ShapeGaussianCurvatureFunctor()

template<typename TShape >

DGtal::functors::ShapeGeometricFunctors::ShapeGaussianCurvatureFunctor< TShape >::ShapeGaussianCurvatureFunctor ( ConstAlias< Shape > aShape = 0 )

inline

Constructor. A shape may also be attached at construction.

Parameters

aShape

the shape of interest. The alias can be secured if a some counted pointer is handed.

void DGtal::functors::ShapeGeometricFunctors::ShapeGaussianCurvatureFunctor< TShape >::attach ( ConstAlias< Shape > aShape )

inline

Attach a shape.

Parameters

aShape

the shape of interest. The alias can be secured if a some counted pointer is handed.
