CGoGN is a geometric modeling C++ library that provides an efficient implementation of combinatorial maps.
One of the fundamental idea of topological models is the strong separation between:

  • the description of the topology of the mesh (the cells and their adjacency relationships)
  • the space in which the cells are embedded (attributes associated to the cells)

Following this fundamental principle, our implementation also aims at:

  • efficiency (more contiguous tables, less pointers)
  • low memory consumption
  • genericity (models, dimensions)
  • ease of use
