The lenticular technology was developed after WWI, primarily to be used to write coded messages that could be read properly by applying a specific plastic lens to it. Since then, some of you may recall your first "lenticular experience" with items such as the toys found in a Cracker Jacks box. For instance, a small plastic piece that shows a cartoon figure with his hand down, then as you rotate it, the hand is up. Thus, with only two frames, you get the impression of someone waving by just tilting the plastic piece so it allows the lens to refract the two pictures. Since then, the technology has been driven to a point where, finally, you can image a small number of video frames to show a playback of an actual video.
For a 3D or animated effect to be made, multiple sequence of a graphic is imaged unto a photographic or lithographic print. By applying the lenticular sheet, then lens can then refract the underlying images to give either a 3D effect with perspective, or an animated playback. In real life, you are able to see true depth by using the stereoscopic ability of your eyes. The eyes are offset enough to get a slightly different angle of the same scene, thus enabling your brain to combine the two to see true depth. By rendering many different angles by moving the camera on a straight path, we are able to duplicate the view for a true perspective viewing. Stewart ComGraph, in partnership with InDepth Imaging, L.L.C. (owners of a proprietary lenticular imaging system that allows us more frames imaged onto a photo or lithographic print than anyone else at present time), have been able to produce promotional and retail products that can achieve a very high level of 3D depth to computer generated artwork (and 2D photographs). Besides 3D, we can apply this technology to video and/or computer generated animation for motion. Depending on the quality of video and type of motion, we can get up to about 4 seconds of video on our products. These products consist of extremely high-resolution images precisely aligned and bonded to a matched lens array sheet. This lenticular sheet decodes the images and plays back the desired effect to the viewer as he/she changes their position in relation to the image.
