+// ***** OculusWorldDemo Description
+
+// This app renders a simple flat-shaded room allowing the user to move along the
+// floor and look around with an HMD, mouse and keyboard. The following keys work:
+//
+// 'W', 'S', 'A', 'D' and Arrow Keys - Move forward, back; strafe left/right.
+// F1 - No stereo, no distortion.
+// F2 - Stereo, no distortion.
+// F3 - Stereo and distortion.
+// F4 - Toggle MSAA.
+// F9 - Cycle through fullscreen and windowed modes. Necessary for previewing content with Rift.
+//
+// Important Oculus-specific logic can be found at following locations:
+//
+// OculusWorldDemoApp::OnStartup - This function will initialize OVR::DeviceManager and HMD,
+// creating SensorDevice and attaching it to SensorFusion.
+// This needs to be done before obtaining sensor data.
+//
+// OculusWorldDemoApp::OnIdle - Here we poll SensorFusion for orientation, apply it
+// to the scene and handle movement.
+// Stereo rendering is also done here, by delegating to
+// to Render function for each eye.
+//
+
+//-------------------------------------------------------------------------------------
+// ***** OculusWorldDemo Application class
+
+// An instance of this class is created on application startup (main/WinMain).
+// It then works as follows:
+// - Graphics and HMD setup is done OculusWorldDemoApp::OnStartup(). This function
+// also creates the room model from Slab declarations.
+// - Per-frame processing is done in OnIdle(). This function processes
+// sensor and movement input and then renders the frame.
+// - Additional input processing is done in OnMouse, OnKey.
