math/openmesh 11.0.0 DragonFly

OpenMesh is a generic and efficient data structure for representing and manipulating polygonal meshes.

The main features of the underlying data structure are: * No restriction to triangles meshes, handle general polygonal meshes. * Explicit representation of vertices, halfedges, edges, and faces. * Efficient access to the one-ring neighborhood of a vertex. * Ability to handle non-manifold vertices (like two faces meeting in only one vertex).
