Public Functions

inline CPoint2D()

inline CPoint2D(double x, double y)

Constructor for initializing point coordinates.

template<class OTHERCLASS, std::size_t DIM2>
inline explicit CPoint2D(const CPoseOrPoint<OTHERCLASS, DIM2> &b)

Constructor from x/y coordinates given from other pose.

explicit CPoint2D(const mrpt::math::TPoint2D &o)

Explicit constructor from lightweight type.

explicit CPoint2D(const mrpt::math::TPoint3D &o)

Explicit constructor from lightweight type (loses the z coord).

mrpt::math::TPoint2D asTPoint() const

inline void asVector(vector_t &v) const

Return the pose or point as a 2x1 vector [x, y]’

CPoint2D operator-(const CPose2D &b) const

The operator D=”this”-b is the pose inverse compounding operator, the resulting points “D” fulfils: “this” = b + D, so that: b == a + (b-a)
