In 1985, computer graphics were exotic enough that using them for a TV commercial was the kind of thing you might save for a Super Bowl ad slot, as seen in this short documentary. I would not have guessed that the first significant use of CGI on TV was for an ad illustrating the sexy (?) futuristic appear of _aluminum cans_.
(They fail to mention this in this mini-doc, but the ad studio was clearly lifting the chrome-plated sexy robots imagery of Japanese illustrator Hajime Sorayama)
Now that I have a retina display, I want a screensaver that looks as good as this 1963 AT&T microfilm video:
This film was a specific project to define how a particular type of satellite would move through space. Edward E. Zajac made, and narrated, the film, which is considered to be possibly the very first computer graphics film ever. Zajac programmed the calculations in FORTRAN, then used a program written by Zajac’s colleague, Frank Sinden, called ORBIT. The original computations were fed into the computer via punch cards, then the output was printed onto microfilm using the General Dynamics Electronics Stromberg-Carlson 4020 microfilm recorder. All computer processing was done on an IBM 7090 or 7094 series computer.
As an art person I’ve enjoyed a good amount of time around lithography and other drawing media, and now I’m engaged to a children’s book illustrator who largely works in watercolor, so I’ve spent a fair amount of time at art supply shops buying paper. One thing has bugged me for years about our fine rag paper purchases, though: what’s up with the “BFK” in “Rives Arches BFK”? I’ve asked professors, professional printers, other artists, and even the Internet, with no great leads, but I finally coaxed the answer out of Google today. From The Albumen & Salted Paper Book: The history and practice of photographic printing, 1840-1895:
It is no wonder that only two paper mills in the world managed to consistently produce a paper of the necessary quality, and these two mills were able to maintain their monopoly from the 1860’s until approximately World War I. They were the above-mentioned Blanchet Frères et Klébler Co. in Rives, France (hence their product was known as the “Rives” paper) and Steinbach and Company, located in Malmedy, Belgium (at that time part of Germany). Steinbach paper was known outside Germany as “Saxe” paper.
The product that established their paper monopoly (duopoly?) — the exploding new field of photography! More to the point, 3D stereography, the Victorian postcard origin of a Tumblr meme:
In the late 1850’s and especially after 1860, two new factors in photographic technology and practice generated a great demand for albumen paper. The first of these was the stereograph; its ability to transport the viewer to distant scenes with the illusion of three-dimensional reality depended largely on the smooth surface and fine detail of albumen paper. Stereo views were extremely popular, and created a corresponding demand for albumen paper. Nearly all stereo views before 1890 were made on albumen paper.
As the Make post says, this 3D-printable model of Captain Picard’s teacup would be a good benchmark for the nascent fabrication technology (the image on the right is a photo of the original Star Trek prop, which was just an off-the-shelf Bodum teacup). That it could be seen as a sly progression from the famous Utah teapot I think makes it an especially worthy benchmark!
GelSight, a high-resolution, portable 3D imaging system from researchers at MIT, basically what looks like a small piece of translucent rubber injected with metal flakes. Watch the video to see some of the microscopic scans they’re able to get using this. I love non-showy SIGGRAPH tech demos like this one.
The heat-mapping method works by first breaking an object into a mesh of triangles, the simplest shape that can characterize surfaces, and then calculating the flow of heat over the meshed object. The method does not involve actually tracking heat; it simulates the flow of heat using well-established mathematical principles, Ramani said. …
The method accurately simulates how heat flows on the object while revealing its structure and distinguishing unique points needed for segmentation by computing the “heat mean signature.” Knowing the heat mean signature allows a computer to determine the center of each segment, assign a “weight” to specific segments and then define the overall shape of the object. …
“A histogram is a two-dimensional mapping of a three-dimensional shape,” Ramani said. “So, no matter how a dog bends or twists, it gives you the same signature.”
In other words, recognizing discrete parts (like fingers or facial features) of an object in front of the camera should be much more accurate with this approach than with older techniques like simple edge detection. Uses for real-time recognition are apparent (more accurate Dance Central!), but it seems like this would also be a boon for character animation rigging?
L’Artisan Electronique, an openFrameworks-powered “virtual pottery wheel”. Users can deform the cylinder geometry by waving their hand between the lasers and then print a physical copy of their piece using an attached RepRap machine.
If you’re the sort of lab that’s engineering a method of printing ceramic materials using rapid prototyping machines, I suppose it’d make sense that you’d already have made some real-life polygonal Utah teapots! I never thought about it before, but for the 3D graphics humor value I really, really want one of these now. You can read about the Utanalog project and see finished photos (and a video explaining the whole thing) over on the Unfold blog.
Pretend to be Radiohead with this Instructable guide to 3D light scanning using a projector, camera, and a bit of Processing! This is designed to create the visualization seen in the video above, but you could also use the point data for output on a 3D printer, animation package, etc. Neat.
“Touchable Holography”, a hardware demo by researchers from the University of Tokyo at this year’s SIGGRAPH conference. This mostly builds on the work they presented last year involving their “Airborne Ultrasound Tactile Display” (PDF), a device that shoots out directional ultrasound to simulate haptic pressure, like the impact rain has when it hits your skin. I don’t think this current display counts as holography exactly (the image is made with a refracting mirror, just like Sega’s 1991 arcade game Time Traveler!), but being able to reinforce the illusion with the sensation of touch is a cool idea. Hopefully they can expand it to use more than one of their ultrasound boards so they can simulate a feeling that’s more than one-dimensional. Also good to see that researchers are using the inexpensive, off-the-shelf Wiimotes for projects like this.
Rhonda. It’s a nifty 3D drawing/sketching app that’s been making the rounds for a few years, and now the video of its creator sketching with it has finally been posted on the web. Even better: it’s been ported to openFrameworks and is being actively maintained on a number of platforms.
