Suggestion: make the standard FOV 40 degrees

Something I've been wondering is: why does SpaceEngine have 60 degrees as its standard Field of View? This is a very large FOV, and produces pretty huge, ugly deformation near the edges of the screen. It also means things look far smaller than they would in reality. Compare how the Moon looks from Earth at 60 degrees:


And at 20 degrees, which is a realistic FOV for most monitors:



It should be quite clear which of these is a realistic look of the Moon. Now, I understand that 20 degrees is quite a cumbersomely small FOV, which can make it hard to find things at times. That's why I think SE's standard FOV should be 40 degrees. This FOV produces distortion, but it's not nearly as pronounced and ugly as in 60 degrees. And it's much easier to find things with than 20 degrees.

Now, I know you can just edit Main.cfg to change the standard FOV, and actually did so in my install to make it 20 degrees. But I think if 40 was made the standard in SE's next version, the average quality of many people's screenshots and videos, which tend to be made at the standard FOV, would improve a lot.

I like the 60 degrees FOV , but I agree that making the default FOV at 40 could give a much more cinematic and captivating immersion.

I agree. And I think that the quality of people's experiences might be improved as well. Personally I prefer 45°, but anything larger than that just causes too much distortion.

20° might be appropriate for some if they use a very small monitor, but if you have a large, high resolution display then 20 is far too small to be the default. Celestia had a clever way of dealing with this problem; FOV was per pixel rather than absolute, so the default FOV settings would show everything at the same angular resolution regardless of screen size. It worked quite well.

^My own monitor is quite big, and simply by using the rule of thumb that a stretched hand at arm's length is roughly 20 degrees, I can determine it's about 25 degrees from top to bottom of the screen from where I sit. So I don't think many people have monitors larger than 30 degrees, unless they sit with their noses right on the screen.

Well, there are quite a few complications with that line of thinking, not the least of which is that not all displays have the same pixel size. And then there is the fact, as you mentioned, that not everyone sits at the same distance from their monitor. So trying to come up with a default FOV that allows everyone to see things at the same apparent size as they would with their eyes is a doomed effort.

Plus, as you also mentioned earlier, a small FOV makes it cumbersome to navigate and seek objects. But I think you're right about 40° as a default, it strikes a good balance between realism and ease of use.

My monitor is around 2 Ft (~0.6 m) from my face on average and I find in most games I enjoy an FOV of 90. In Space Engine the default of 60 seems to work fine and for screenshots I use something like an FOV of 5.

Agreed here, the default FOV looks completely natural for me, and 60 FOV is a lot closer to natural human FOV then 20 or 40.

Using 20 or 40 FOV with a 1980x1080 screen it looks like I'm trying to peer out of a tiny window. With the default it's like I'm actually floating there with peripheral vision possible. And I can't notice any distortion at all near the edges, unless you do something crazy like 90 FOV. cool

Like the tiny windows on your ship? pocus

I find that hard to believe, just look at a planet, then move it to the edge of the screen at FOV 60... it is very obviously distorted, it is no longer circular.

Below is a comparison of the planet centered (a perfect circle) then at the edge at FOV 40 and FOV 60. If you still insist that you see no difference between the two, then I advise you to visit an optician.

Interesting comparison Harbinger. I'm going to try out using 40 fov and see how well it works I rather like the lack of distortion.

I propose a compromise variant: 45° smile

I wiki'd it, and it says that the human FOV is nearly 180". blink

That is because we have very wide peripheral vision. Compressing that onto a screen would look -very- odd.

Too bad they're insanely expensive.

That wouldn't exactly cut it. What you really need is a planetarium-like dome with projectors (this has been discussed in another thread). That way, things that are projected at the edge of a large FOV will be at the edge of your real FOV, and also projected onto a spherical-shaped screen. That way everything looks natural. The ultimate simulator experience cool
