This sample introduces you to the use of Vertex Array Objects. They will allow you to record your Vertex States only once and then restore them by calling the glBindVertexArray function. As with the E* samples, look for the OSTEP tags to see how they are created and used.
To see a simpler version of this code that utilize utility classes from the DemoFramework take a look at the D1_2_VAOs example.
