Fov vs focal length 2004-06-11 - By Arvid Björn
Back
Hey, I'm converting a list of shots with optics and distances to fovs
and 3D coordinates to match camera angles.
So I found the script belov in the archives. This was shot on Super16
tho, so what do I need to do to make this script accurate?
I read somewhere that the Super16 film height is 6.86mm, is that it?
I'm also a little confused as to use vertical or horizontal FOV for the
camera in XSI..?
I'd appreciate if anyone could confirm or correct any of this info!
Thanks,

Option Explicit
Dim VertAngle, Height, FocalLength, Pi, XSI_FOV
Pi = 3.1415926535897932384626433832795
Height = 24
FocalLength = 50
VertAngle = 2 * Atn (Height/(2 * FocalLength))
XSI_FOV = Round(VertAngle * 180/Pi)
LogMessage XSI_FOV
