The previous example programmed some pretty critical fundamentals of grabbing multiple Facebook images and pasting them into a 3D environment. We have yet to exploit the capabilities of interactive 3D worlds. Now, we shall add the ability to walk through our 3D Facebook world using the arrow keys and the mouse to navigate through Facebook pages. From here, we will use our imagination to create what a 3D social media world can become.
We continue to retrieve images using the facebook3dUI() function as in the previous example, but now we also call a new facebookFriendsNames() function that returns our friends' name and a link to their Facebook page and saves them in the facebookName and facebookLink arrays.
