Detailed Description

class shapeworks::VectorFunction;

This is the base class defining the API for a function that takes a particle system, domain, and location index as arguments and returns a vector-valued result.

Public Functions Documentation

function itkTypeMacro

itkTypeMacro(
    VectorFunction ,
    LightObject 
)

function itkStaticConstMacro

itkStaticConstMacro(
    Dimension ,
    unsigned int ,
    VDimension 
)

Method for object allocation through the factory. Dimensionality of the domain of the particle system.

function Evaluate

virtual VectorType Evaluate(
    unsigned int ,
    unsigned int ,
    const ParticleSystem * ,
    double & maxtimestep
) const =0

Reimplemented by: shapeworks::CorrespondenceFunction::Evaluate, shapeworks::DisentangledCorrespondenceFunction::Evaluate, shapeworks::LegacyCorrespondenceFunction::Evaluate, shapeworks::SamplingFunction::Evaluate, shapeworks::DualVectorFunction::Evaluate

The first argument is a pointer to the particle system. The second argument is the index of the domain within that particle system. The third argument is the index of the particle location within the given domain.

function Evaluate

virtual VectorType Evaluate(
    unsigned int ,
    unsigned int ,
    const ParticleSystem * ,
    double & maxtimestep,
    double & energy
) const =0

Reimplemented by: shapeworks::DualVectorFunction::Evaluate, shapeworks::CorrespondenceFunction::Evaluate, shapeworks::DisentangledCorrespondenceFunction::Evaluate, shapeworks::LegacyCorrespondenceFunction::Evaluate, shapeworks::SamplingFunction::Evaluate

function Energy

virtual double Energy(
    unsigned int ,
    unsigned int ,
    const ParticleSystem * 
) const =0

Reimplemented by: shapeworks::CorrespondenceFunction::Energy, shapeworks::DisentangledCorrespondenceFunction::Energy, shapeworks::LegacyCorrespondenceFunction::Energy, shapeworks::SamplingFunction::Energy, shapeworks::DualVectorFunction::Energy

function ResetBuffers

inline virtual void ResetBuffers()

Reimplemented by: shapeworks::SamplingFunction::ResetBuffers

May be called by the solver class.

function AfterIteration

inline virtual void AfterIteration()

Reimplemented by: shapeworks::CorrespondenceFunction::AfterIteration, shapeworks::DisentangledCorrespondenceFunction::AfterIteration, shapeworks::DualVectorFunction::AfterIteration, shapeworks::LegacyCorrespondenceFunction::AfterIteration

This method is called by a solver after each iteration. Subclasses may or may not implement this method.

function BeforeIteration

inline virtual void BeforeIteration()

Reimplemented by: shapeworks::CorrespondenceFunction::BeforeIteration, shapeworks::DisentangledCorrespondenceFunction::BeforeIteration, shapeworks::DualVectorFunction::BeforeIteration, shapeworks::LegacyCorrespondenceFunction::BeforeIteration

This method is called by a solver before each iteration. Subclasses may or may not implement this method.

function BeforeEvaluate

inline virtual void BeforeEvaluate(
    unsigned int ,
    unsigned int ,
    const ParticleSystem * 
)

Reimplemented by: shapeworks::DualVectorFunction::BeforeEvaluate, shapeworks::SamplingFunction::BeforeEvaluate

This method may be called to set up the state of the function object before a call to Evaluate. It is necessary in order to initialize certain constants and variables that may be used for calculating the Energy as well as the Gradients. Typically this is only necessary for the adaptive gradient descent algorithm.

function SetParticleSystem

inline virtual void SetParticleSystem(
    ParticleSystem * p
)

Reimplemented by: shapeworks::DualVectorFunction::SetParticleSystem

Some subclasses may require a pointer to the particle system and its domain number. These methods set/get those values.

function GetParticleSystem

inline virtual ParticleSystem * GetParticleSystem() const

function SetDomainNumber

inline virtual void SetDomainNumber(
    unsigned int i
)

Reimplemented by: shapeworks::DualVectorFunction::SetDomainNumber

function GetDomainNumber

inline virtual int GetDomainNumber() const

function Clone

inline virtual VectorFunction::Pointer Clone()

Reimplemented by: shapeworks::CorrespondenceFunction::Clone, shapeworks::DisentangledCorrespondenceFunction::Clone, shapeworks::DualVectorFunction::Clone, shapeworks::LegacyCorrespondenceFunction::Clone, shapeworks::SamplingFunction::Clone

function GetRelativeEnergyScaling

inline virtual double GetRelativeEnergyScaling() const

Reimplemented by: shapeworks::DualVectorFunction::GetRelativeEnergyScaling

function SetRelativeEnergyScaling

inline virtual void SetRelativeEnergyScaling(
    double r
)

Reimplemented by: shapeworks::DualVectorFunction::SetRelativeEnergyScaling
