almost, but you need to bump the pointer instead of using cubeVertices for all 3;
Well in my case I was using all GL_FLOAT, I think mixing float, byte & short complicates the offset. Maybe the offset is in bytes and you need 7*sizeof(). Truth is I have not done it yet. I have just been reading up on it. I am using non-interleaved data for now. I think with the FloatBuffer class you can do the pointer manipulation to get the offset pointer.
