Detailed Description

template<class Mesh>
struct OpenMesh::Decimater::CollapseInfoT< Mesh >

Stores information about a halfedge collapse.

The class stores information about a halfedge collapse. The most important information is v0v1, v1v0, v0, v1, vl, vr, which you can lookup in the following image:

Constructor & Destructor Documentation

CollapseInfoT()

template<class Mesh >

OpenMesh::Decimater::CollapseInfoT< Mesh >::CollapseInfoT ( Mesh &  _mesh, typename Mesh::HalfedgeHandle  _heh  )

inline

Initializing constructor.

Given a mesh and a halfedge handle of the halfedge to be collapsed all important information of a halfedge collapse will be stored.

Local configuration of halfedge collapse to be stored in CollapseInfoT:

vl
 *
/ \

/ \ / fl \ v0 ---—> v1 \ fr / \ / \ /

• vr

Parameters

_mesh	Reference to mesh
_heh	The halfedge (v0 -> v1) defining the collapse The direction of the halfedge defines the direction of the collapse, i.e. the from-vertex will be removed and the to-vertex remains.
