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 applications utilising hardware-accelerated 3D graphics. The class library abstracts all the details of using the underlying system libraries like Direct3D and OpenGL and provides an interface based on world objects and other intuitive classes.

OGRE v1.0 [Azathoth] represents the culmination of 4 years of continuous development, resulting in what is now regarded by many as the leading open source real time 3D rendering engine. OGRE is packed with features to make your development life easier, whether you're making games, architectural visualisation, simulations, or anything else which requires a top-notch 3D rendering solution.
