## Classes

- [HalfEdge](https://developer.rhino3d.com/api/gh2/type/grasshopper2.geometry.halfedges.halfedge.md): Represents a halfedge in the half-edge mesh data structure. Derived from Plankton, (c) 2013 Daniel Piker and Will Pearson, licensed LGPL v3 or later.
- [HalfEdgeFace](https://developer.rhino3d.com/api/gh2/type/grasshopper2.geometry.halfedges.halfedgeface.md): Represents a face in the half-edge mesh data structure. Derived from Plankton, (c) 2013 Daniel Piker and Will Pearson, licensed LGPL v3 or later.
- [HalfEdgeFaceList](https://developer.rhino3d.com/api/gh2/type/grasshopper2.geometry.halfedges.halfedgefacelist.md): Provides access to the faces and [HalfEdgeFace](https://developer.rhino3d.com/api/gh2/type/grasshopper2.geometry.halfedges.halfedgeface.md) related functionality of a Mesh.
