Documentation

osgGL2::ShaderObject is an application-level abstraction of the OpenGL Shading Language glShaderObject. It is a container to load the shader source code text and manage its compilation. A ShaderObject may be attached to more than one osgGL2::ProgramObject. ShaderObject will automatically manage per-context instancing of the internal objects, if that is necessary for a particular display configuration.
