To be able to run code from this repository, install TTK using these guidlelines. This code has been tested with TTK 0.96 on Ubuntu 16.04/MacOS High Sierra.

TTK provides the ability to visualize and analyse scalar fields. However, analysing time-varying data by repeating the same tasks over and over again, can be tedious with TTK.

This repository provides code to automate tasks in TTK:

• Display scalar field
• Divide the domain
• Compute persistence diagram
• Simplify scalar field using persistence diagram
• Display critical points
• Compute Merge Trees
• Compute bottleneck/wasserstein distances
• Vertex Segmentation based on Merge/Contour Trees
• Face Segmentation based on Merge Trees

To run the code:

• Place your data within a folder titled 'input'
• For details on other folders you may want to create, look into helper.py and compute.py
• Then execute, python run.py
• To run TTK parallelly, execute python test.py <number of files> <number of cores>
