OGRE
scene-oriented, flexible 3D engine (C++, Python, C#, Java)
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 utilizing 3D hardware. 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. We consider the results of our GL3Plus RenderSystem as the gold standard. The respective shaders are generated by the RTSS component with per-pixel specular lighting. Therefore the legacy render systems naturally have differences due to the use of fixed-function. However, when rendering diffuse surface both produce pixel-perfect results. Simple, easy to use OO interface designed to minimise the effort required to render 3D scenes, and to be independent of 3D implementation i.e. Direct3D/OpenGL. -
