Detailed Description

template<class DataPoint>
class Ponca::GlobalNeighborhoodFrame< DataPoint >

NeighborhoodFrame that keep points in the global frame without applying any transformation This class is useful to compute direct fits in the embedding space, without paying the cost to express neighbors relatively to an evaluation point.

Warning

In case the data have strong magnitude (e.g., georeferenced point clouds), it is recommended to use CenteredNeighborhoodFrame instead.

Note

This class is designed to serve as a Base class for the definition of NeighborFilters, and cannot be used directly

changeNeighborhoodFrame()

template<class DataPoint >

void Ponca::GlobalNeighborhoodFrame< DataPoint >::changeNeighborhoodFrame ( const VectorType &  )

inline

Change neighborhood frame (has no effect for global basis)

Warning

Calling this method invalidates any primitive defined relatively to the previous frame. In this situation, it is recommended to use ProvidesImplicitPrimitive::changeBasis instead.

convertToGlobalBasis()

template<class DataPoint >

const VectorType & Ponca::GlobalNeighborhoodFrame< DataPoint >::convertToGlobalBasis ( const VectorType &  _q, bool  = true  ) const

inline

Convert position from local to global coordinate system : does nothing as this is global frame.

Parameters

_q	Position in local coordinate
_isPositionVector	Indicate if the input vector _q is a position that is influenced by translations (e.g., in contrast to displacement or normal vectors)

Returns

_q

Definition at line 132 of file frame.h.

convertToLocalBasis()

template<class DataPoint >

const VectorType & Ponca::GlobalNeighborhoodFrame< DataPoint >::convertToLocalBasis ( const VectorType &  _q, bool  = true  ) const

inline

Convert query from global to local coordinate system : does nothing as this is global frame.

Parameters

_q	Query in global coordinate
_isPositionVector	Indicate if the input vector _q is a position that is influenced by translations (e.g., in contrast to displacement or normal vectors)

Returns

_q
