<h3><a name="overview">1.</a> Global overview of TTK</h3>
This talk gives a global overview of TTK.
After introducing the main concepts behind TTK's usage, we demo how to use it with simple examples in ParaView and Python. Then, we present an overview of TTK's capabilities, going from simple critical point extraction to more advanced features (Reeb graphs, Morse-Smale complexes, distances and barycenters of persistence diagrams, etc) as well as TTK's current capabilities for processing point cloud data.<br><br>

<h3><a name="installation">2.</a> TTK installation</h3>
This video shows how to install TTK on a fresh new install of Ubuntu Linux
16.10.

<b>Update:</b>
TTK is now officially integrated in ParaView.
Please see our <a href="installation.html" target="new">installation page</a>
to discover the most recent and simplest installation procedures.

<h3><a name="usage">3.</a> TTK in action!</h3>
In the following, we assume that you successfully installed TTK
(see the above <a href="#installation">video</a> and our <a
href="installation.html">installation</a> page). We will also assume that you
downloaded the TTK data tarball from our <a href="downloads.html">download</a>
page (for instance, into your <code>~/Downloads/</code> directory). From there,
enter the following commands under Linux (omit the <code>$</code>
character) to decompress the data tarball:<br><br>
<code>$ mkdir ~/ttk</code><br>
<code>$ mv ~/Downloads/ttk-data-1.3.0.tar.gz ~/ttk/</code><br>
<code>$ cd ~/ttk</code><br>
<code>$ tar xvzf ttk-data-1.3.0.tar.gz</code><br>
<code>$ rm ttk-data-1.3.0.tar.gz</code><br><br>
You can now proceed with the following videos to see how to reproduce the
examples shown in the gallery section with the example data-sets you have just
de-compressed.
<br><br>
<b>Note to Python users</b>
<br>
Note that, for each of the following examples, once in ParaView, you have the possibility to export the example into a python script (that you can later edit according to your own needs) by clicking on <code>File</code>, then <code>Save State...</code> and by selecting the <code>Python state file (*.py)</code> extension as described in the

<b>Update:</b>
as of version 0.9.6, there is no need to check the box "UseInputOffsetField".
Input offsets are now automatically retrieved from the data, if present. To
force the usage of a specific field as vertex offset (advanced usage), check
the box "ForceInputOffsetField".
<br>
<b>Update:</b>
as of version 0.9.3, the TTK module "Contour Forests" is marked as
deprecated, in favor of a newer module, "Merge and Contour Tree (FTM)",
implementing a recently introduced algorithm using
task-based Fibonacci heaps. Performances should be greatly improved.
When using this module, to smooth
the contour tree skeleton, please use the "Geometry Smoother" module on the
"Skeleton Arcs" output and check the box "Use Input Mask Field" to constrain
the location of the skeleton critical nodes.

<b>Update:</b>
as of version 1.3.0, the TTK module "RangePolygon" is marked as
deprecated, in favor of built-in ParaView filters. Instead, please use the filter "PolyLineSource" to create your polygon on top of the Continuous Scatter Plot (CFP). Next, to map the input bivariate data to your polygon, use the filter "ResampleWithDataset" (with the CSP as a source, and the polygon as a target). Finally, apply the filter "Tetrahedralize", to transform the polygon into a simplicial representation. At this point, the output of "Tetrahedralize" is a valid polygon input for the TTK module "FiberSurface" (and can fully replace the deprecated "RangePolygon").
