Would this require stereo panos? Would those need to be side-by-side or top-and-bottom?

I believe he said it takes stereo renderings, but also that you have to copy-paste half of the left cam onto the right cam and vice-versa otherwise while you are looking left the images are flopped right, and vice-versa... I think Jo-ke can explain better.

yes stereopano., one for each eye

I think I have to make a plan to explain how it can work...

at first set the point of Pano SU.

if you turn your head 90 degrees the perspective changes.

180 degrees is the same than 0 degress but left and right are changed.

same is 90 and 270 degrees.

So we need 4 panos. each 3,5 cm to the point in the middle.

they have to be stiched in different ways.

I'll prepare some examples...

The KT render engine doesn't support rendering multiple cameras simultaneously. The best we could do is a kind of automated way of setting up a batch render of 2 renders with the eyepoint offset by a certain amount. Combining the two images would have to be done in post-processing.
