OpenSceneGraph 2.4

OpenSceneGraph (OSG) is a set of tools to develop and manipulate images in 3D.
This image toolkit allows creating 3D images for different purposes as virtual reality, games, modeling and any other application that need to use volume images.
Its installation process is very easy to perform and the link provided to download the installation file was built for Microsoft Visual Studio V8.0 (2005) SP1 on Windows XP SP2; however it contains the source code if you need to rebuild it for other IDE, or if the binaries don't work as expected. To perform this rebuild it will be necessary to download the CMake program and follow the instructions included in the OSG program.
OSG can be added to the Microsoft Visual Studio projects and it can be used on any project that needs 3D images manipulation.
Moreover, it provides a couple of viewers to show the osg files: osgviewerGLUT and osgviewerMFC.
It doesn't offer a GUI, but its shapes and volumes in 3D can be customized to provide textures or images with great quality. Its included documentation is very basic; however on its website there is more information and even some manuals and books that can be purchased.
OpenSceneGraph runs any platform although it is Open Source code.
