Detailed Description

template<typename MeshT>
class OpenMesh::Decimater::ModBaseT< MeshT >

Base class for all decimation modules.

Each module has to implement this interface. To build your own module you have to

  1. derive from this class.
  2. create the basic settings with DECIMATING_MODULE().
  3. override collapse_priority(), if necessary.
  4. override initialize(), if necessary.
  5. override postprocess_collapse(), if necessary.

A module has two major working modes:

  1. binary mode
  2. non-binary mode

In the binary mode collapse_priority() checks a constraint and returns LEGAL_COLLAPSE or ILLEGAL_COLLAPSE.

In the non-binary mode the module computes a float error value in the range [0, inf) and returns it. In the case a constraint has been set, e.g. the error must be lower than a upper bound, and the constraint is violated, collapse_priority() must return ILLEGAL_COLLAPSE.

Member Function Documentation

◆ collapse_priority()

template<typename MeshT>
virtual float OpenMesh::Decimater::ModBaseT< MeshT >::collapse_priority ( const CollapseInfoT< MeshT > &  )
inlinevirtual

Return collapse priority.

In the binary mode collapse_priority() checks a constraint and returns LEGAL_COLLAPSE or ILLEGAL_COLLAPSE.

In the non-binary mode the module computes a float error value in the range [0, inf) and returns it. In the case a constraint has been set, e.g. the error must be lower than a upper bound, and the constraint is violated, collapse_priority() must return ILLEGAL_COLLAPSE.

Returns
Collapse priority in the range [0,inf), LEGAL_COLLAPSE or ILLEGAL_COLLAPSE.

◆ postprocess_collapse()

template<typename MeshT>
virtual void OpenMesh::Decimater::ModBaseT< MeshT >::postprocess_collapse ( const CollapseInfoT< MeshT > &  )
inlinevirtual

After _from_vh has been collapsed into _to_vh, this method will be called.

Reimplemented in OpenMesh::Decimater::ModNormalDeviationT< MeshT >, OpenMesh::Decimater::ModNormalDeviationT< TriMesh >, ModBalancerT< D >, OpenMesh::Decimater::ModQuadricT< MeshT >, OpenMesh::Decimater::ModQuadricT< D >, OpenMesh::Decimater::ModQuadricT< TriMesh >, OpenMesh::Decimater::ModProgMeshT< MeshT >, OpenMesh::Decimater::ModHausdorffT< MeshT >, OpenMesh::Decimater::ModHausdorffT< TriMesh >, OpenMesh::Decimater::ModIndependentSetsT< MeshT >, and OpenMesh::Decimater::ModIndependentSetsT< TriMesh >.

◆ preprocess_collapse()

template<typename MeshT>
virtual void OpenMesh::Decimater::ModBaseT< MeshT >::preprocess_collapse ( const CollapseInfoT< MeshT > &  )
inlinevirtual

Before _from_vh has been collapsed into _to_vh, this method will be called.

Reimplemented in OpenMesh::Decimater::ModAspectRatioT< MeshT >, and OpenMesh::Decimater::ModAspectRatioT< TriMesh >.

Definition at line 251 of file ModBaseT.hh.

◆ set_error_tolerance_factor()

template<typename MeshT>
virtual void OpenMesh::Decimater::ModBaseT< MeshT >::set_error_tolerance_factor ( double  _factor)
inlinevirtual

This provides a function that allows the setting of a percentage of the original contraint.

Note that the module might need to be re-initialized again after setting the percentage

Parameters
_factorhas to be in the closed interval between 0.0 and 1.0
