Put on your red/blue glasses and gaze into this dramatic stereo view from the surface of the Moon [ http://www.badastro…]! Inspired by last Saturday's APOD [ http://antwrp.gsfc.…], experimentor Patrick Vantuyne offers this stereo rendering of Apollo 12 astronaut Pete Conrad visiting the Surveyor 3 spacecraft in November of 1969. To create the stereo [ http://apod.gsfc.na…apod_search?stereo ] image, Vantuyne carefully combed through the pictures available for downloading from the Apollo Lunar Surface Journal [ http://www.hq.nasa.…] web site to find two which would make an appropriate "stereo pair". He found [ http://www.hq.nasa.…images12.html#HiRes ] a pair that depicted the captivating scene from only slightly different viewpoints, approximating the separation between human eyes. Combining the two separate pictures, one tinted red and the other blue-green, with the correct offset, produces the stereo effect [ http://www.primenet…Stereo3D/ ] when viewed using red/blue glasses, the red filter covering the left eye. The color filters [ http://axon.physik.…color_anaglyph/ ] guide each eye to see only the picture with the correct corresponding viewpoint and the brain interprets the result as normal stereo vision [ http://www.illusion…]. ("Editor's note:" While you've got those glasses [ http://mpfwww.jpl.n…] on ... other web sources of astronomy and space science stereo images include the Mars Path Finder [ http://mars.jpl.nas…sitemap/anaglyph.htm l ] archive and a 3D Tour of the Solar System [ http://www.lpi.usra…].)
