Stereo animations of the five Platonic solids. Using rotation, folding/unfolding animation and translucency combined with the possibility of stereo vision, they make the structure of the Platonic solids (which laymen often have difficulty understanding, particularly the Dodecahedron and Icosahedron) very clear, justifying use as Valued Images for the scope "The Platonic solids". Note: Non-IE browser or dedicated viewing program strongly recommended for viewing. IE doesn't display high-quality animated GIFs smoothly.
Support - Though I found it impossible to get the stereo effect at full resolution, these are clearly useful images, even if you don't get the stereo effect to work. Adam Cuerden (talk) 16:22, 16 August 2009 (UTC)[reply]
It's a matter of viewing distance. The angular displacement between the two images is 0.1/2*Pi, and with the distance between the two image centers being around 8cm, this yields an optimal viewing distance of roughly 50-70cm depending on the distance between your pupils (just updated the description page, was calculated for small res before). I myself can see the stereo effect at all distances instantly, but as mentioned on w:Stereogram, some people need the "finger trick", and some simply cannot decouple their eyes and will sadly never see 3D (like Daniel78 for example, as he wrote here). In general though, the further you are away from a stereogram, the easier it is to see the effect, even though with increasing distance the picture loses depth. -- JovanCormac17:56, 16 August 2009 (UTC)[reply]
