   easy normal mapping?
  As someone who lacks experience and knowledge of advanced graphics techniques, is there relatively simple way in which I could implement some form of normal mapping into my 2d isometric opengl based game without using shaders and the like?   
  Before shaders came around, normal mapping was usually called "Dot3 bump mapping" - you might be able to find some info under that name.There should be a (fairly easy) way to do Dot3 using OpenGL fixed function graphics.   ;Quote:Original post by ari556655As someone who lacks experience and knowledge of advanced graphics techniques, is there relatively simple way in which I could implement some form of normal mapping into my 2d isometric opengl based game without using shaders and the like?It might worth the effort to implement it using shaders anyway, as it is not all that hard: I did it a couple of years ago, and I never used OGL or DX extensively, and it was my second shader in my life, just after shadow mapping...then of course I don't know what other texturing and lighting are you using, and switching to shaders just for that might not be the best thing to do...
