View Full Version : Viewport Grid of 1 degree

06-23-2014, 12:46 PM
I created a Viewport Grid of 1 degree resolution. This is useful to estimate difference in bearing and elevation to a point (for example to estimate the required aperture of an antenna).

It assumes that horizontal FOV in GE is always 60 degrees.
The grid includes the viewport distortion (hopefully accurate enough. FYI I did this effect in Gimp using Lens distortion with a value of -36)
