Le Forgeron example:
camera
{ stereo distance (26)
parallaxe atan2(13,300)
location -300*z
right image_width/image_height*x
direction z
up y
angle 15
}
My exporter:
camera {
stereo distance (???) //It is calculated the exporter or is declared by the
user?
parallaxe atan2(???,???) //It is calculated the exporter or is declared by
the user?
location <0,0,0>
look_at <0,0,-1>
right <-1.7777777777777777, 0, 0>
up <0, 1, 0>
angle 49.134343
rotate <-27.098163, 46.688390, -0.903519>
translate <7.481132, 5.343666, 6.507640>
}

It's the distance between the eyes.
It's about 13 cm usually, for adult human at least.
I do not know if you have a scale setting for your scene. (something like: 1 pov unit
= x.xxx meter )

If you have a "focus" point, it might help.
Focus point is on the line from 'location', along 'direction'.
Here attached is an illustration of distance and parallaxe.
Value of parallaxe is in radian.
It's the angle away from the direction vector for each pseudo-center for the image of
each eye.

@LanuHum: Don't listen to him -- the French are known to be freaks.
Normal people have about half that inter-pupillary distance ;)

You are probably correct... I do not know where I picked that 13 cm.

It is the metric system. It can be confusing. ;-)

[making a facepalm]
Yes, especially when you know that that distance is exactly 1 palm. :-)

It may seem counter-intuitive but because the imperial system is not
regular. More thought was needed and results were passed through a
mental double check. Today youngsters can't count.

I understood that manual input is necessary.
omni_directional_stereo and fisheye_stereographic these parameters require???
Thanks.

omni_directional_stereo needs only "distance" (same meaning as for "camera stereo").
fisheye_stereographic is single point of view (blame the historical naming): no stereo
vision there.
(and no "distance" and no "parallaxe"). It's a fisheye, with a specific curve for
mapping.
