### GLAirplay ###

===================================================================================================

DESCRIPTION:

Demonstrates how to provide a richer experience to your users when they are using Airplay by 

displaying your UI on the iPhone/iPad and your app/game contents on the second display. 

When AirPlay Mirroring is enabled, by default the same image appears on the screen of the host 

device and the external display. This sample demonstrates how to use the second display 

independently by showing separate content on each display. The sample includes a simple OpenGL ES 

view which renders a rotating cube and lets you change the cube's rotating radius using a slider. 

When there is no second display, both the slider and the OpenGL ES object are displayed on the iOS 

device's display; when a second display is activated, only the UI appears on the host device's 

display while the external display is used to show the OpenGL ES content. The sample uses OpenAL 

for 3D sound playback.
