Ciao!
I remember from some book that for the Moon enough a base 1x Earth diameter.
...and I remember that Wojtek has a 3D moon without any distorsion....
Ciao Imre,  Yes, this depending of the time shoot between two frames during Moon libration but picture bellow with the two Moon was with an excessive stereo base needed correcting.



Artifact also this conversion  with a over spherical volume, but pleasant, sent on French 3D list by Pierre Meindre, but I don't know who do it !

Your corrected version soffers of the distorsion artifacts....
I agree: this is a very very hard issue and job....

Great!
But seems to me Moon and Mars are too spheic....must be viewed with big HFOV.
Imre


Yes Imre, you are right... I already made correcting with Photoshop bellow on a real shoot giving an egg volume (all distort volume for stereo are hyperbolic).
   Could you imagine the stereo base to got the Moon on the right bellow is corresponding (because use of libration) +/- three time the Earth diameter, so our poor eyes space could never see the Moon like that same as in a pace 
   ship. If I was in space so fare from the Moon (half distance Earth / Moon) with my small eyes space... I think I will see only a disc, not a sphere (in a plane at a certain distance we don't see the ground in relief but in 2D), so if I  
  apply like human vision will see the Moon in space I have to use 2D and let my brain imagine it is a sphere ;)

but if you was in space with your narow eyes space it will not be possible witht this distance to see something eles than a disk

Hi, Some months ago I shoot my IPAD  with Google Mars program and also with Google Moon program (Google Earth too of course), you have just to turn gently a bit with your finger the planet or the moon to permit a twin shoot for "stereoscopisation".
There is so many programs and 2D movies to permit stereo-extraction. But with Google I believe relief is false for some ! (see Pict "Mars07 canyon)
On 2D movie it is also so easy to detect possible stereo-extraction with Pulfrich glasses. Use of Pulfrich glasses also possible on Ipad, Iphone, if you found a good rotational speed with help of your finger.

3 types of Pulfrich glasses. Such glasses permit to detect possible "stereoscopisation"
and of course to see such 2D movie  (the scene detect with Pulfrich glasses) on  3D-TV having a 2D to 3D conversion circuit (using also Pulfrich before "stereo-transfer" for active or passive glasses) give a good stereoscopic result.





Try on Google Moon... with zoom on (cut necessary now)




Jm
