The Topology ToolKit (TTK) is an open-source library and software collection for topological data analysis and visualization.
TTK can handle scalar data defined either on regular grids or
triangulations, in 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 time-varying scalar data: critical point tracking, nested tracking graphs;
· For high-dimensional / point cloud data: dimension reduction, persistence-based clustering;
· 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 visualization front end
ParaView. Thanks to ParaView, TTK supports a variety of input data

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
We have specifically developed it such that you can easily write your own data
analysis tools as TTK modules.
