Computational Geometry Applets.
This is an old project I've started in 2008 which I decided to make available and make it easier to build (using Maven). More info about the project can be found in my personal page: http://www.kuniga.me/projects/geometry/
You can compile all the applets running the following Maven comand (at the root of the project):
mvn clean package
One way to try the applets is using appletviewer application:
appletviewer target/classes/index.php
