Detailed Description

template<typename P>
struct mln::Point< P >

Base class for implementation of point classes.

A point is an element of a space.

For instance, mln::point2d is the type of elements defined on the discrete square grid of the 2D plane.

template<typename P, typename D>

P & operator+=	(	Point< P > &	p,
		const Dpoint< D > &	dp
	)			[related]

Shift a point by a delta-point dp.

Parameters:

[in,out]	p	The targeted point.
[in]	dp	A delta-point.

Returns:

A reference to the point p once translated by dp.

Precondition:

The type of dp has to be compatible with the type of p.

template<typename P, typename D>

P & operator-=	(	Point< P > &	p,
		const Dpoint< D > &	dp
	)			[related]

Shift a point by the negate of a delta-point dp.

Parameters:

[in,out]	p	The targeted point.
[in]	dp	A delta-point.

Returns:

A reference to the point p once translated by - dp.

Precondition:

The type of dp has to be compatible with the type of p.

Definition at line 149 of file concept/point.hh.

template<typename P, typename D>

P & operator/	(	Point< P > &	p,
		const value::Scalar< D > &	dp
	)			[related]

Divise a point by a scalar s.

Parameters:

[in,out]	p	The targeted point.

Returns:

A reference to the point p once divised by s.
