If you are looking for an introduction to modern OpenGL, with shaders and such, then [http://www.opengl-tutorial.org/ opengl-tutorial.org] is a good place to look.

If you are more specifically interested in normal mapping, then a really neat GLSL snippet can be found [http://www.geeks3d.com/20130122/normal-mapping-without-precomputed-tangent-space-vectors/ HERE] (an implementation of normal mapping that uses no precomputed TBN matrices and does all the tangent space math at shader level). | If you are more specifically interested in normal mapping, then a really neat GLSL snippet can be found [http://www.geeks3d.com/20130122/normal-mapping-without-precomputed-tangent-space-vectors/ HERE] (an implementation of normal mapping that uses no precomputed TBN matrices and does all the tangent space math at shader level). | ||
