1.1 What you need to know:

The Topology ToolKit (TTK) is an open-source library and software collection for topological data analysis in scientific visualization.

Each TTK module consists two layers:

• base (your secrete garden):
  • Contains the heavy lifting of the module, i.e., algorithms, data structures, etc
  • This layer can be imagined as a standalone library that only exposes the functionality of the module via functions
  • The base layer should have as less dependencies as possible (especially VTK is not used at this layer)
• vtk (the common interface):
  • The sole purpose of the VTK layer is to unify data input/output, i.e., to make it possible to easily chain modules (base codes).
  • The VTK data model and pipeline infrastructure is build for that.
  • Specifically, the base code is wrapped by a vtk layer that
    • converts input vtkDataObjects and parameters into a format the corresponding base code can understand,
    • executes the base code with the converted data, and
    • creates output vtkDataObjects based on the results of the base code.
