Detailed Description

Material shader class.

This class holds all data and behaviors which are specific to mental ray material shaders. It is an extension of the base class Shader.

Template Parameters:

	MaterialParameters	The material parameter structure.
	ShaderHelper	The shader helper to use with this shader.
	VERSION	The version of this shader. Should match the version of the shader declared in the .mi file.


Public Member Functions
	Material (miState pState, MaterialParameters pParameters)
	Material shader constructor.
virtual	~Material ()
	Material shader destructor.
miBoolean	operator() (miColor pResult, miState pState, MaterialParameters *pParameters)
	Main shading function.
template<typename T>
void	writeToFrameBuffers (miState pState, FrameBufferInfo pFrameBufferInfo, PassTypeInfo pPassTypeInfo, const T &pValue, PassTypeID pPassType, const bool &pUseIrradiance, const miColor const &pIrradianceNoShadow=0)
	Write to frame buffers of a given type.
Protected Attributes
miInteger	mFrameBufferWriteOperation
	Operation to be performed on frame buffers.
miInteger	mFrameBufferWriteFlags
	Flags affecting the frame buffer operation.
miScalar	mFrameBufferWriteFactor
	Scaling factor for contribution if scaling is enabled.

template<typename MaterialParameters, typename ShaderHelper, int VERSION>

Material< MaterialParameters, ShaderHelper, VERSION >::Material	(	miState *	pState,
		MaterialParameters *	pParameters
	)			`[inline]`

Material shader constructor.

This will be called once per shader instance, and is where data for each shader instance should be initialized.

Parameters:

`[in,out]`	pState	A pointer to the mental ray state structure.
`[in]`	pParameters	A pointer to the shader parameters.

template<typename MaterialParameters, typename ShaderHelper, int VERSION>

Material< MaterialParameters, ShaderHelper, VERSION >::~Material ( ) [inline, virtual]

Material shader destructor.

The member variables mDestructorState and mDestructorParameters will be set correctly when the destructor is called.

template<typename MaterialParameters, typename ShaderHelper, int VERSION>

miBoolean Material< MaterialParameters, ShaderHelper, VERSION >::operator()	(	miColor *	pResult,
		miState *	pState,
		MaterialParameters *	pParameters
	)			`[inline]`

Main shading function.

This is the function which is called for shader samples.

Parameters:

`[out]`	pResult	A pointer to the mental ray color result.
`[in,out]`	pState	A pointer to the mental ray state structure.
`[in]`	pParameters	A pointer to the shader parameters.

template<typename MaterialParameters, typename ShaderHelper, int VERSION>

template<typename T>

void Material< MaterialParameters, ShaderHelper, VERSION >::writeToFrameBuffers	(	miState *	pState,
		FrameBufferInfo *	pFrameBufferInfo,
		PassTypeInfo *	pPassTypeInfo,
		const T &	pValue,
		PassTypeID	pPassType,
		const bool &	pUseIrradiance,
		const miColor *const &	pIrradianceNoShadow = `0`
	)			`[inline]`

Write to frame buffers of a given type.

Parameters:

`[in,out]`	pState	The shading state
`[in,out]`	pFrameBufferInfo	The array of frame buffer information structs
`[in]`	pPassTypeInfo	The array of pass type information structs
`[in]`	pValue	The value to be written to the frame buffer
`[in]`	pPassType	The pass type ID that identifies the frame buffer to be written to
`[in]`	pUseIrradiance	Set to true if the value should be modulated by irradiance. This option should only be used inside a light loop.
`[in]`	pIrradianceNoShadow	Sample irradiance without shadows, used to compute differential shadow passes. When non-null, the difference between pIrradianceNoShadow and the sample irradiance is used as a lighting factor, instead of the sample irradiance.
