Robert, I’ve written the shaders already and am well-versed in writing them. I just need a debugging tool that will allow me to see their values at runtime.

I can’t figure out this problem that we are having unless I can see the values in the shaders. To pass data into shaders you have use a combination of uniforms (osg::Unfiorm), textures (osg::Textre*) and vertex attributes. 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. Robert.
