The Topology ToolKit (TTK) is an open-source library and software collection for topological data analysis in scientific visualization.
TTK can handle scalar data defined either on regular grids or
triangulations, either in 2D or in 3D. 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, Morse-Smale complexes, topological simplification;
· 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;
· For high-dimensional / point cloud data: dimension reduction;
· and more!
If you need to robustly analyze your acquired or simulated scientific 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.
