    Modifications
     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
     Peter Vanroose 21 May  2009: istream operator>> re-implemented

Function Documentation

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

Definition at line 141 of file vgl_plane_3d.h.

template<class T >

vcl_ostream & operator<<	(	vcl_ostream &	s,
		const vgl_plane_3d< T > &	p
	)

Write to stream.

Definition at line 81 of file vgl_plane_3d.txx.

template<class T >

vcl_istream & operator>>	(	vcl_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"
