A C++ library for the representation of meshes with Combinatorial Maps

CGoGN is develop by the research team IGG of the ICube Laboratory of the University of Strasbourg It is now part of a most generic platform name GAIA (in a pole name Modelling & Simulation) which aim to treat most generic type of data, from analysis until Visualisation.

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:

Following this fundamental principle, our implementation also aims at:

You can jump here to read an introduction to meshes and combinatorial maps. Depending on your current understanding of this model and on the level on which you plan to use the library, you may or may not need to read it. So feel free to jump directly to the documentation.
