Hello i was wondering if anyone knew the name of the process used to create the 4d images like in shrek4d, when not wearing 3d glasses there is a red and blue ghosting effect that causes the 3d effect, is there either an application or advice on how to apply this 4d effect to existing images or animations, any advice tips or research links to this topic would be greatly appreciated. ideally i would like to find an application that will let you drop existing images or film into it and presto at the click of a button is a 4d image, Im probably dreaming though lol,
