## 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

template<class Mesh >

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

Initializing constructor.

Local configuration of halfedge collapse to be stored in CollapseInfoT:

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

Parameters

  _mesh | Mesh source
  _heh | Halfedge to 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.

vl

- / \ / \ / fl \ v0 *---—>* v1 \ fr / \ / \ /
- vr

Parameters

  _mesh | Reference to mesh
  _heh | The halfedge (v0 -> v1) defining the collapse
