NxOgre is a physics wrapper for PhysX¹.

It is open-source and released under the LGPL licence. It was created and maintained by Betajaen. There are two main versions of NxOgre; Bloody Mess and Bleeding. Bloody Mess is the latest unstable code and Bleeding is the older stable branch.

Although NxOgre has OGRE as part of it’s name, it will work with any renderer in 3D, 2D or even none at all. It comes with a single demo application framework called Cake in various forms, and a multi-purpose command-line/GUI application called Flour.
