Hello,
In the default Xcode 4.x OpenGL ES iOS template, why doesn't Apple use indices when drawing the two cubes? How does OpenGL know what order to draw the coordinates. Also, Apple uses normal values in with the vertex data -- how does OpenGL know what is a normal coordinate vs a vertex??
Thanks!
