Vivek's email to osg-submissions: "I'm happy to release the osgdragger nodekit to the OSG community. I implemented the nodekit for my company, Fugro-Jason Inc., and they have kindly agreed to open source it. The nodekit contains a few draggers but it should be easy to build new draggers on top of it. The design of the nodekit is based on a SIGGRAPH 2002 course - "Design and Implementation of Direct Manipulation in 3D". You can find the course notes at http://www.pauliface.com/Sigg02/index.html. Reading pages 20 - 29 of the course notes should give you a fair understanding of how the nodekit works. The source code also contains an example of how to use the draggers."
