Based off of what I can infer, the field-of-view is the same in any direction, up, down, left or right. The only difference is that we go further left and right that up and down with the camera aspect ratio. However, that shouldn't change anything since we know how much further left-right we go verses up-down.

However, if there is an actual difference (stating that I am incorrect with what I said above which I completely can be), then if we are using the width of the image, then we should be rating our distance based off of the horizontal length of rectangles, not the height of them.

Haha ya, more info as to what they are trying to accomplish here would help out a lot. Right now I'm not really wanting to change their example code but it does seem like something is either misplaced or at least not the whole story is being told.
