OSGUIsh is a library that generates GUI-like events from nodes in an OSG scene graph. So, a programmer can install callbacks that are executed when the mouse moves over a node, or when it is clicked, or double-clicked, or the mouse wheel moves, or... you got the idea. It still lacks an User's Guide, but I think the demos are simple enough to show its usage. Enjoy it, if you can, ;-) Leandro Motta Barros
