Oh great.
I hate YouTube.
Anyway:
From what I know you'll need more than just a distortion of the field of
view; most notably, objects will appear "rotated" somehow.
There used to be a patched version of POV-Ray specifically designed to
simulate relativistic effects. It'll be quite out of date, but maybe
it'll do what you need.

I was going to see if I could find something else similar enough but instead
this other web page about physics rendered with P-R caught my attention.
Includes relativistic effects and links to more.
http://bugman123.com/Physics/index.html
The YouTube animation basically shows a series of accelerations showing a
stretching forward viewpoint and curving surroundings together with shifting
color (Redshift), also lack of color nearby.

Searched and found this web page of text+pictures about that. Was based on
POV-Ray 2.0, no luck locating the actual program. All broken links, as well as
the one from povray.org

I remember a video made with a patched version of povray from years ago.
I have never been able to find it again.
But using the wayback machine you can download the source code here
https://web.archive.org/web/19970220101552/http://www.cs.mu.oz.au/~andrbh/raytrace/raytrace_source.html
I hope it is the right one.

This was the thread I found it in.

Just 722 kByte in 46 source code files? With makefiles and all?
Wow -- if only modern POV-Ray was that lean ;)
Then again, that was over 20 years ago...

VSauce did an episode on this, so it probably contains information which is
probably current / accurate.

Hope that may help.
As others have pointed out, there have been a few attempts to do this in
POV-Ray. Very nice job digging that all up - source and everything! :)

I am sure you could do better. ÜbertreibenPov?

Ooooh yeah, source code for it in link there... now if I can recall how to
compile those things! thinking... nope. Going to need a refresher course, and a
compiler again!
Thanks very much Stephen!

It will cost you an animation. :)

Hey, watch that. I remember using POV-Ray 1.somethingoranother. Can't remember
which version exactly. But I have not used POV-Ray in 15 or 20 years or more.
