You eyes provide decent 3d, don't they?

  Yes, over small scales and distances. Say you want a stereogram that shows you Manhattan or the Grand Canyon as if it were a model laid out on a table before you. A human-like stereoscopic shot of those places will not produce the depth. (Maybe something can be computed, but that's a separate discussion.)

    Just use 2 normal cameras with 1 meter separation. There are some videos on deovr/quest with this kind stereo effect; for example clouds filmed from a airplane, they look like toy 3d clouds.

      I've taken stereograms of clouds from an airplane. This is done just by taking consecutive shots out of the same window from the same angle, as the airplane flies. So you have probably hundreds of meters of separation. At 900 km/h, if you take two shots one second apart, that's 250 meters. Of course the resulting stereogram is perceived as a wonderful miniature. To make a 3D film this way, just take a regular video, and then split it into offsets. Well over a decade ago, someone in Japan turned some old videos of the Candies idol group (1970s) into 3D this way, e.g.: https://www.youtube.com/watch?v=wqBL08JOM0I https://www.youtube.com/watch?v=wqBL08JOM0I Needless to say, the original footage was not shot with two cameras; it's just a time offset in the same video stream. Due to the motion of the performers or camera, you get faked out stereoscopy. To find more of these, search: youtube キャンデイーズ 3D
