Please find below detailed instructions for the installation of TTK from sources, under
MacOS.<br><br>
TTK is also supported on other operating systems:<br>
·
<a href="installation-linux-sources.html">
Linux installation instructions</a> (default target platform);
<br>
·
<a href="installation-windows-sources.html">
Windows installation instructions</a>.<br><br>
If you are an advanced user and you do not wish to install ParaView (TTK's
main user interface), you
still
have the possibility to install TTK without ParaView support (although we
highly recommend to activate it).<br>
In that case, simply
download TTK as described in section 1, install the dependencies as detailed
in
section 2 and finally, directly jump to section 6 (<i>"Configuring, building
and installing TTK"</i>). <br>
Examples showing how to use TTK libraries from your
own VTK code can be found
<a target="new"
href="https://github.com/topology-tool-kit/ttk/tree/dev/examples/vtk-c%2B%2B"
>on this page</a>.<br><br>
If you are an advanced user and you do not even wish to install VTK, you still
have the possibility to install TTK without VTK support (although we
highly recommend to activate it).<br>
In that case, simply download TTK as described in section 1, install the
<b>optional</b> dependencies as detailed in
section 2 and finally, directly jump to section 6 (<i>"Configuring, building
and
installing TTK"</i>). <br>
Examples showing how to use TTK libraries from your own
C++ code can be found

>on this page</a>.<br>
<br>
<b>Most users will want to activate TTK's ParaView support.</b><br><br>
This page describes installing TTK 0.9.9 on MacOS, using Mojave 10.14.6 and
ParaView 5.8.1. The key differences from the linux installation involve how
ParaView is compiled, installing certain dependencies, and setting up some of
the paths for MacOS. The following assumes that the target is to compile with
MacOS clang and uses homebrew for dependencies, including python3<br><br>
Other versions of earlier software packages
may require slight variations in the installation procedure.
For earlier versions of both software packages, you may want to check out
previous versions of our installation notes for MacOS: <br>

with ParaView 5.6.1 on MacOS Mojave</a>.<br>
· <a href="installation-osx-0.9.7.html">TTK 0.9.7

with ParaView 5.4.1</a>.<br>
· <a href="installation-osx-0.9.2.html">TTK 0.9.2 with
ParaView 5.4.0</a>.<br>
<p><h3>1. Downloads</h3>
Note: The instructions for this step are identical to those on linux:<br><br>
TTK builds on top of <a href="http://www.paraview.org"
target="new">ParaView</a> for its main user interface. Thus, you will first
need to download
<a
href="https://www.paraview.org/paraview-downloads/download.php?submit=Download&version=v5.8&type=source&os=Sources&downloadFile=ParaView-v5.8.1.tar.gz"
target="new">
ParaView 5.8.1's source code</a>.
Note
that TTK plugins for ParaView will only work with a version of ParaView
compiled from source. Thus, if you already installed ParaView with a binary
copy, you may need to un-install it before proceeding.
Next, download TTK from our <a
href="downloads.html">download page</a>.
</p>
<p><h3>2. Installing the dependencies</h3>
<h4>a) Required Dependencies</h4>
Using <a href="https://brew.sh/">homebrew</a>, install:
<ul>
<li> cmake (tested with 3.15.2) </li>
<li> qt (tested with 5.13.0) </li>
<li> python (tested with 3.7.4)<br/>
Note: We use python3 instead of MacOS's default python2. To map the default executable for python, please add <code>export PATH="/usr/local/opt/python/libexec/bin/:$PATH"</code> to either your <code>~/.bashrc</code>, <code>~/.bash_profile</code>, or other shell startup script.</li>
<li> vtk 9<br/>
This required installing certain vtk dependencies, which do install
python2 (so take care), including:
<ul>
<li>pyqt (tested with version 5.10.1_1</li>
<li>sip (tested with version 4.19.8_12)</li>
</ul>
Installing vtk will also install hdf5 as a dependency (that ParaView can make use of).
</ul>
Altogether, this required the following sequence of commands:<br><br>
<code>$ brew install cmake qt python vtk</code><br><br>
<h4>b) Optional Dependencies</h4>
<h5>(i) ffmpeg:</h5>
Using homebrew, one can install optional packages for ParaView features with homebrew:
<ul>
<li> ffmpeg (tested with 4.1.4_1) </li>
</ul>
Using the command: <code>$ brew install ffmpeg</code><br><br>
<h5>(ii) OpenMP:</h5>
Using homebrew, one can also install OpenMP support for TTK with homebrew:
<ul>
<li> libomp (tested with 8.0.1)</li>
</ul>
Using the command: <code>$ brew install libomp</code><br><br>
<h5>(iii) OSPRay:</h5>
And, in addition, one can install OSPRay and it's dependencies using:
<ul>
<li> open-mpi (tested with 4.0.1_2):<br>
<code>$ brew install open-mpi</code> </li>
<li>Download and expand ospray-1.8.5.x86_64.macosx.tar.gz from <a href="http://www.ospray.org/getting_ospray.html">http://www.ospray.org/getting_ospray.html</a> (you will find it under <a href="https://github.com/ospray/OSPRay/releases">Old Releases</a>. Newer versions of ospray are not yet compatible with TTK 0.9.9's CMake structure), to install:
<ul>
<li>Copy lib/cmake and lib/libospray* to /opt/local/lib</li>
<li>Copy include/* to /opt/local/include</li>
<li>Copy scripts to /opt/local/share/OSPRay-1.8.5</li>
<li>Copy bin and doc to /Applications/OSPRay</li>
</ul>
You may need to create some of the destination directories before copying. The above steps manually do the work that the *.dmg file does.
</li>
<!--
<li>Download and expand ospray-1.8.5.x86_64 from <a href="http://www.ospray.org/getting_ospray.html">http://www.ospray.org/getting_ospray.html</a>, to install:
<ul>
<li>Copy the files in Applications to /Applications</li>
<li>Copy the files in opt to /opt, including local/include, local/lib, and local/share</li>
</ul>
This .dmg file does not manually copy anything, but rather just presents you with the files to copy on your own.
</li>
-->
<li>Download and unpack embree-3.5.2.x86_64.pkg from <a href="https://embree.github.io/downloads.html">https://embree.github.io/downloads.html</a> (this installs in /opt/local and /Applications).</li>
<li>Download and unpack tbb2019_20190605oss_mac.tgz from <a
href="https://github.com/01org/tbb/releases">https://github.com/01org/tbb/releases</a>. After expanding the .tgz, to install:
<ul>
<li>Copy lib/libtbb* to /opt/local/lib</li>
<li>Copy cmake/* to /opt/local/lib/cmake/tbb</li>
<li>Copy include/tbb to /opt/local/include</li>
</ul>
You may need to create some of the destination directories before copying.</li>
</ul>
After doing all of the above, you'll likely want to make sure that your command line knows about ospray/embree/tbb, the easy fix for this is to add <code>export DYLD_LIBRARY_PATH="/opt/local/lib"</code> to your <code>~/.bashrc</code>.<br><br>
<h5>(iv) TTK optional dependencies:</h5>
Finally, in order to enjoy the complete set of TTK features, we also recommend installing the following, optional TTK dependencies:
<ul>
<li><a target="new" href="http://eigen.tuxfamily.org/">eigen</a> (for scalar field design) tested with version 3.3.7 on homebrew:<br>
<code>$ brew install eigen</code></li>
<li><a target="new" href="https://www.graphviz.org/">graphviz</a> (for graph drawing features) tested with version 2.40.1_1 on homebrew:<br>
<code>$ brew install graphviz</code></li>
<li><a target="new" href="https://scikit-learn.org/stable/index.html">scikit-learn</a> for Python3 (for data reduction features, version 0.19.0 or later). Support is still experimental. We tested with version 0.21.3, installed for python3 with pip:<br>
<code>$ pip install -U scikit-learn</code></li>
<li><a target="new" href="https://github.com/yixuan/spectra/archive/v0.8.1.tar.gz">Spectra</a> (for the computation of the eigenfunctions of the Laplace-Beltrami operator) tested with version 0.8.1 and <a href="https://spectralib.org/">installed from source (see instructions)</a>.</li>
<li><a href="https://www.sqlite.org/" target="new">sqlite</a> (for cinema query features), tested with version 3.29.0 on homebrew:<br>
<code>$ brew install sqlite</code></li>
<li><a href="https://github.com/LLNL/zfp/archive/master.zip" target="new">ZFP</a> (for advanced compression support, version 0.5.4 or later) tested with version 0.5.5 and <a href="https://github.com/LLNL/zfp">installed from source (see instructions)</a>,</li>
<li><a href="https://zlib.net/" target="new">zlib</a> (for further compression support) tested with version 1.2.11 on homebrew:<br>
<code>$ brew install zlib</code></li>
</ul>
</p>
<p><h3>3. Preparing the sources</h3>
Note: The instructions for this step are identical to those on linux:<br><br>
Move the tarballs to a working directory (for instance called
<code>~/ttk</code>) and decompress them by entering the following commands in
a terminal (this assumes that you downloaded the tarballs to the
<code>~/Downloads</code> directory):<br><br>
<code>$ mkdir ~/ttk</code><br>
<code>$ mv ~/Downloads/ParaView-v5.8.1.tar.gz ~/ttk/</code><br>
<code>$ mv ~/Downloads/ttk-0.9.9.tar.gz ~/ttk/</code><br>
<code>$ cd ~/ttk</code><br>
<code>$ tar xvzf ParaView-v5.8.1.tar.gz</code><br>
<code>$ tar xvzf ttk-0.9.9.tar.gz</code><br><br>
You can delete the tarballs after the source trees have been decompressed by
entering the following commands:<br><br>
<code>$ rm ParaView-v5.8.1.tar.gz</code><br>
<code>$ rm ttk-0.9.9.tar.gz</code><br><br>
</p>
<p><h3>4. Patching the ParaView source tree</h3>
Note: The instructions for this step are identical to those on linux:<br><br>
In order to enjoy the complete set of TTK features, we
recommend at this stage to patch the ParaView source tree.
This step is
optional.
To proceed, go to
the patch directory and apply it as follows:<br><br>
<code>$ cd ~/ttk/ttk-0.9.9/paraview/patch</code><br>
<code>$ ./patch-paraview-5.8.1.sh ~/ttk/ParaView-v5.8.1/</code><br><br>
</p>
<p><h3>5. Configuring, building and installing ParaView</h3>
<h4>a) Configuration</h4>
To enter the configuration menu of ParaView's build, enter the following
commands:<br><br>
<code>$ cd ~/ttk/ParaView-v5.8.1/</code><br>
<code>$ mkdir build</code><br>
<code>$ cd build</code><br>
<code>$ ccmake ..</code> (on homebrew cmake there is no <code>cmake-gui</code>,
although you can install this separately from <a
href="https://cmake.org/download/">https://cmake.org/download/</a>)<br><br>
Then, press 'c' to configure and we'll edit some CMake flags (you may
have to press 't' to find them):<br>
<code> · CMAKE_BUILD_TYPE=Release</code><br>
<code> · PARAVIEW_USE_PYTHON=ON</code><br>
<code> · PARAVIEW_PYTHON_VERSION=3</code><br>
<code> · VTK_SMP_IMPLEMENTATION_TYPE=Sequential</code> (the default)<br>
<br>
You can also enable optional pieces, including:
<h5>(i) ffmpeg:</h5>
<code> · PARAVIEW_ENABLE_FFMPEG=ON</code><br>
<br>
<h5>(ii) OpenMP as the SMP implementation:</h5>
At this time, we do not recommend building ParaView 5.8.1 with OpenMP,
even though TTK can take advantage of OpenMP for some of its features.
For parallelism in ParaView, please use TBB.<br>
<br>
<!--
<code> · VTK_SMP_IMPLEMENTATION_TYPE=OpenMP</code> (changed from the default
"Sequential")<br>
Note, after hitting 'c' to configure, cmake will require you to set additional flags, e.g. <code>OpenMP_CXX_FLAGS</code>, <code>OpenMP_CXX_LIBRARY</code>, <code>OpenMP_C_FLAGS</code>, <code>OpenMP_C_LIBRARY</code>. If you are interested in using OpenMP, we do not recommend using ccmake, but instead use the cmake command below.<br>
<br>
-->
<h5>(iii) OSPRay (which requires TBB):</h5>
<code> · PARAVIEW_USE_OSPRAY=ON</code><br>
<code> · OSPRAY_INSTALL_DIR=/opt/local/lib</code> (this variable will show up and need to be set after setting <code>PARAVIEW_USE_OSPRAY=ON</code> and hitting 'c' to reconfigure.)<br>
<br>
<h5>(iv) TBB as the SMP implementation (which isn't necessary, but if you do not want to use OpenMP and you've installed OSPRay, then you have TBB too):</h5>
<code> · VTK_SMP_IMPLEMENTATION_TYPE=TBB</code> (changed from the default
"Sequential")<br>
Note, hitting 'c' to configure, cmake will also set <code>VTKm_ENABLE_TBB=ON</code> and should find all include dirs and libraries for TBB in /opt/local if you've installed it correctly.<br>
<br>
After specifying the above options, press 'c' to configure (wait a minute) and then press 't' for advanced mode to double check the above paths and/or fill in any flags that did not appear the first time. You may need to press 'c' again, which fills in some more paths. Once cmake is finished configuring, you should finalize everything by pressing 'g' to generate and exit.<br><br>
<br><br>
If you prefer to just run <code>cmake</code> as opposed to <code>ccmake</code> or <code>cmake-gui</code>, the following summarizes five possible installations:
<h5>Basic (No Optional Dependencies)</h5>
<code>$ cmake \<br>
-DCMAKE_BUILD_TYPE=Release \<br>
-DPARAVIEW_ENABLE_PYTHON=ON \<br>
-DVTK_PYTHON_VERSION=3 \<br>
..
</code><br>
<h5>(i) Sequential + ffmpeg</h5>
<code>$ cmake \<br>
-DCMAKE_BUILD_TYPE=Release \<br>
-DPARAVIEW_ENABLE_PYTHON=ON \<br>
-DVTK_PYTHON_VERSION=3 \<br>
-DPARAVIEW_ENABLE_FFMPEG=ON \<br>
-DVTK_SMP_IMPLEMENTATION_TYPE=Sequential \<br>
..
</code><br>
<!--
<h5>(iii) OpenMP + ffmpeg</h5>
<code>$ cmake \<br>
-DCMAKE_BUILD_TYPE=Release \<br>
-DPARAVIEW_ENABLE_PYTHON=ON \<br>
-DPARAVIEW_ENABLE_FFMPEG=ON \<br>
-DVTK_SMP_IMPLEMENTATION_TYPE=OpenMP \<br>
-DOpenMP_CXX_FLAGS="-Xclang -fopenmp -I/usr/local/opt/libomp/include" \<br>
-DOpenMP_CXX_LIB_NAMES=omp \<br>
-DOpenMP_C_FLAGS="-Xclang -fopenmp -I/usr/local/opt/libomp/include" \<br>
-DOpenMP_C_LIB_NAMES=omp \<br>
-DOpenMP_omp_LIBRARY=/usr/local/opt/libomp/lib/libomp.dylib \<br>
..
</code><br>
-->
<h5>(i),(iii),(iv) TBB + ffmpeg + OSPRay</h5>
<code>$ cmake \<br>
-DCMAKE_BUILD_TYPE=Release \<br>
-DPARAVIEW_ENABLE_PYTHON=ON \<br>
-DVTK_PYTHON_VERSION=3 \<br>
-DPARAVIEW_ENABLE_FFMPEG=ON \<br>
-DVTK_SMP_IMPLEMENTATION_TYPE=TBB \<br>
-DPARAVIEW_USE_OSPRAY=ON \<br>
-DOSPRAY_INSTALL_DIR=/opt/local/lib \<br>
..
</code><br>
<!--
<h5>(v) OpenMP + ffmpeg + OSPRay</h5>
<code>$ cmake \<br>
-DCMAKE_BUILD_TYPE=Release \<br>
-DPARAVIEW_ENABLE_PYTHON=ON \<br>
-DPARAVIEW_ENABLE_FFMPEG=ON \<br>
-DVTK_SMP_IMPLEMENTATION_TYPE=OpenMP \<br>
-DOpenMP_CXX_FLAGS="-Xclang -fopenmp -I/usr/local/opt/libomp/include" \<br>
-DOpenMP_CXX_LIB_NAMES=omp \<br>
-DOpenMP_C_FLAGS="-Xclang -fopenmp -I/usr/local/opt/libomp/include" \<br>
-DOpenMP_C_LIB_NAMES=omp \<br>
-DOpenMP_omp_LIBRARY=/usr/local/opt/libomp/lib/libomp.dylib \<br>
-DPARAVIEW_USE_OSPRAY=ON \<br>
-DOSPRAY_INSTALL_DIR=/opt/local/lib \<br>
..
</code><br>
-->
<br><br>
<h4>b) Build</h4>
Now you can start the compilation process by entering the following command,
where <code>N</code> is the number of available cores on your system (this will
take a <b>LONG</b> time):<br><br>
<code>$ make -jN</code><br><br>
<h4>c) Installation</h4>
Once the build is finished, we recommend that you do <strong>not</strong> use <code>make install</code>. We will work directly in the build directory for the source tree instead of trying to package up a MacOS .app file in <code>/Applications</code>. <br><br>
Finally, to enable ParaView and pvpython to find the TTK plugins we will build, we recommend setting the environment variable <code>PV_PLUGIN_PATH</code> to be the location where you choose to install TTK. Note that this is different from past installations where we manually installed TTK in the build directory. Instead, these instructions will assume that you will install TTK's plugins in <code>/usr/local/lib/plugins</code> (the cmake variable <code>TTK_INSTALL_PLUGIN_DIR</code> will be set accordingly in the next step).<br><br>
To set this environment variable permanently, we recommend editing whatever file you normally configure these in (e.g. <code>~/.bash_profile</code>) and adding the line:<br><br>
<code>export PV_PLUGIN_PATH="/usr/local/lib/plugins"</code><br><br>
Note that, by default, our installation of ParaView will search for plugins in <code>~/ttk/ParaView-v5.8.1/build/bin/paraview.app/Contents/MacOS/plugins</code>. And, by default, our installation of pvpython will search fo plugins in <code>~/ttk/ParaView-v5.8.1/build/bin/plugins</code>. Setting <code>PV_PLUGIN_PATH</code> overrides this so that both can search for TTK in a common location. Users may want to choose to use a different location that <code>/usr/local/lib/plugins</code>, although this path is consistent with where the Linux installation of TTK installs them.<br><br>
For more information, see <a href="https://www.paraview.org/Wiki/ParaView/Plugin_HowTo#Using_Plugins">https://www.paraview.org/Wiki/ParaView/Plugin_HowTo#Using_Plugins</a>.
</p>
<p>
<h3>6. Configuring, building and installing TTK</h3>
<h4><a name="ttkConfig">a)</a> Configuration</h4>
To enter the configuration menu of TTK's build, enter the following
commands:<br><br>
<code>$ cd ~/ttk/ttk-0.9.9/</code><br>
<code>$ mkdir ttk_install</code> (for installing standalone apps)<br>
<code>$ mkdir build</code><br>
<code>$ cd build</code><br>
<code>$ ccmake ..</code><br><br>
The configuration window opens. Press 'c' to configure, and you'll see that it
cannot yet find ParaView. First, we'll fix this:<br><br>
<code> · ParaView_DIR=~/ttk/ParaView-v5.8.1/build/</code><br><br>
Press 'c' again to configure (you can ignore the warnings). Also note that
<code>VTK_DIR</code> should automatically be set to the homebrew installation
of VTK (<code>/usr/local/lib/cmake/vtk-8.2</code>). Next, change:<br><br>
<code> · CMAKE_BUILD_TYPE=Release</code><br>
<code> · CMAKE_INSTALL_PREFIX=~/ttk/ttk-0.9.9/ttk_install</code
><br>
(this is where standalone apps and
other TTK components are installed)<br>
<code> · TTK_INSTALL_PLUGIN_DIR=/usr/local/lib/plugins</code><br>
(this is where ParaView plugins are installed)<br>
<code> · PYTHON_NUMPY_INCLUDE_DIR=/usr/local/lib/python3.7/site-packages/numpy/core/include</code><br>
(this should be where
homebrew's python3 installs numpy, which our CMake script does not yet
detect)<br>
<br>
If you are an advanced user and you do not wish to activate TTK's ParaView
support, set the CMake variable <code>TTK_BUILD_PARAVIEW_PLUGINS</code> to
<code>OFF</code>.
Examples showing how to use TTK libraries from your
own VTK code can be found
<a target="new"
href="https://github.com/topology-tool-kit/ttk/tree/dev/examples/vtk-c%2B%2B"
>on this page</a>.<br>
Press 'c' to reconfigure (again takes a few seconds) and then press 'g' to
generate.<br><br>
If you are an advanced user and you do not even wish to activate TTK's VTK
support, set the CMake variable
<code>TTK_BUILD_VTK_WRAPPERS</code> to <code>OFF</code>.
Examples showing how to use TTK libraries from your own
C++ code can be found
<a target="new"
href="https://github.com/topology-tool-kit/ttk/tree/dev/examples/c%2B%2B"
>on this page</a>.<br>
Press 'c' to reconfigure (again takes a few seconds) and then press 'g' to
generate.<br><br>
<!--Note that you can enable building certain portions of TTK at this time
as well by switching the flags associated with each (e.g.
TTK_BUILD_PARAVIEW_PLUGINS, TTK_BUILD_STANDALONE_APPS, etc.). -->
Note that if you are working with optional dependencies, you may also need to set certain CMake variables, including:
<ul>
<li>eigen should be automatically detected.</li>
<li>graphviz should be automatically detected.</li>
<li>scikit-learn is disabled by default on MacOS, but can be enabled by setting <code>TTK_ENABLE_SCIKIT_LEARN</code> to <code>ON</code>.</li>
<li>Depending on where you installed it, to enable Spectra set the variable <code>SPECTRA_INCLUDE_DIR</code> to the <code>include</code> subdirectory of where you installed Spectra.</li>
<li>sqlite should be automatically detected.</li>
<li>Depending on where you installed it, you may have to set <code>ZFP_DIR</code> to the directory where you built ZFP.</li>
<li>zlib should be automatically detected.</li>
</ul>
<br>
Finally, if you'd like to try out OpenMP (again, experimental), you would
add:<br>
<code> · TTK_ENABLE_OPENMP=ON</code><br>
<code> · OpenMP_CXX_FLAGS="-Xclang -fopenmp -I/usr/local/opt/libomp/include"</code><br>
<code> · OpenMP_CXX_LIB_NAMES=omp</code><br>
<code> · OpenMP_omp_LIBRARY=/usr/local/opt/libomp/lib/libomp.dylib</code><br>
<br>
Press 'c' to reconfigure (again takes a few seconds) and then press 'g' to
generate.<br><br>
If you prefer to just run <code>cmake</code> as opposed to <code>ccmake</code>
or <code>cmake-gui</code>, the following summarizes the two possible
installations:
<h5>(i) Basic TTK</h5>
<code>$ cmake \<br>
-DParaView_DIR=~/ttk/ParaView-v5.8.1/build/ \<br>
-DCMAKE_BUILD_TYPE=Release \<br>
-DCMAKE_INSTALL_PREFIX=~/ttk/ttk-0.9.9/ttk_install \<br>
-DTTK_INSTALL_PLUGIN_DIR=/usr/local/lib/plugins \<br>
-DPYTHON_NUMPY_INCLUDE_DIR=/usr/local/lib/python3.7/site-packages/numpy/core/include \<br>
..
</code><br>
<h5>(ii) TTK + OpenMP</h5>
<code>$ cmake \<br>
-DParaView_DIR=~/ttk/ParaView-v5.8.1/build/ \<br>
-DCMAKE_BUILD_TYPE=Release \<br>
-DCMAKE_INSTALL_PREFIX=~/ttk/ttk-0.9.9/ttk_install \<br>
-DTTK_INSTALL_PLUGIN_DIR=/usr/local/lib/plugins \<br>
-DPYTHON_NUMPY_INCLUDE_DIR=/usr/local/lib/python3.7/site-packages/numpy/core/include \<br>
-DTTK_ENABLE_OPENMP=ON \<br>
-DOpenMP_CXX_FLAGS="-Xclang -fopenmp -I/usr/local/opt/libomp/include" \<br>
-DOpenMP_CXX_LIB_NAMES=omp \<br>
-DOpenMP_omp_LIBRARY=/usr/local/opt/libomp/lib/libomp.dylib \<br>
..
</code><br>
<br><br>
<h4>b) Build</h4>
Now you can start the compilation process by entering the following command,
where <code>N</code> is the number of available cores on your system:<br><br>
<code>$ make -jN</code><br><br>
<h4>c) Installation</h4>
Once the build is finished, enter the following command to install your build
of TTK into your ParaView installation:<br><br>
<code>$ make install</code><br><br>
Note that in addition to copying the TTK plugins to your ParaView installation
(<code>TTK_INSTALL_PLUGIN_DIR</code>), the above command also installed a
collection of standalone TTK programs to <code>CMAKE_INSTALL_PREFIX</code>.
These can be used outside of ParaView, either as command line tools or
VTK-based graphical user interfaces. To list them:<br><br>
<code>$ ls CMAKE_INSTALL_PREFIX/bin/*Cmd</code><br>
<code>$ ls CMAKE_INSTALL_PREFIX/bin/*Gui</code><br><br>
Replacing <code>CMAKE_INSTALL_PREFIX</code> with what we used above.<br><br>
Finally, to make sure the example data files are included in the right path,
you have to manually copy the example data into the ParaView .app as
well:<br><br>
<code>$ cd ~/ttk/ttk-0.9.9/paraview/patch/data</code><br>
<code>$ mkdir -p ~/ttk/ParaView-v5.8.1/build/bin/paraview.app/Contents/share/paraview-5.6/examples</code><br>
<code>$ cp * ~/ttk/ParaView-v5.8.1/build/bin/paraview.app/Contents/share/paraview-5.6/examples</code><br>
<br>
</p>
<p>
<h3>7. Checking your TTK installation</h3>
If you applied all the above steps successfully (including step 4), you can now
open a terminal and type the following command to load your TTK-patched
ParaView:<br><br>
<code>$ cd
~/ttk/ParaView-v5.8.1/build/bin/paraview.app/Contents/MacOS/</code><br><br>
<code>$ ./paraview</code><br><br>
At this point, everything from the standard installation procedure should be accessible. Congrats!
