Open Scene Graph

The Open Scene Graph (OSG) is an Open Source (LGPL), Stanadard C++, OpenGL based scene graph for cross-platform 3D real-time visualisation..  The OSG is simply a scene graph and by design does not attempt to encompass application frame works and user interface, the design is kept focused on the issues of representing a 3D scene and rendering it in real-time.

There are also support libraries such as osgGLUT for bringing up a basic UI, however this is not the focus of the OSG.  For more sophisticated user interfaces it is recommended to intergrate the OSG graphics with a fully fledge UI toolkit, this has already been done by users for FLTK, WxWindows and X, with the potential for many more.

This release is a ALPHA version, and is subject to continuous development with the API of features subject to change.

For instructions of how to compile, install the osg libraries and to run the demos please read the README file.

Regards,

Robert Osfield.
