Constructor & Destructor Documentation

template<class Mesh>

OpenMesh::Smoother::SmootherT< Mesh >::SmootherT

(

Mesh &

_mesh

)

constructor & destructor

Parameters

_mesh

Reference a triangle or poly mesh

Definition at line 78 of file SmootherT.cc.

Member Function Documentation

template<class Mesh >

void OpenMesh::Smoother::SmootherT< Mesh >::disable_local_error_check

(

)

Disable error control of the smoother.

This function disables the error control of the smoother.

Definition at line 295 of file SmootherT.cc.

template<class Mesh >

void OpenMesh::Smoother::SmootherT< Mesh >::initialize	(	Component	_comp,
		Continuity	_cont
	)

Initialize smoother

Parameters

_comp	Determine component to smooth
_cont	Determine Continuity

Definition at line 127 of file SmootherT.cc.

template<class Mesh >

void OpenMesh::Smoother::SmootherT< Mesh >::set_absolute_local_error

(

Scalar

_err

)

Set local error as an absolute value.

Set the maximal error tolerance of the smoother to the given value.

Parameters

_err	Maximal error

Definition at line 283 of file SmootherT.cc.

template<class Mesh >

void OpenMesh::Smoother::SmootherT< Mesh >::set_active_vertices ( )

private

Find active vertices. Resets tagged status !

This function recomputes the set of active vertices, which will be touched by the smoother. If nothing on the mesh is selected, all vertices which are not locked, feature or boundary will be marked as active and moved by the smoother. If vertices are selected, than only the selected ones, excluding the locked, feature and boundary vertices will be moved.

The function is called first when running the smoother.

Definition at line 157 of file SmootherT.cc.

template<class Mesh >

void OpenMesh::Smoother::SmootherT< Mesh >::set_relative_local_error

(

Scalar

_err

)

Set local error relative to bounding box.

This function sets a maximal error tolerance for the smoother as a fraction of the bounding box of the mesh. First the bounding box diagonal is computed. Then the error is set as the length of the diagonal multiplied with the given factor.

Parameters

_err	Factor scaling the bounding box diagonal

Definition at line 253 of file SmootherT.cc.

template<class Mesh>

void OpenMesh::Smoother::SmootherT< Mesh >::skip_features ( bool  _state )

inline

enable or disable feature handling

This function can be used to control if features on the mesh should be preserved. If enabled, the smoother will keep features and does not modify them. Features can be set via OpenMesh status flags (request status and set primitives as features). Feature flag can be set for vertices edges and faces.

Parameters

_state

true : If features are selected on the mesh, they will be left unmodified false : Features will be ignored
