+// ***** OculusRoomTiny Description
+
+// This app renders a simple flat-shaded room allowing the user to move along the
+// floor and look around with an HMD, mouse, keyboard and gamepad.
+// By default, the application will start full-screen on Oculus Rift.
+//
+// The following keys work:
+//
+// 'W', 'S', 'A', 'D' - Move forward, back; strafe left/right.
+// F1 - No stereo, no distortion.
+// F2 - Stereo, no distortion.
+// F3 - Stereo and distortion.
+//
+
+// The world RHS coordinate system is defines as follows (as seen in perspective view):
+// Y - Up
+// Z - Back
+// X - Right
+const Vector3f UpVector(0.0f, 1.0f, 0.0f);
+const Vector3f ForwardVector(0.0f, 0.0f, -1.0f);
+const Vector3f RightVector(1.0f, 0.0f, 0.0f);
+
+// We start out looking in the positive Z (180 degree rotation).
+const float YawInitial = 3.141592f;

+// ***** OculusRoomTiny Application class
+
+// An instance of this class is created on application startup (main/WinMain).
+//
+// It then works as follows:
+//
+// OnStartup - Window, graphics and HMD setup is done here.
+// This function will initialize OVR::DeviceManager and HMD,
+// creating SensorDevice and attaching it to SensorFusion.
+// This needs to be done before obtaining sensor data.
+//
+// OnIdle - Does per-frame processing, processing SensorFusion and
+// movement input and rendering the frame.
