OGRE (Object-Oriented Graphics Rendering Engine) is a scene-oriented, flexible 3D engine written in C++ designed to make it easier and more intuitive for developers to produce games and demos utilising 3D hardware.

This package provides the samples/demos so you can take OGRE for a spin.
Furthermore, the Ogre Mesh Tools (MeshUpgrader, AssimpConverter, XMLConverter) are included.
