Field of view of camera

[lindsayts]

In the log a parameter is printed "viewingFOV" can this be changed and how is it done. Its not in the registry.

A web search came up with the explanation that the parameter is OR's vertical field of view. The default value 45 makes the FOV to wide for wide screen monitor (I think anyway).

Any settings that are on their default values aren't saved in the registry; you can add them, though, to change it.

Thank you, I managed to work that out.

I set viewingFOV to 28, I use a 30 inch 2560x1600 monitor, 28 degree FOV equates to 45 degrees horizontally on my monitor (Note 1). I found the difference quite striking, the very first impression on getting in the cab (a DMU) was that looks way more natural. I found the viewing direction in the cabview file required fine tuning on some machines.

I found one could identify a semaphore signal against a contrasting background at a distance of nearly a kilometre. Judging the distance to stop at a platform was easier and you could see the vertical curves in the track much more like reality.

Disadvantages are one can see details better so low detail items standout more and its much easier to spot line side scenery items that do not have LOD's being drawn. Also the scenery looks somewhat sparser.

For me though the benefits (its closer to reality) far out way the disadvantages.

Note 1: A 45 degree vertcal FOV on my monitor equates to a 72 degree horizontal FOV. This is well into the area of wide angle lens, a standard lens on a camera say a 50mm on a 35 mm camera is usually around 39 degrees FOV.

The Portrait lens for a 35mm camera is an 85mm which gives a 29 degree FOV. This was used because it is thought to give the perspective closest to that which we see things. Obviously our peripheral vision means that we "see" a lot more than the bit our brain focuses on?

What would be really good would be to be able to alter the FOV on each individual view within OR? Much as you can with MSTS. For example I always have my 3 cam in MSTS a moderate wide angle and my 2 cam as an 85mm (29 degree FOV) cam. At the moment I'm having an issue with the up/down arrows in the cab FRONT view whereby I can only see the track in front of the train. (THIS IS IN v0.9 BTW) and although the up/down works initially after a few cm changes I get stuck looking down
