OpenGL Vertex Array - Song Ho

So what you might want to do is keep track of how many verts make up your model and then whenever you hand them over to OpenGL, you let it know what is going on. So, you need to buffer 6 verts instead of 3 and you need to draw 6 verts instead of 3. Edit 2. Also, I think you have mismatched wind orders.
