That was pretty cool. I wonder how they make the images, by hand or some automated algorithm that takes a few-framed movie and prints it up.

- paraschopra 17y agoLooks like an automated algorithm to me, probably based on some vision research. Lack of a link with more details bothered me as it was a pretty cool hack.
- teaspoon 17y agoIt's a simple algorithm, and you could carry it out by hand in an image editor without much difficulty. Just overlay N layers (the frames of your animation) on top of one another. For every Nth column of pixels, delete the next N-1 columns following it (in all layers). Then, for each layer at index X in the stack, translate the entire layer horizontally by X pixels. Your overlay for viewing the animation is just a black opaque rectangle with every Nth column being deleted to reveal the image beneath.
- qwzybug 17y agoI think you need one more variable in there, but yeah that's the right idea :)
- LarrySDonald 17y agoLooking at it, yes, that's pretty much it. Lenticular images (aka, sports flips, those odd things that move when you tilt them, etc) are based on the same principle except with a lens to show each "band" depending on viewing angle rather then moving a striped sheet over it to obscure a sequence of frames.
