The Topology ToolKit (TTK) is an open-source library and software
collection for topological data analysis and visualization.
> Citing TTK
TTK can handle scalar data defined either on regular grids or
triangulations, in 1D, 2D, 3D, or more. It provides a substantial collection of
generic, efficient and robust implementations of key algorithms in
topological data analysis. It includes:
· For scalar data: critical points, integral lines,
persistence diagrams,
persistence curves, merge trees, contour trees, Reeb graphs,
Morse-Smale complexes, topological simplification, topology-aware compression, harmonic design;
· For bivariate scalar data: fibers, fiber surfaces,
continuous scatterplots, Jacobi sets, Reeb spaces;
· For uncertain scalar data: mandatory critical points;
· For ensemble scalar data:
Bottleneck and Wasserstein distances between persistence diagrams (exact Munkres-based computation or fast Auction-based approximation), Wasserstein barycenters and clusters of persistence diagrams (fast progressive algorithms) and merge trees,
principal geodesic analysis of persistence diagrams and merge trees,
distance matrices (Lp norm, Wasserstein distances), contour tree alignment;
· For time-varying scalar data: critical point tracking, nested tracking graphs;
· For high-dimensional / point cloud data: dimension reduction, persistence-based clustering, persistent cycle extraction;
· and more!
If you need to robustly analyze your
data, you may want to use TTK.

TTK makes topological data analysis accessible to end users
thanks to easy-to-use plugins for the data analysis and visualization application
ParaView. Thanks to ParaView, TTK supports a variety of input data
formats.

TTK is written in C++ but comes with a variety of bindings
(VTK/C++, Python) and standalone command-line programs. It is modular and easy
to extend.
We have specifically developed it such that you can easily write your own data
analysis tools as TTK modules.
