Member Function Documentation

void lti::geometricTransform::parameters::clear ( void )

This function erase the tranfomation matrix,translation vector and the rotation center.

The matrix is overwriten with the unit matrix.

virtual functor::parameters* lti::geometricTransform::parameters::clone ( ) const [virtual]

Returns a pointer to a clone of the parameters.

Reimplemented from lti::modifier::parameters.

parameters& lti::geometricTransform::parameters::copy ( const parameters & other )

Copy the contents of a parameters object.

Parameters:

other

the parameters object to be copied

Returns:: a reference to this parameters object

Reimplemented from lti::modifier::parameters.

const char* lti::geometricTransform::parameters::getTypeName ( ) const [virtual]

Returns name of this type.

Reimplemented from lti::modifier::parameters.

void lti::geometricTransform::parameters::invert ( )

Invert the homogeneous transformation matrix.

parameters& lti::geometricTransform::parameters::operator= ( const parameters & other )

Copy the contents of a parameters object.

Parameters:

other

the parameters object to be copied

Returns:: a reference to this parameters object

virtual bool lti::geometricTransform::parameters::read	(	ioHandler &	handler,
		const bool	complete = `true`
	)			`[virtual]`

Write the parameters in the given ioHandler.

Parameters:

	handler	the ioHandler to be used
	complete	if true (the default) the enclosing begin/end will be also written, otherwise only the data block will be written.

Returns:: true if write was successful

Reimplemented from lti::modifier::parameters.

void lti::geometricTransform::parameters::rotate ( const double & angle )

Special rotate function with the center set to the origin: The rotation axis is set to the z-axis.

void lti::geometricTransform::parameters::rotate	(	const tpoint3D< double > &	center,
		const tpoint3D< double > &	axis,
		const double &	angle
	)

Multiply the existing matrix with a rotation matrix.

The vectors center and axis have the dimension 3.

Parameters:

	center	this vector is the center of the rotation.
	axis	this vector is the rotation-axis.
	angle	the rotation angle in radians.

void lti::geometricTransform::parameters::rotate	(	const vector< double > &	center,
		const vector< double > &	axis,
		const double &	angle
	)

Multiply the existing matrix with a rotation matrix.

The vectors center and axis have the dimension 3.

Parameters:

	center	this vector is the center of the rotation.
	axis	this vector is the rotation-axis.
	angle	the rotation angle in radians.

void lti::geometricTransform::parameters::scale ( const double & x )

Special scale function with only one parameter for x, y and z scale

$\begin{bmatrix} x & 0 & 0 & 0 \\ 0 & x & 0 & 0 \\ 0 & 0 & x & 0 \\ 0 & 0 & 0 & 1 \end{bmatrix}$

.

void lti::geometricTransform::parameters::scale ( const tpoint3D< double > & thefPoint )

Set the scaling factor of the homogeneous matrix.

This is achieved multiplying the existing matrix with a resize matrix. If you use this function on an unit matrix you get the following matrix:

$\begin{bmatrix} thefpoint.x & 0 & 0 & 0 \\ 0 & thefpoint.y & 0 & 0 \\ 0 & 0 & thefpoint.z & 0 \\ 0 & 0 & 0 & 1 \end{bmatrix}$

void lti::geometricTransform::parameters::scale ( const tpoint< double > & thefPoint )

Set the scaling factor of the homogeneous matrix.

This is achieved multiplying the existing matrix with a resize matrix. If you use this function on an unit matrix you get the following matrix:

$\begin{bmatrix} thefpoint.x & 0 & 0 & 0 \\ 0 & thefpoint.y & 0 & 0 \\ 0 & 0 & 1 & 0 \\ 0 & 0 & 0 & 1 \end{bmatrix}$

void lti::geometricTransform::parameters::shift ( const tpoint3D< double > & thefPoint )

This function adds the point to the translation vector.

void lti::geometricTransform::parameters::shift ( const tpoint< double > & thefPoint )

This function adds the point to the translation vector.

(z component assumed 0)

virtual bool lti::geometricTransform::parameters::write	(	ioHandler &	handler,
		const bool	complete = `true`
	)			const `[virtual]`

Write the parameters in the given ioHandler.

Parameters:

	handler	the ioHandler to be used
	complete	if true (the default) the enclosing begin/end will be also written, otherwise only the data block will be written.
