I'm using OpenGL ES for the iPhone and am having a problem with using glLineWidth. When I render a line with glLineWidth set to something like 5.0 using the iPhone simulator ( an emulator that runs on a Mac ) everything works fine. However, when I try the same code on an actual device the lines always render with a width of 1 pixel.
Is there something special I need to do to get this working on an actual device? Any help would be great! Thanks!
