Detailed Description

HeightToNormal node implementation for GLSL.

Member Function Documentation

◆ acceptsInputType()

bool acceptsInputType ( const 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.

◆ 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.
