Since 2001, OGRE has grown to become one of the most popular open-source graphics rendering engines, and has been used in a large number of production projects, in such diverse areas as games, simulators, educational software, interactive art, scientific visualisation, and others. OGRE supports Windows (all major versions), Linux, OSX, Android, iOS, Javascript (via EMScripten), Windows Phone (Sponsored by Microsoft) and WinRT. Also, OGRE was ported to PS3 and Xbox360 for several titles. Ogre is released under the MIT License, which is a permissive open source license. The only condition is that you distribute the license text included in our distribution with any software that uses OGRE. Learn OGRE using our series of introducatary Tutorials. Of course the OGRE team provides official documentation in form of the OGRE Manual and API documentation.
