Detailed Description

osg::Program is an application-level abstraction of an OpenGL glProgram.

It is an osg::StateAttribute that, when applied, will activate a glProgram for subsequent rendering. osg::Shaders containing the actual shader source code are attached to a Program, which will then manage the compilation, linking, and activation of the GLSL program. osg::Program will automatically manage per-context instancing of the OpenGL glPrograms, if that is necessary for a particular display configuration.
