3D Mars Stereograph
3D Mars Stereographs is a real neat way to see a 3D image of the mars land rover. When you stare at the image make your eyes go slitely cross eyed until the two images merge to form a center image, you will have your 3D version. Anohter method is to put your nose cloce to the image and slowly move away, althoe i find the first method works almost instantly for me! so try it out!
Regarding the Mars 3D image pair, the correct way tho view this particular pair is via the 2nd method you mentioned (parallel eyes), not cross-eyed. Rule: The proper naked eye free-viewing method to use (cross-eyed or parallel), depends directly upon the L/R or R/L placement of the 3D image pair. A L/R arrangement MUST be viewed with the parallel method, while an R/L arrangement MUST be viewed with the cross-eyed method. If not, the 3D effect is “backwards”; far becomes close, and vice versa, a very odd effect. The Mars pair is L/R and must be viewed with the parallel method where L-eye sees L-image, and R sees R. Though more difficult to master than the cross-eyed method, parallel viewing is superior for one very important reason — with this method, the 3D object appears “normal” in size on the screen. Cross-eyed viewing, however, gets interpreted by the brain in an interesting way; The 3D image exhibits the “Lilliput e
ffect” whereby the image and the objects within it appear miniaturized. Swap the 2 images left and right and the 3D-cross-eyed-with-Lilliput-effect will be visible.
