Member Function Documentation

◆ acceptsInputType()

bool acceptsInputType ( TypeDesc type ) const

overrideprotectedvirtual

Return if given type is an acceptible input.

Implements ConvolutionNode.

◆ computeSampleOffsetStrings()

void computeSampleOffsetStrings	(	const string &	sampleSizeName,
		const string &	offsetTypeString,
		unsigned int	filterWidth,
		StringVec &	offsetStrings
	)		const

overrideprotectedvirtual

Compute offset strings for sampling.

Implements ConvolutionNode.

◆ createVariables()

void createVariables	(	const ShaderNode &	node,
		GenContext &	context,
		Shader &	shader
	)		const

overridevirtual

Create shader variables needed for the implementation of this node (e.g.

uniforms, inputs and outputs). Used if the node requires input data from the application.

Reimplemented from ConvolutionNode.

◆ emitFunctionCall()

void emitFunctionCall	(	const ShaderNode &	node,
		GenContext &	context,
		ShaderStage &	stage
	)		const

overridevirtual

Emit the function call or inline source code for given node instance in the given context.

Reimplemented from ShaderNodeImpl.

◆ emitFunctionDefinition()

void emitFunctionDefinition	(	const ShaderNode &	node,
		GenContext &	context,
		ShaderStage &	stage
	)		const

overridevirtual

Emit function definition for the given node instance.

Reimplemented from ShaderNodeImpl.

◆ getTarget()

const string & getTarget ( ) const

overridevirtual

Return an identifier for the target used by this implementation.

By default an empty string is returned, representing all targets. Only override this method if your derived node implementation class is for a specific target.

Reimplemented from ShaderNodeImpl.
