*A.G* Posted August 21, 2011 Posted August 21, 2011 theres a sqaure within a square that is spinning in a 75 degree angle causing it to look like the square is constatly comming out of the square. good illusion Quote
rolf Posted August 29, 2011 Posted August 29, 2011 This is not a real optical illusion, it's just an example of the problems you'll have when displaying a figure onto 2D. For a 1D 'square' (line), all lengts are equally long For 2D square, this is still possible on a computer screen. For 3D cube, it is already not possible to give each line the same length. However, due to the fact that people can imagine depth, we don't see a problem with that (otherwise ET/CoD would be boring). And how to demonstrate a 4D cube (tesseract, as in the picture)? You combine the 3D with movement. You must understand that each length is equally long. Since there's no tesseract in real life that has these properties, we cannot imagine it anymore. If, instead of seeing it as a picture, but understant the definitions, it's quite easy, even tho it is never possible IRL Quote

PiNoY Posted August 30, 2011 Posted August 30, 2011 its the lights of those rotating square bars that makes that...oh what did i say? i cant digest that one. sorry. Quote
rolf Posted August 30, 2011 Posted August 30, 2011 Please, define an optical illusion for me. Good point However, this image has never been made to be a optical illusion, but as an optical explanation. Instead of your other (many of them awesome, I must say) pics Quote
