Hi, Christian Use of glsl in osg is pretty straitforward. You create osg::Program (wrapper around gl program), osg::Shader(s) (wrapper around gl shader), set shader source with one of interface functions (or load from file), add them to program and set this stuff to stateset. If you use custom vertex attributes in your shaders - you should call addBindAttribLocation(..) of osg program with correct parameters. Uniforms passed to program through stateset with addUniform(). This is almost all you need to know about using glsl in osg. If you need to learn glsl itself you should look for glsl books, this stuff not related to osg in any way.
