI::SHADER::IShader.
