About
-----

`VTK (The Visualization Toolkit) <https://vtk.org/>`_ is an open-source software system for 3D computer graphics, image processing, and visualization. It is widely used in scientific computing, medical imaging, and data visualization applications. For more information, visit the `official VTK website <https://vtk.org/>`_.

VTK is a comprehensive library that provides algorithms and tools for visualizing scientific data, including support for various data formats, rendering techniques, and interactive visualization capabilities.

.. note:: On Discoverer HPC, the VTK library is used to support visualization capabilities for various scientific applications, including those compiled with LAMMPS.


Available versions
------------------

To view available VTK versions::

    $ module avail vtk

Build recipes and configuration details are maintained in our GitLab repository:

* `Build Recipes <https://gitlab.discoverer.bg/vkolev/recipes/-/tree/main/vtk>`_


Access to the VTK library
-------------------------

To access the latest version of the VTK library, load the module without specifying the version:

.. code:: bash

    $ module load vtk


In case you need to access a specific version of the VTK library, you can specify the version:

.. code:: bash 

    $ module load vtk/<version>


Compiler support
----------------

We use the recent :doc:`llvm` to build the VTK library code. We do not support any other compilers for that purpose. The `LLVM.org <https://llvm.org/>`_ compilers are the default compilers on Discoverer Petascale Supercomputer. Since the code of the library includes both C++ and Python components, the compiled binaries are compatible with various programming environments.
