template<typename TVCMOnDigitalSurface >
DGtal::functors::VCMNormalVectorFunctor< TVCMOnDigitalSurface >::VCMNormalVectorFunctor ( ConstAlias< VCMOnDigitalSurface aVCMOnDigitalSurface = 0)
inline

Constructor. A VCM may also be attached at construction.

Parameters
aVCMOnDigitalSurfacethe VCM on surface that stores all the information. The alias can be secured if some counted pointer is handed.

Definition at line 75 of file VCMGeometricFunctors.h.

Member Function Documentation

template<typename TVCMOnDigitalSurface >
void DGtal::functors::VCMNormalVectorFunctor< TVCMOnDigitalSurface >::attach ( ConstAlias< VCMOnDigitalSurface aVCMOnDigitalSurface)
inline

Attach a VCM on a digital surface.

Parameters
aVCMOnDigitalSurfaceon surface that stores all the information. The alias can be secured if some counted pointer is handed.

template<typename TVCMOnDigitalSurface >
Quantity DGtal::functors::VCMNormalVectorFunctor< TVCMOnDigitalSurface >::operator() ( const Surfel s) const
inline

Map operator Surfel -> RealVector giving the normal vector estimated by the VCM object. Complexity is \( O(log n) \), if n is the number of surfels of the surface.

Parameters
sany surfel of the shape.
Returns
the normal at point p (as the normalized gradient).
