About Voreen

Voreenve-2.pngVoreen is an open source rapid application development framework for the interactive visualization and analysis of multi-modal volumetric data sets. It provides GPU-based volume rendering and data analysis techniques and offers high flexibility when developing new analysis workflows in collaboration with domain experts. The Voreen framework consists of a multi-platform C++ library, which can be easily integrated into existing applications, and a Qt-based stand-alone application. It is licensed under the terms of the GNU General Public License.

The Voreen project has been initiated and was originally maintained by the Visualization & Computer Graphics Research Group at the University of Münster as part of the collaborative research center SFB 656 MoBil (Project Z1, Project Ö).

Since 2018, Voreen is collaboratively developed by the Pattern Recognition and Image Analysis (PRIA) Research Group and the VISualization & graphIX (VISIX) Research Group.

If you use Voreen in your research, please cite it in your publications.

Documentation updated - 11/28/2018

Information about Voreen's Python Scripting functionality has been added to the Documentation section.

Updated downloads - 09/18/2018

The source code download archives of Voreen 5.0.1 were missing geometry example files for some of the template workspaces. The downloads have been updated and now include the missing files. Moreover, we updated the pre-built HDF5 library for Windows to fix problems with Visual Studio 2017.

Voreen 5.0.1 is available - 09/06/2018

Voreen 5.0.1 is now available and fixes several minor bugs that occured in the previous release. Moreover, Voreen now includes a workspace specifically tailored towards ultramicroscopy users. You can find an overview of the changes in the changelog

You can find the current release in the download section

We will soon add additional documentation to the website, in particular for Voreen's Python scripting module.
