Detailed Description

represents a frame transformation in 3D space (rotation + translation)

if V2 = Frame*V1 (V2 expressed in frame A, V1 expressed in frame B) then V2 = Frame.M*V1+Frame.p

Frame.M contains columns that represent the axes of frame B wrt frame A Frame.p contains the origin of frame B expressed in frame A.

Returns:: the identity transformation Frame(Rotation::Identity(),Vector::Zero()).

void KDL::Frame::Integrate	(	const Twist &	t_this,

The twist <t_this> is expressed wrt the current frame. This frame is integrated into an updated frame with <samplefrequency>. Very simple first order integration rule.

Gives back inverse transformation of a Frame.

Vector KDL::Frame::Inverse ( const Vector & arg ) const [inline]

The same as p2=R.Inverse()*p but more efficient.

Wrench KDL::Frame::Inverse ( const Wrench & arg ) const [inline]

The same as p2=R.Inverse()*p but more efficient.

Twist KDL::Frame::Inverse ( const Twist & arg ) const [inline]

The same as p2=R.Inverse()*p but more efficient.

void KDL::Frame::Make4x4 ( double * d )

Reads data from an double array.

double KDL::Frame::operator()	(	int	i,
		int	j
	)		`[inline]`

Treats a frame as a 4x4 matrix and returns element i,j Access to elements 0..3,0..3, bounds are checked when NDEBUG is not set

double KDL::Frame::operator()	(	int	i,
		int	j
	)		const `[inline]`

Treats a frame as a 4x4 matrix and returns element i,j Access to elements 0..3,0..3, bounds are checked when NDEBUG is not set

Vector KDL::Frame::operator* ( const Vector & arg ) const [inline]

Transformation of the base to which the vector is expressed.

Wrench KDL::Frame::operator* ( const Wrench & arg ) const [inline]

Transformation of both the force reference point and of the base to which the wrench is expressed. look at Rotation*Wrench operator for a transformation of only the base to which the twist is expressed.

Complexity : 24M+18A

Twist KDL::Frame::operator* ( const Twist & arg ) const [inline]

Transformation of both the velocity reference point and of the base to which the twist is expressed. look at Rotation*Twist for a transformation of only the base to which the twist is expressed.

Complexity : 24M+18A

Frame& KDL::Frame::operator= ( const Frame & arg ) [inline]

Normal copy-by-value semantics.

bool Equal	(	const Frame &	a,
		const Frame &	b,
		double	eps = `epsilon`
	)		`[friend]`

do not use operator == because the definition of Equal(.,.) is slightly different. It compares whether the 2 arguments are equal in an eps-interval

bool operator!=	(	const Frame &	a,
		const Frame &	b
	)		`[friend]`

The literal inequality operator!=().

Frame operator*	(	const Frame &	lhs,
		const Frame &	rhs
	)		`[friend]`

Composition of two frames.

bool operator==	(	const Frame &	a,
		const Frame &	b
	)		`[friend]`

The literal equality operator==(), also identical.
