Detailed Description

template<typename T>
struct DGtal::concepts::CNormalVectorEstimator< T >

Aim: Represents the concept of estimator of normal vector along digital surfaces.

Description of concept 'CNormalVectorEstimator'

Refinement of

Associated types

Surface : the type of digital surface (must be some DigitalSurface<X>)
ConstIterator : an iterator on the signed cells of the digital surface (same as Surface::ConstIterator).
SCell : the type of signed cell (for surfels along the digital surface) (same as Surface::SCell).
Quantity: the type representing normal vectors.

Notation

X : A type that is a model of CNormalVectorEstimator
x : object of type X
sc : object of type SCell
out_it : an OutputIterator on Quantity

Definitions

Valid expressions and semantics

Name	Expression	Return type	Semantics
Accessor to surface	x.surface()	const Surface &	returns a reference to the digital surface
Local normal vector estimation	x.eval(sc)	Quantity	returns the estimation of the normal vector at the signed cell sc
Global normal vector estimation	`template` <OutputIterator>x.evalAll(out_it)	OutputIterator	outputs the estimation of the normal vector field of the whole surface
