Voreen is an open source volume rendering engine which allows interactive visualization of volumetric data sets with high flexibility when integrating new visualization techniques. It is implemented as a multi-platform (Windows and Linux) C++ library using OpenGL and GLSL for GPU-based rendering, licensed under the terms of the GNU General Public License.
The Voreen project has been initiated in 2005 at the University of Münster as subproject of the collaborative research center SFB 656, and is now developed cooperatively between the University of Münster and Linköping University.
