This repository contains the material for the TTK Online Example Database.
It is licensed under the Creative Commons Attribution 4.0 International License.
This repository has multiple purposes:
- Each entry is automatically tested by our continuous integration. At the moment, only code features which are used in ttk-data's state files are automatically tested upon code pull requests.
- Each entry is described in detail in the TTK Online Example Database, for novice users who want to get started with TTK and Python. Specifically, each entry contains a description of the use-case, a specification of the input/output, a screenshot, a ParaView state file, a Python script and links to the developer documentation.
