Delynoi: an object-oriented C++ library for the generation of polygonal meshes

Alejandro Ortiz-Bernardin's picture

Free and open source C++ library for the generation of polygonal meshes on arbitrary domains, based on the constrained Voronoi diagram. It is the built-in polygonal mesh generator of the Veamy library.

  • The meshes are generated on arbitrary domains, created from user defined points. Domains have no restrictions on convexity.
  • It allows the inclusion of completely contained or intersecting holes, which are processed if required.
  • The meshes are generated from seed points, which can be read either directly from a text file, included one by one,
    or created from a number of generation rules included in the library. New generation rules can be easily included.
  • Meshes can be stored in OFF-style text files, or used directly in another program.
  • To generate the meshes, the library first computes the conforming Delaunay triangulation using Triangle; the triangulation
    is considered as a mesh that is left available for use if needed. Then, it computes the constrained Voronoi diagram.
