Re: New Terrell Rotation Animation

I've seen Terrell rotation "explained" this way: "seeing" the relativistic object as if rotated, while the combination of length contraction (a Lorentz feature) and Terrell rotation (a Doppler feature) leaves the object "seen really uncontracted" (!!!). An excellent example of dialectic confusion between two kinds of SRT "observation":
Lorentz features (measurement, back-calculation results), and
Doppler/"Einstein" features (actually *looking* at relativistic motion).

I have been explaining for years how to do it to many people, but the problem is that my clarifications are so powerful and irrefutable that it makes people laugh.
It is an incredible phenomenon in the history of humanity, but it is very real.
A man speaks, he explains the whole RR clearly, he says how to do it, and everyone howls with laughter.
This behavior, finally, is logical.
Let's imagine a man who is looking for a translator capable of translating from Slovak to Vietnamese, and who lives in the Denver area. He searches for ten years, and he does not find one. Then suddenly, he is told that there is a nine-year-old boy, whose father was Slovak and whose mother is a Vietnamese refugee, who speaks and writes both languages ​​perfectly.
Everyone laughs. Everyone starts laughing.
I have the impression that it is a bit like that in physical science, as soon as we talk about the theory of relativity.
Your diagrams are not good, no one is able to represent what is happening.
This is much simpler than your representations which turn into the absurd. It is clear that two observers momentarily joint receive at this moment all the same photons from the universe and not "from others".
They therefore see exactly the same universe present, but very spatially deformed at the x level.
x'=(x+Vo.To)/sqrt(1-Vo²/c²)
y'=y
z'=z
t'=t (since they perceive the photons at the same place and at the same time for them).
There is therefore no deformation in y and z. No twisting or I-don't-know-what.
I'm willing to help a potential programmer do stuff, but if he doesn't listen to me, in a hundred years we'll still be making crappy videos.
