Plane_separator<FT>

advanced

Definition

The class Plane_separator<FT> implements a plane separator, i.e., a hyperplane that is used to separate two half spaces. This hyperplane is defined by a cutting dimension d and a cutting value v as x_d=v, where v denotes the d^th coordinate value.

Creation

Plane_separator<FT> s ( int d, FT v);
	Constructs a separator that separates two half spaces by a hyperplane defined by x_d=v, where v denotes the d^th coordinate value.

Plane_separator<FT> s ( p);
	Copy constructor.

Operations

void	s.set_cutting_dimension ( int d)	Sets the cutting dimension to d.

void	s.set_cutting_value ( FT v)	Sets the cutting value to v.

int	s.cutting_dimension ()	Returns the number of the cutting dimension.

FT	s.cutting_value ()	Returns the cutting value.

template <class SpatialPoint>
bool	s.has_on_negative_side ( SpatialPoint p)
		Returns true if and only if the coordinate of p in the cutting dimension is smaller than the cutting value.

Plane_separator<FT>	s = s2	Assignment operator.

Output Operators

template<class FT>
std::ostream&	std::ostream& os << s	Inserts the plane separator s in the output stream os and returns os.
