The last time we discussed this, I think, was around the time of the UMSF balloon flight. The idea was to use images of clouds obtained at intervals fom an ascending balloon as stereo pairs. Horizontally separated successive images from a plane could potentially work the same way. I think someone (ugordan?) had a go at doing this. IIRC the enemy was - time. The clouds changed too much in the time interval necessary beween shots for good 3D images to be obtained.

But now we have the marvellous HDEV from the ISS, a very fast moving platform! Images separated by just a few seconds should be wide enough apart to use for 3D without the clouds themselves having time to change significantly. I can imagine a split screen view from the downward pointing camera, with a short delay on one side relative to the other. Viewing this as cross-eye should generate a 3-D movie showing not only clouds but also mountains rising upward toward the viewer.

Of course I haven't a clue how to accomplish this but I bet there are a few folks here who could, or maybe even have already. Does anybody else think it might be worth a go?

Take a couple of screenshots a few seconds apart and try it.

I had a go a few weeks ago basically without success.
