You are free to use SCaVis for academic research, in institutions of higher education, K12, non-profit organizations and for personal use (but not for your business). If you will use it for COMMERCIAL purposes, you should become a SCaVis member or contact us at scavis(AT)jwork.org (replace (AT) by @) to receive a version of this program with a more permissive license and redesigned libraries. Use the [Member login] link to unlock documentation for advanced usage of SCaVis as well as to obtain a permanent link to a version of this program with a license for commercial usage.
The core numerical and graphical libraries are licensed by the GNU General Public License v3 or later. However, documentation libraries, examples, installer, code assist database, language files integrated into the SCaVis IDE software package are not licensed by the GPL license and free only for NON-COMMERCIAL purposes (academic research, science and education).
Thus, the entire program cannot be used for a COMMERCIAL purpose. If you use it for COMMERCIAL purposes, you should become a member of this project to receive a redesigned version of this program (a professional edition, SCaVis-Pro) suitable for commercial purpose.
It should also be mentioned that a large portion of the online manual is not accessible for non-members (they will see many yellow boxes protecting the manual from guests). This may not be a problem for an elementary level, but at some point you may need to discover the full potential of this software. After becoming a member, a full access to this manual is granted automatically (plus many other benefits). See the member link.
