OGRE（Object-Oriented Graphics Rendering Engine，即：面向对象图形渲染引擎）是一个用C++开发的面向场景、非常灵活的3D引擎，它旨在让开发人员更容易、更直接地利用硬件加速的3D图形系统开发应用。这个类库隐藏了底层系统库（如：Direct3D和OpenGL）的所有细节，提供了一个基于世界对象和其他直观类的接口.详细的讲述了关于的各种类库-OGRE (Object-Oriented Graphics Rendering Engine, namely: object-oriented graphics rendering engine) is a development in C++ scene-oriented, flexible 3D engine, it is designed to allow developers to more easily and directly use the hardware accelerated 3D graphics system development and application. This library hides the underlying system libraries (such as: Direct3D and OpenGL) all the details, providing a visual based on world objects and other types of interfaces.
