Constructor & Destructor Documentation

template<typename ShaderParameters>

SpecularShaderHelper< ShaderParameters >::SpecularShaderHelper	(	miState *	pState,
		ShaderParameters *	pParameters
	)			[inline]

Constructor for lambertian shader helper.

This will be called once per evaluation of the main shading function for the shader. This stores the state and the parameters for use in various functions.

Parameters:

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

template<typename ShaderParameters>

SpecularShaderHelper< ShaderParameters >::~SpecularShaderHelper

(

)

[inline]

Deconstructor for lambertian shader helper.

This will be called once per evaluation of the main shading function for the shader.

Member Function Documentation

template<typename ShaderParameters>

void SpecularShaderHelper< ShaderParameters >::evaluateParameters

(

)

[inline]

Evaluates shader parameters necessary for later computations.

This function is called after other initialization to give the helper a chance to evaluate any parameters necessary for later computations.

Reimplemented from LambertianShaderHelper< ShaderParameters >.

template<typename ShaderParameters>

void SpecularShaderHelper< ShaderParameters >::setASQWeight	(	MayabaseState *&	MBS,
		BRDFComponent &	bc,
		const miColor &	pColor,
		const miColor &	pTransparency,
		miScalar &	pGlowIntensity
	)			const [inline]

Set the ASQ weight for this shader call.

This function adjusts the ASQ weight according to the light loop's impact on the final shader result.

Parameters:

[in,out]	MBS	The current Maya state.
[in]	bc	BRDF component information.
[in]	pColor	The diffuse color for the shader.
[in]	pTransparency	The transparency for the shader.
[in]	pGlowIntensity	The glow intensity for the shader.

Reimplemented from LambertianShaderHelper< ShaderParameters >.

template<typename ShaderParameters>

float SpecularShaderHelper< ShaderParameters >::computeSpecularAreaLightFactor	(	miVector &	pBumpNormal,
		void *	pLightBlindData
	)			[inline]

Computes the specular factor for area lights.

This function computes the specular factor for area lights.

Parameters:

[in]	pBumpNormal	The normal after bump adjustments.
[in]	pLightBlindData	Custom light shader data.

Returns:

The specular factor for area lights.

template<typename ShaderParameters>

miColor SpecularShaderHelper< ShaderParameters >::getReflectedColor

(

)

const [inline]

Return the reflected color for this shader.

Return the reflected color for this shader.

Returns:

The reflected color for this shader.

Reimplemented from LambertianShaderHelper< ShaderParameters >.
