As far as I can tell GL_NORMALIZE will only normalise vertex normals. Just to clarify its the vertex position I wish to normalise and then scale by w to achieve what I can only describe as a fish-eye effect in rendering the geometry.
This is trivial with a vertex program, the reason I'm keen to avoid doing so is to have my engine work on low-end systems i.e. laptops. as I'm intending to develop a 'casual' game. Maybe I am underestimating my potential user-bases sytems?
