Grenaille::Concept::PointConcept Class Reference

Detailed Description

Definition of a point sample.

All fitting methods in Grenaille rely on the definition of a Point type. Specific features might be required depending on the content of the Basket: for instance, an OrientedSphereFit will require points equipped with normals as illustrated in the User Manual.

Grenaille does not provide an implementation for this concept so that users may adapt it to their own data structure. However, the following implementation can be used as a starting point for most 3D applications:

class MyPoint{
public:
  enum {Dim = 3};
  typedef float Scalar;
  typedef Eigen::Matrix<Scalar, Dim, 1> VectorType;

  MULTIARCH inline MyPoint(const VectorType &pos = VectorType::Zero())
    : _pos(pos) {}
    
  MULTIARCH inline const VectorType& pos() const { return _pos; }  
  MULTIARCH inline       VectorType& pos()       { return _pos; }  

private:
  VectorType _pos;
};

Public Types
enum	{ Dim = 3 }
	Defines the ambient space dimension, 3 in this example.
typedef float	Scalar
	Defines the type used ton encode scalar values.
typedef Eigen::Matrix< Scalar, Dim, 1 >	VectorType
	Defines type used ton encode vector values.

Public Member Functions
	PointConcept ()
	Default constructor.
const VectorType &	pos () const
	Read access to the position property.
VectorType &	pos ()
	Write access to the position property.
