OGRE (Object-Oriented Graphics Rendering Engine)

Demo Distribution README file

http://www.ogre3d.org

Summary

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. 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.

To run these demos you need to have DirectX 9 installed, although you can also choose to run the demos in OpenGL if you wish. 

So now what?

These demos are only a small sample of what you can achieve with OGRE. For more eye candy, visit the Official Web Site, and click on 'Featured Projects. If you would like to start making applications using OGRE, you can download the latest source code and documentation from the site

Licensing

OGRE is available free (both 'free as in beer' and 'free as in speech') under the GNU Lesser General Public License or LGPL (see Docs/licenses/lgpl.txt). By downloading and using the software, you are subject to these licensing conditions, so please read the license text carefully. The LGPL is compatible with almost all possible uses of the library (including commercial uses), but there are some responsibilities placed upon the user to maintain the freedom of the software for downstream users.

Alternatively, you may license OGRE under the OGRE Unrestricted License (OUL) which comes with fewer conditions than the LGPL. This license is commercial and basically allows you to pay for the privilege of side-stepping the responsibilities of the LGPL. The software in both cases is identical, only the licensing conditions vary. If you wish to discuss this option  please mail licensing@ogre3d.org for more details.

Licensing for 3rd-party libraries used in OGRE

Several 3rd-party libraries are used in OGRE for various purposes, and the licensing details of each are given here.

Core Dependencies

These are the libraries which the core of OGRE depends on, and are therefore prerequisites for any use of OGRE. None of these libraries have been modified from their original distributions, and they are all licensed under liberal terms. You should read the detail of the licenses when distributing an application since most require you to include the license in your documentation. All the license texts are included in the Docs/licenses folder.
