Detailed Description

template<class P, class NF, template< class, class, typename > class Ext0, template< class, class, typename > class... Exts>
class Ponca::Basket< P, NF, Ext0, Exts >

Aggregator class used to declare specialized structures using CRTP.

Base ComputeObject for the Basket classes.

Implements the compute methods for fitting: compute, computeWithIds, ... Checkout Fitting Module: User Manual for more details

The various implementations of Ponca::Concept are mixed through specializations of the BasketDiff and Basket classes:

typedef
BasketDiff <BasketType,           // Existing Basket, to be differentiated
DiffType,                         // Differentiation space: FitScaleDer, FitSpaceDer, or FitScaleDer|FitSpaceDer
ComputationalDerivativesConcept1, // Implementation of ComputationalDerivativesConcept
ComputationalDerivativesConcept2, // Implementation of ComputationalDerivativesConcept
... ,                             //
> myFitDer;                       // Final structure to fit and derive a primitive over weighted samples

Template Parameters

Derived	Derived class that provides the addNeighbor method (either Basket or BasketDiff)
Base	Base class that provides, through the CRTP the init, startNewPass, addNeighbor and finalize methods
P	Implements PointConcept
W	Implements WeightKernelConcept

Exts	Implements ComputationalObjectConcept (optional)

Member Function Documentation

addNeighbor()

template<class P , class NF , template< class, class, typename > class Ext0, template< class, class, typename > class... Exts>

bool Ponca::Basket< P, NF, Ext0, Exts >::addNeighbor ( const DataPoint &  _nei )

inline

Add a neighbor to perform the fit.

When called directly, don't forget to call PrimitiveBase::startNewPass when starting multiple passes

See also

compute Prefer when using a range of Points

computeWithIds Prefer when using a range of ids

Returns

false if param nei is not a valid neighbor (weight = 0)

VectorType Ponca::Basket< P, NF, Ext0, Exts >::projectDescent ( const VectorType &  _q, int  nbIter = 16  ) const

inline

Project a point on the primitive using Gradient Descent This projection is realized by following the gradient of the primitive scalar field.

Warning

This function is in most cases slower than #project.

Parameters

nbIter	Number of iterations (default = 16)
