Hi Luis and Wojtek
 
I send an image to make a test.
The square of the stereo pairs, abowe and below, have the perfectly same dimension.
 
If you look in cross the abowe square will appear more big of the below square.
Changing the stereo window you change the angle of the eyes vision.
 
If you draw two line departing from the eyes you easily find the rule that governs the change (mofification) of the perspective.
See the second atached image (eye.jpg)
 
That you write is a copy of many other writing but you have not a dimostration.
I give you a dimostration but I hope you undestang my bad english.
 
Ciao my math friends

Wojtek,
I agree with your definition of Window violation.
However it's possible to have some parts of the picture in front of the window
as long as they are not cut by a side of the window.
this property is used in public 3D shows, i mean 3D polarized movies in Disneyland France, futuroscope Poitiers, asterix park France. aso...
this effect is named "Jaillissement" in good French.( my dictionnary translates by "gushing", in English.) ,especially in 3D polarized movies it's very spectacular.
I donnow wether its a reversed perspective or not, sorry Gug, but the violation is due to the fact that a "gushing" object is cut by the side of the picture
when it's not cut the effect is very acceptable.
Kisses for Halloween
Louis

Gug, I would not change a common definition of w.v.
expains w.v.
I've made some diagrams long ago, so they may be difficult to analyze, but the definition of w.v. is relatively clear.
