   Peter Vanroose  6 July 2001: Added assertion in constructors
   Peter Vanroose  6 July 2001: Now using vgl_vector_3d for normal direction
   Peter Vanroose  6 July 2001: Implemented constructor from 3 points
   Peter Vanroose  6 July 2001: Added normal(); replaced data_[4] by a_ b_ c_ d_
   Peter Vanroose  6 July 2001: Added operator== and operator!=
   Peter Vanroose 19 Aug. 2004: implementation of both constructors corrected

Function Documentation

is_ideal()

template<class T >

bool is_ideal ( vgl_plane_3d< T > const &  , T  tol = (T)0  )

inline

Return true iff p is the plane at infinity.

Always returns false

operator<<()

template<class T >

std::ostream & operator<<	(	std::ostream &	s,
		const vgl_plane_3d< T > &	p
	)

Write to stream.

operator>>()

template<class T >

std::istream & operator>>	(	std::istream &	is,
		vgl_plane_3d< T > &	p
	)

Read in four plane parameters from stream.

Either just reads four blank-separated numbers, or reads four comma-separated numbers, or reads four numbers in parenthesized form "(123, 321, -456, 777)" or reads a formatted line equation "123x+321y-456z+777=0"
