First, make sure you have installed an SVN client on your system. If your system is a Debian-based GNU/Linux system (such as Ubuntu, Knoppix etc), you can install SVN by
sudo apt-get install subversionif you are using a Redhat-based GNU/Linux system (such as Fedora, CentOS etc), you can do this by
su -c 'yum install subversion'If your operating system is Windows, we recommend you installing TortoiseSVN.
The latest code snapshot can be checked out from project's SVN repository. It can be checked out anonymously by the following command.
svn checkout svn://svn.code.sf.net/p/iso2mesh/code/trunk/iso2mesh iso2mesh
After checking out the code, you need to set up the path based on the installation instructions. Then you can start matlab or octave, and run the example scripts under the sample directory.
If you are one of the developers who have SVN write-permission, you can checkout the latest code with the same command above.
Once checkout, you can simply make changes or debug your changes in your local copy. If your local changes have passed review by other co-developers, you can then commit your changes back to the SVN repository by
cd /path/to/iso2mesh/local/copy svn commit -m "a short summary of your changes"
GNU Public License (GPL). However, it included a number of external tools (under bin/ directory) to perform certain functionality by means of pipelines. These external tools are subjected to their upstream licenses and are not necessarily GPL (or GPL compatible). The complete list of these external commands and their author info and licenses can be found from the README page.
Particularly, the 3D meshing tool, tetgen, is licensed under a non-free license: it can be freely used, modified, redistributed only for research and academic purposes, any commercial utility of tetgen requires a permission from its original author. iso2mesh calls tetgen in the background to produce 3D mesh, that means if anyone needs to uses the 3D mesh produced by iso2mesh in a commercial product, you MUST contact the author of tetgen to get permission. Processing binary images and produce surfaces are not subject to this limitation.
In additional to the licenses, if you use this tool in your research, we are greatly appreciated if you can add iso2mesh to your references:

If you used cgalsurf or cgalmesh options in your mesh preparation, you should also acknowledge CGAL publications. If you generated your mesh with the tetgen module in iso2mesh instead of CGAL mesher, you may need to acknowledge tetgen in your publications, you can find more references from this link.
