Trying to work out the Cesium.PerspectiveFrustum(options)

I think I need to use the following

fov
Number
optionalThe angle of the field of view (FOV), in radians.
Here are my camera specs.
V.FOV deg
H.FOV deg
Diag. FOV deg
16 x 9 M
55
94.4
107.1
Medium FOV
21.9mm

How can I set this to the viewer FOV?

Hey Chris,

I’m not super familiar with how camera specs are specified, but here’s my best guess–

Medium FOV
21.9mm

Here they’re specifying the focal length of the camera lens, and you can use that to calculate the actual FOV angle. Make sure you provide it in radians as the documentation specifies.

Hope that helps!
