Matching the field of view between Desktop and Oculus Rift DK2

[Qiliang He]

Hi,

I'm doing experiment comparing people's performance in Desktop and Immersive VR (Oculus Rift DK2). I need to match up the field of view in these two systems. I know the default FOV in Vizard in 40 degree vertically. Does it mean that the same applies to the Oculus headset? If not, do I need to manually change the field of view in Oculus?

By the way, is there a function to get the current field of view of the window?

Thanks a lot!
