Lenticular technology such as printing is the use of carefully shaped and precisely engineered small lenses, usually made of plastic in the case of printing, to create the illusion of 3D or animation without the need to use special visual aids such as red / cyan anaglyphic filters, shutter based or polariser 3D glasses. A series of these small strips of lens material layed next to each other display different images when viewed at different angles by the user. Essentially, when a user looks at the image from one angle they see one image and then looking from another angle a different image appears. For the image to give the impression of being 3D, the images must be of the same object but taken from different positions [usually the width of human eyes] but with the same focal point, the lenses then provide one eye with a view of the image taken from the left position and the other eye with a view from the right. The more dense the lenses are per inch, the more accurate and effective the 3D image. The left diagram below shows a closeup of lenticular lenses on the surface of printed images and the right demonstrates in very loose terms how the technology can create the impression of depth.
