The Gudhi library (Geometric Understanding in Higher Dimensions) is a generic C++ library for
topological analysis of high-dimensional data whose goal is to provide robust, efficient, flexible and easy to use
implementations of
state-of-the-art algorithms and data structures for computational topology.
The current release of the library allows to use several data-structures for simplicial complexes :
simplex tree, Hasse diagram or skeleton-blocker. Several operations can then be done on top of these
representations such as persistent homology computation or simplification.
All data-structures are generic and several of their aspects (such as stored elements, policies)
can be parameterized via template classes.
We refer to
\cite gudhilibrary_ICMS14
for a detailed description of the design of the library.
\section compiling Compiling
The library uses c++11 and requires Boost with version 1.48.0 or more recent : http://www.boost.org/.
It is a multiplaform library and compiles on Linux, Mac OSX and Visual Studio 2013.
\subsection gmp GMP:
The multi-field persistent homology algorithm requires GMP which is a free library for arbitrary-precision
arithmetic, operating on signed integers, rational numbers, and floating point numbers
The following examples require The GNU Multiple Precision Arithmetic Library (GMP) http://gmplib.org/
and will not be built if GMP is not installed:
- Persistent_cohomology/rips_multifield_persistence
- Simplex_tree/simplex_tree_from_alpha_shapes_3
Having GMP version 4.2 or higher installed is recommended. This library can be obtained from http://gmplib.org/
\subsection cgal CGAL:
CGAL is a C++ library which provides easy access to efficient and reliable geometric algorithms.
The following example requires CGAL https://www.cgal.org/ and will not be built if CGAL is not installed:
- Simplex_tree/simplex_tree_from_alpha_shapes_3
Having CGAL version 4.4 or higher installed is recommended. The procedure to install this library according to
your operating system is detailed here http://doc.cgal.org/latest/Manual/installation.html
\section demos Demos and Examples
To build the library, run the following in a terminal:
\verbatim
cd /path-to-gudhi/
mkdir build
cd build/
cmake -DCMAKE_BUILD_TYPE=Release ..
make
\endverbatim
