Oooh. I thought the distance was a radius thing. 'You have the pan the camera this much in some direction' kind of thing.

 

However, it looks like distance calculate is coming up short.

 

Before panning:

After panning:

[attachment=13887:after pan.png]

 

Now ignoring that the panning is wrong, the box should fit the screen, or at worse, spill past either the top or bottom of the screen due to bad/no panning. The distance calculation seems fine.

 

 

bottom size = half map x * absolute(x-axis • bottom normal) +
                      half map y * absolute(y-axis • bottom normal) +
                      half map z * absolute(z-axis • bottom normal)
left size = half map x * absolute(x-axis • left normal) +
                half map y * absolute(y-axis • left normal) +
                half map z * absolute(z-axis • left normal)
and etc..
 
vertical distance = (top size + bottom size) / (2 * sin(vertical FoV / 2))
horizontal distance = (leftSize + rightSize) / (2 * sin(horizontal FoV / 2))
 
distance = max(vertical distance, horizontal distance)
 
camera position = normalized camera direction * distance
