Classes
class	CenteredNeighborhoodFrame
	NeighborhoodFrame that express 3d points relatively to a prescribed center. More...
struct	CNCEigen
	This class contains some stand-alone CorrectedNormalCurrent formulas for triangles, using eigen as linear algebra backend. More...
class	CurvatureEstimatorBase
	Base class for any 3d curvature estimator: holds \(k_{\min}\), \(k_{\max}\) and associated vectors, such that \( k_{\min} <= k_{\max} \). More...
class	GlobalNeighborhoodFrame
	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. More...
struct	HexagramBase
class	NoWeightFuncBase
	Weighting function that set uniform weight to all samples. More...
struct	Triangle
	Stores the three points and normals of the triangles and provides access to Corrected Normal Current formula. More...
struct	TriangleGenerator
struct	TriangleGenerator< AvgHexagramGeneration, P >
struct	TriangleGenerator< HexagramGeneration, P >
struct	TriangleGenerator< IndependentGeneration, P >
struct	TriangleGenerator< UniformGeneration, P >
class	WeingartenCurvatureEstimatorBase
	Compute principal curvatures from a base class providing fundamental forms. More...
