OGRE (Object-Oriented Graphics Rendering Engine)

SDK 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.

This distribution contains the precompiled SDK release of OGRE and is the most convenient way of obtaining the engine. The full source code is also available, for people who want a little more flexibility or who are just curious as to the inner workings of the engine; go to the main OGRE web page for full details.

Index Of Contents

What's New?

A summary of the new and altered features in this release.

The OGRE Wiki

A gold mine of tutorials, tips and code snippets which will help you get up to speed with the engine. This is probably the best place to start learning OGRE.

The OGRE Manual

A descriptive reference to the major parts of the engine such as scripts.

API Reference

The full OGRE API documentation, as generated from the (heavily!) commented source.

Keeping Up To Date

The best place to keep up to date with developments on OGRE is the Official Web Site. From there you can download the latest source code and documentation. You can choose between keeping bang up to date with CVS (Concurrent Versioning System) or by just getting the regularly released snapshots.

The changes included in this current version can be viewed on the ChangeLog.

Getting Support

Please use our extensive forums if you need help or think you may have found a bug. Go to the main web site and click on the Forums link.

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.
