Really, thank you Stephan, but it does return the right value: 3. Hmm, since it works with glDrawArrays, the glVertexAttribPointer should be allright, right ?

Thank you, but that is not it. And you dont need glGenVertexArraysOES, it is only for optimization copying between the Cpu and the Gpu if you change the state of the context.

comment The purpose of using invert and transpose
Thank you all for your replys. Just to be clear, you find the normal by invers from projection matrix to ModelView matrix and then the transpose of this(a tangent vectors) will give you the direction of the normal. Sorry, but I am just learning to wrap my head around this.
