Rabbit Holes 3D Motion Holograms Source: rabbitholes.com (site no longer online)
A RabbitHole is a 3D Motion Hologram printed into a 2-D film surface, which displays full-color 3D and action visible without special eyewear. More technically, a RabbitHole is a next-generation digital hologram that contains up to 1280 digital frames of CGI or video imagery.
These digital motion holograms are unlike any hologram you've ever seen. Classically, holograms have been single-colored or rainbow-like, and limited in their ability to realistically recreate 3D scenes, especially at a large scale; however, RabbitHoles Media utilizes patented printing technology to create bright, full-color holograms.
Three characteristics make this new communication tool unique and particularly memorable:
3D/Z-plane :: RabbitHoles are completely flat (0.7mm thick), yet the 3D imagery appears further in front of, and deeper beyond the surface than people imagine is possible.
Motion :: Using CGI (computer generated imagery) or live-action digital video, RabbitHoles can hold motion sequences up to ten seconds long to tell a short story, or bring a character to life.
Interactivity :: Viewers' movement in front of a RabbitHole triggers the immersive and animated content, provided by the image sequence embedded in the surface...up to 1280 frames!
"Unbelievable 3D! … You've got the holy grail of advertising."
The video above presents real footage of the twelve limited edition RabbitHole 3D Motion Holograms by ten renowned entertainment industry artists that RabbitHoles Media launched for the Grand Opening of Gnomon Gallery in Hollywood; the RabbitHoles 3D prints were displayed at SIGGRAPH and remain on display at Gnomon Gallery.
The pieces are printed in the amazing form of RabbitHoles state-of-the-art digital motion holograms, which display 1280 frames of full-color, 3D imagery with up to ten seconds of fluid and seamless animation on a completely flat surface. The video also includes interviews with the people pioneering the use of RabbitHoles as a new print medium for art, including artists Alex Alvarez, Fred Bastide, Pascal Blanche, Kris Costa, Jeremy Engleman, Meats Meier, Laurent Pierlot, Aaron Sims, Scott Spencer, and Timur "Taron" Baysal.
How Does it Work? Conceptually . . .
A RabbitHole works much like flip-book, with an embedded sequence of 1280 digital images acting in place of drawings on pages...using film instead of paper...and the viewers' thumbs being replaced by the viewers themselves. The digital images each provide a unique perspective of the scene or object that varies gradually from one image to the next.
Then, when viewers move back and forth in front of a RabbitHole, they literally move seamlessly through its 3D "pages"—advancing the images, shifting the perspective, and revealing the complete content by moving around freely at whatever pace they choose, with the power to play with, explore, and take part in experiencing the action.
How Does it Work? Technically . . .
Red, green, and blue pulsed-lasers are used to embed a diffraction grating within a small thickness of holographic film. Each digital image in the sequence is divided into a given number of holo-pixels using proprietary algorithms. The holo-pixels are then assigned to their necessary location amongst a given number of rows and columns.
This grid of unique holo-pixels is submitted to the Company's patented printers, which utilize red, green, and blue pulse-lasers to embed the data into the specially formulated emulsion film. The resulting prints must be front-lit from either the top or the bottom at a 45-degree angle by a direct white-light source such as a Halogen fixture or sunlight. With the white-light shining properly on a RabbitHole, the diffraction gratings bounce the light in an extremely specific wavelength, and therefore color, which allows RabbitHoles to reflect full-color images.
RabbitHoles are VERY different from lenticular technology...here is a look at the main differences:
Lenticular printing is a multi-step process consisting of creating a lenticular image from at least two existing images, and combining it with a lenticular lens; they have a ridged surface texture. Lenticulars display harsh transitions, often producing jumping, ghosted or overlaid imagery.
Lenticulars can print up to 30 frames of an image sequence, and a maximum of 1-second of transitioning imagery. Lenticulars are not made from true 3D data, they only give the illusion of having depth because they have transitional sequences. Lenticulars have very specific and limited data creation parameters.
RabbitHoles are produced by patented pulsed-laser printers, embedding data into a totally flat film surface. RabbitHoles realistically portray full-3D environments and completely fluid motion whether you want to make clean transitions, morphs, or real-life expressions. RabbitHoles can print up to 1280 frames of a rendered 3D image sequence, and contain up to 10 seconds of viewer-triggered motion or animation.
RabbitHoles content is rendered from true 3D data, and have unmatched Z-plane potential with their ability to retain focus on objects further in front of and deeper within the surface plane than any other technology. RabbitHoles can embed computer-generated imagery (CGI) as well as digital video, and can accept many common digital data forms thanks to the proprietary algorithms for the RabbitHole printers.
