%description

The Open Scene Graph is a cross-platform C++/OpenGL library for the real-time 
visualization. Uses range from visual simulation, scientific modeling, virtual 
reality through to games.  Open Scene Graph employs good practices in software
engineering through the use of standard C++, STL and generic programming, and
design patterns.  Open Scene Graph strives for high performance and quality in
graphics rendering, protability, and extensibility
