Virtual Reality Simple Field of View Restricter

Description:

This is a simulated simple field of view restricter which will help minimize motion sickness from a virtual reality glasses. I read an article at http://spectrum.ieee.org/tech-talk/consumer-electronics/gaming/dynamic-field-of-view-restriction-makes-virtual-reality-less-barfy. Ensure you move you viewport away from the objects because when you run the app, (press P), the right and left eye will usually display the back objects if you set it to a blank area. I updated it to include a text value as well as having only the right eye and main camera active in the viewport.
