Why OSG?
The OSG project is open sourced and released under a modified GNU Lesser General Public License (LGPL), named OSGPL. It brings about significant benefits to its users:
- Rigorous structure: OSG makes full use of the Standard Template Library (STL) and multiple design patterns. It also takes advantage of the open source development model in order to provide a legacy-free and user-centric application programming interface.
- Superior performance: A series of scene graph techniques are already well-implemented in OSG, including view-frustum and occlusion culling, level of detail (LOD) configuration, rendering state sorting, particle and shadow supports, and complete encapsulation of OpenGL extensions and the shader language.
- High scalability:
