Are there any 360° camera with 2 or more lenses and have a common nodal point for all the lens?

Is it "theoretically" possible to build such a camera, so there will never be a stitching error?

Why would the nodal point affect stitching errors, as the image captured at the periphery is essentially parallel to the sensor plane on a 2 lens camera?

Isn't it more important to reduce the distance between the lenses (which is what the more recent 360 degree cameras all do)? I would have thought that was the reason why (some) more recent cameras stitch better.

PARALLAX is the main problem !

That's all the same thing.

The plane created by all points 90° of the the lens (as seen through the lens) crosses the view axis through the nodal point. The distance between those plains causes the parallax and is the distance between the nodal points. To have minimum parallax you have to bring the nodal points as close together as possible which means to bring the two lenses as close together as possible.   With the ideal two lens 360° camera you always have a parallax of 0° for all points visible by both lenses which means those plains are the same and you have one common nodal point. But as we have already discussed this is physically not possible.
