The mechanism for distributing plugins written by the PIIP project has changed from May 2017. Compiled plugins will now be distributed with the Sedeen viewer. This is to ensure that the plugins can be recompiled everytime that upgrades are made to the Sedeen Viewer.
Source code is now available from a GitHub Repository: http://github.com/sedeen-piip-plugins/.
We are currently working on a mechanism for the wider community to develop algorithms using the Pathcore SDK and to controibute them to the repository.
