2. License issue

2.1. What kind of licenses exist for ViSP?

The ViSP software is released under a dual licensing model: the GNU GPL version 2 for developing open source software under the terms of the GPL license, and the ViSP Professional Edition License for the development of proprietary software.

Don’t hesitate to contact visp@inria.fr if you have questions about our licensing model.

2.2. What are the differences between the GNU GPL license and the Professional Edition license of ViSP?

The GNU GPL version 2 license is appropriate for the development of applications where you wish to use ViSP in combination with software subject to the terms of the GNU General Public License version 2 or where you are otherwise willing to comply with the terms of the GNU General Public License version 2.

The ViSP Professional Edition License is the appropriate version to use for the development of proprietary software. This version is for developers who do not want to share the source code with others, or otherwise do not comply with the terms of the GNU GPL version 2.0. In other terms, with the Professional Edition License you avoid the licensing restrictions of the GPL. If you are interested by this license, contact visp@inria.fr.

2.3. I don’t want to give away my source code. What do I do?

Then you need the ViSP Professional Edition License. Please contact visp@irisa.fr.
