Angular distance between 2 object with unity

Hi,

I'm new in unity software development with FOVE and i will use it in an unusual way:

the goal is to display 2 objects in a 2D environment ,show them in only one eye and get the angular distance between them.

I overridden cameras and so i can switch off one of them and see objects with one eye and not with the other, now i need to calculate the angular distance and here start my problems.

What is the size of display in pixel? what is the max visual angle?

Thanks

Stefano

  The display is a 3440*1440 OLED and it's 5.6"

  Calculating the maximum visual angle is tricky (not all users are the same distance from the screen, with a 2D representation the objects are approximately 3m(perceived) from the user which is how we've set the default.

  Hi Jeremy,

  A couple of queries:

  1. Could you clarify on what the value 5.6" refers to?

  2. How did you arrive at the value of 3m?

  3. What is the distance from the screen to the lenses (not the users eyes)? A rough figure would suffice I guess.  

  Kindly, let me know. Thanks!

  Hi Jeremy,

  What if i set a camera that is 1 unit far from 2D objects and a world scale = 1? it's mean that object are approximately at 1m (perceived)?

  Thanks

  It's very, very approximate, but in theory yes.
