## Member Enumeration Documentation

## ◆ Component

template<class Mesh>

enum OpenMesh::Smoother::SmootherT::Component

Enumerator
Tangential | Smooth tangential direction.
Normal | Smooth normal direction.
Tangential_and_Normal | Smooth tangential and normal direction.

## Constructor & Destructor Documentation

## ◆ SmootherT()

template<class Mesh>

OpenMesh::Smoother::SmootherT< Mesh >::SmootherT | ( | Mesh & | _mesh | ) |

constructor & destructor

Parameters

  _mesh | Reference a triangle or poly mesh

## Member Function Documentation

## ◆ disable_local_error_check()

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.

## ◆ initialize()

template<class Mesh >

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

Initialize smoother.

Parameters

  _comp | Determine component to smooth
  _cont | Determine Continuity

## ◆ set_absolute_local_error()

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

## ◆ set_relative_local_error()

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

## ◆ skip_features()

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
