How it became four-dimensional? Did you mis-wrote it? The fourth dimension is "the time".

Just quote inspector spacetime, but your are right it's the wrong term. It's two dimensional.

It's only up/down, which with 2 engines gives 2 dimensions of control (pitch and roll). The engine's exhausts are actually circular, but they have added IR shields which double as the thrust vectoring surfaces.

I have seen a documentation of F-22 engine. Vector thrust skewing from left to right and up and down.

You just contradicted yourself. You said it's 2 dimensional, then said it has left-right and up-down vectoring, which would make it 3 dimensional. You don't have a clue what you're talking about.

2 dimensional: length and width / up and down as left and right in our case
3 dimensional: length, width and depth

As I said, my post was regarded to my quoting. Again, I used the wrong term 3 dimensional. You should better read @Hexciter 's reply.
 
The number of dimensions of a thrust vectoring system is determined by the number of degrees of freedom that can be controlled with the system.
So if there was one engine and it could turn up/down, it could only control the pitch of the aircraft. That is 1D.
If there was one engine and it could turn up/down and left/right, it could control the pitch and the yaw. That is 2D.
If there were two independent engines and both could turn up/down and left/right it could control the pitch, yaw and roll of the aircraft. That is 3D.
So in this case, yes the F-22 does have 3D thrust vectoring. Because it has two 2-D thrust vectoring engines (1st D = up/down, 2nd D = left/right) that can function independent of each other and thus make up a 3D system.

You boy, talking about different dimension.

Wrong again. Stop arguing about things you don't know anything about.
Why are you guys arguing about the semantics of it all? I was the one that said 4 dimensional, I may have used the wrong analogy here, but within the context of the discussion it's easy to understand what were are discussing about.

But both engine's of the F-22 seem to be only be able to go up/down though. The Russian SU-30MKM also only seems to be 2 directional, but each engine is canted at an angle:

According to the Wikipedia page: https://en.wikipedia.org/wiki/Sukhoi_Su-57#Engines, The T-50 will use engines with similar thrust vectoring to the Su-30MKM.
Quote from Wiki: "The two 117 engines incorporate thrust vectoring (TVC) nozzles whose rotational axes are each canted at an angle, similar to the nozzle arrangement of the Su-35S. This configuration allows the aircraft to produce thrust vectoring moments about all three rotational axes, pitch, yaw and roll."
Wonder if the F-22's configuration can produce thrust vectoring to all three rotational axes.
 
Pardon ... but since when is the TVC-version of the RD-33 "mass-produced" ?

It is related to the omnidirectional nozzles refferring to Klimov's website, Klimov is supplier for Russian aircraft engine industry. EJ-2000 can also upgraded with multidirectional nozzles, depends on who supplies them.
