Voreen

Voreen is a powerful software tool that uses GPU-based state-of-the-art volume rendering techniques. It allows high frame rates on off-the-shelf graphics hardware, making it perfect for supporting interactive volume exploration. The tool's primary goal is to develop a volume rendering engine that allows interactive visualization of volumetric data sets while providing the flexibility to integrate new visualization techniques.

One of the significant benefits of Voreen is that its source code is available under the terms of the GNU General Public License. This makes it an excellent open-source option for users who need a reliable and flexible volume rendering tool.

Voreen emerged from the project Z1, which aimed to develop an interactive 3D-visualization of medical imaging data for the non-invasive analysis of cardiovascular processes and structures. The project was part of the collaborative research center SFB 656 MoBil Molecular Cardiovascular Imaging. It has been initiated and is maintained by the Visualization and Computer Graphics Research Group (VisCG) at the Department of Computer Science at the University of Münster.

Overall, Voreen is a comprehensive software tool that provides users with a broad range of features and options for volume exploration and visualization. Its use of advanced rendering techniques and flexible design make it a powerful option for users in various fields of study.
