With recent 3.4.x onwards you also have the option of passing in constants via #prama(tic) shader composition system that passes #define values into the compilation of shaders. Shaders are a big topic so it's impossible for me to give you a full guide, there are plenty of reosurces online about GLSL shaders, within the OSG search for uses of osg::Program, osg::Shader, osg::Uniform.
