FOV in model view & distance to object

[mcstieg]

Hello Alexey!

Hope you're doing well!

Would you please explain how  the perspective "FOV" in the model view is calculated?
I'm trying to suggest the distance from a scanned object in a photograph...

For example:

• if you have a face scan...
• FOV 70: you can see the ears from the front
• FOV 30 to 0 : you can't see them

It's the same then stepping back and forth - changing the distance to the object. Hopefully you can help me out!

THANK YOU VERY MUCH!

Hi mcstieg,
I'm not that guy but I want to let you know (and everyone else) that you asked question that interest me most these days cause I want to make video animation which overlaps with cameras views. I'm very grateful to you because of that.

I have message for Alexey too, if he see this:
I posted similar question on this forum, here's the link:

I want to know how that FOV works, and I'm not only guy who is interested in that theme.
Thanks !
