OpenMesh.Tools.Decimater.CollapseInfoT

struct CollapseInfoT (Mesh);

\file CollapseInfoT .hh Provides data class CollapseInfoT for storing all information about a halfedge collapse.

Stores information about a halfedge collapse.

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

CollapseInfoT opCall (Mesh _mesh, Mesh.HalfedgeHandle _heh);

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. \param mesh Mesh source \param 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.
