virtual bool ConvolutionNode::acceptsInputType ( const TypeDesc * type ) const

protectedpure virtual

Derived classes are responsible for returning if a given type is an acceptable input.

Implemented in HeightToNormalNodeGlsl, HeightToNormalNodeMsl, BlurNode, and HeightToNormalNodeMdl.

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

protectedpure virtual

Implemented in HeightToNormalNodeGlsl, HeightToNormalNodeMsl, BlurNode, and HeightToNormalNodeMdl.

void ConvolutionNode::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 ShaderNodeImpl.

void ConvolutionNode::emitInputSamplesUV	(	const ShaderNode &	node,
		unsigned int	sampleCount,
		unsigned int	filterWidth,
		float	filterSize,
		float	filterOffset,
		const string &	sampleSizeFunctionUV,
		GenContext &	context,
		ShaderStage &	stage,
		StringVec &	sampleStrings
	)		const

protected

Generate upstream / input sampling code in uv space and cache the output variable names which will hold the sample values after execution.

virtual const ShaderInput* ConvolutionNode::getSamplingInput ( const ShaderNode & node ) const

protectedvirtual

Get input which is used for sampling. If there is none then a null pointer is returned.
