Finally we start to get to nearer to what you are actually after. It really shouldn't take others in the community to drag out of what you actually need. You should put the effort into your original posts that properly describe the problem you are trying to solve. For projecting a grid onto terrain the best route is to use multi-texturing and leverage the fact that OpenGL supports wrapping of texture coordinates so that a single texture can reapeat forever. Create a texture with the grid on and then apply this to your geometries either directly or applying it over the whole scene and using texture generation on the GPU to covert the local coordinates into the correct coordinates in the texture. Personally I'd opt for the later approach. You need to learn about projective texturing, there are plenty of resources on the web, just go to google and start searching. Also look through the OSG code bases for places where osg::TexGen/TexGenNode are used as these will provide another resource for learning about the topic. Once you haven't done the background learning the route forward should become much clearer.
