Stereo effect (APOD 12 Dec 2006)
Posted: Mon Jan 01, 2007 3:44 am
I would have put this into the other Dec 12 thread, but it has been hijacked by the manned/unmanned perennial discussion.
To the subject:
I was looking at the Dec. 12 comparison pictures of the "water flow" and did what I often do when I am comparing two pictures. I crossed my eyes and fused the images.
Imagine my surprise when the crater stood out in 3D! The images must have been taken from just enough different locations to give the effect.
Looking at it in 3D, it is obvious that the white deposit has little or no relief, as would be expected. However, it is also obvious that there is something else going on in the picture, in the upper left corner, where it looks as if a sinkhole has deepened.
