Tridentipotens (Gasperini Wiggles & Anaglyph)

In the course of conversation about Stereo 3D and Video with Dr. Frankenstein--I mean Thorndike Pickledish--I mean the estimable Robert O. Smith, we hit incidentally upon the subject of what one some time ago dubbed Gasperini Wiggles, a new type of Stereo 3D Animation pioneered and originated by Jim Gasperini, a 3D photographer (among other things) from San Francisco.

Gasperini uses the two stereo photographs from a 3D camera as two frames in sequence of a small animated .GIF, with startling results, as one may see at his site, here:

Here and elsewhere one has earlier posted examples of this new Stereo 3D, which relies on the phenomenon of persistence of vision and which needs no glasses to see the 3D effect.

Gasperini Wiggles require two renders of the object from different camera angles but focused on the same point in the object. The two images are then combined as sequence in animated .GIF. The effect varies with contrast and color, timing and size, as in the following examples:

Each of these differs slightly in focal point for the two camera angles, color, size, background, and timing.

As an experiment one could not resist combining the Gasperini Wiggle with red-blue stereo 3D anaglyphization, and the animation below is the result. It is an inward-projecting red-blue anaglyph which one looks into, while the Gasperini Wiggle effect makes the arm project outward within the inward-projecting anaglyph. You will need red-blue 3D glasses to view it--red left, blue right:

Finally, one highly recommends Dr. Frankenstein's--I mean Thorndike Pickledish's site here:

not only for anaglyphs but for video, animation, and images that are both cutting edge in Digital Art, and invariably profoundly original and comic.

Your work here is monumental !! the depth shows and the classic style leaves no remnants of vision like stereoscopic--I've seen Mr Gaspari's inventive work and I think you have used the invention in a fabulous manner....and the combo of the 'wiggle' and the red/cyan IS a first--heroic 3D work here sir...thanks for the link to Jim Gaspari's work, that is very helpful--and your images here are a triumph !
