OpenWalnut is an open source tool for multi-modal medical and brain data visualization. Its universality allows it to be easily extended and used in a large variety of application cases. It is both, a tool for the scientific user and a powerful framework for the visualization researcher. OpenWalnut is licensed under the terms of the GNU Lesser General Public License. Written entirely in Standard C++ and using a number of portable libraries (e.g. OpenSceneGraph and Qt) it runs on all Windows platforms, OSX and GNU/Linux operating systems.
