[edit] Summary

This is a "wiggle-gram" that combines and animates two images of the same scene taken by Spirit's stereoscopic cameras, giving an approximate sense of the actual depth in the scene. Shown is a weathered, layered rock near the edge of the "Home Plate" circular structure. Of artistic curiosity is the Salvador Dalí nature of the rock. (It may take a while for both images in the animation to load before the animation movement appears, which uses the "animated GIF" file format. Images used are NASA/JPL images taken by the Spirit rover.) --Tablizer 05:06, 21 March 2007 (UTC)

[edit] Comments

The 3D effect of this image would be greatly enhanced by increasing the speed at which the frames switch back and forth. Also, perhaps a less extreme difference between each frame, but that's probably impossible (unless more pictures were taken, I guess). Twisket 05:09, 25 February 2007 (UTC)

I disagree about more "flip speed". But it may be subjective. Too fast and you can't see the detail. It may be a trade-off between perceiving detail and the stereo affect. I leaned slightly toward the detail side. You are welcome to experiment with different speeds and perhaps post them under the "discussion" tab for comments. I've seen how the insertion of an artificially-generated composit "in between" image helps, but it is best to keep that one short, or it ruins clarity, at least to me. There were only 2 frames from the probe, one for each "eye". The only way to get more (real) in-between images is for the probe to incrementally move a bit and then shoot the same scene multiple times. This does not appear to be a commonly-used activity of the probes. Also notice how I made one frame's duration slightly shorter than another. This is a compromise technique between fast swapping and detail: one fast and one dweller. -submitter- --Tablizer 05:07, 21 March 2007 (UTC)
