Member Function Documentation

computeCurrentRadiance()

DoubleVec3D Material::computeCurrentRadiance ( const DoubleVec3D &  recursiveRadiance, double  cosAngleNewDirectionNormal, bool  nextEventEstimation = false  ) const

pure virtual

Computes the new radiance.

Parameters

recursiveRadiance	The radiance recursively obtained.
cosAngleNewDirectionNormal	The cosine of the angle between the direction of the next ray and the normal at the intersection.
nextEventEstimation	Whether the radiance is obtained using the next event estimation algorithm.

Returns

The new radiance.

Implemented in SpecularMaterial, RefractiveMaterial, and DiffuseMaterial.

deepCopy()

Material * Material::deepCopy ( ) const

pure virtual

Makes a deep copy of this material.

Returns

A pointer to a deeply copied version of this material.

Implemented in SpecularMaterial, RefractiveMaterial, and DiffuseMaterial.

getDescription()

std::ostream & Material::getDescription ( std::ostream &  stream ) const

pure virtual

Returns this material's description.

Parameters

stream

The current stream.

Returns

The stream with the description.

getNewDirection()

DoubleUnitVec3D Material::getNewDirection ( const Ray &  previousRay, const DoubleUnitVec3D &  normal  ) const

pure virtual

Computes the new ray direction.

Parameters

previousRay	The ray that hits this material.
normal	The normal at the intersection.

Returns

The new ray direction.

Implemented in SpecularMaterial, RefractiveMaterial, and DiffuseMaterial.

getSpecificParametersJson()

json Material::getSpecificParametersJson ( ) const

pure virtual

Converts this material's specific parameters to json.

Returns

This material's specific parameters converted to json.

Implemented in SpecularMaterial, RefractiveMaterial, and DiffuseMaterial.

getType()

std::string Material::getType ( ) const

pure virtual

Returns this material type.

Returns

"Diffuse", "Refractive" or "Specular", depending on the material instance.

setEmittance()

void Material::setEmittance

(

DoubleVec3D

emittance

)

Setter for the emittance attribute.

Parameters

emittance

The new emittance of this material.

setSpecificParametersJson()

void Material::setSpecificParametersJson ( const json &  j )

pure virtual

Sets this material's specific parameters according to json.

Parameters

j	The json input.

Implemented in SpecularMaterial, RefractiveMaterial, and DiffuseMaterial.

worksWithNextEventEstimation()

bool Material::worksWithNextEventEstimation ( ) const

pure virtual

Returns whether this material works with next event estimation.

Returns

True if this material works with the next event estimation algorithm, false else.

Implemented in SpecularMaterial, RefractiveMaterial, and DiffuseMaterial.
