I am creating a terrain engine for a game my friend and I are making, and I am having trouble with lighting. When I set up some GL-lighting, the terrain dosn''t get shade at all, it is just one solid colour. I not sure what it is that I have to do do acheive proper shading, I think I have to calcualte the vertex normals, but am not sure what they are, or how do calculate them. Could someone please explain what I must do, point me in the right direction, or give me some good tutorials dealing with this matter? Thanks
