  • The Making of Brilliance

    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)

  • How Long Has Photoshop Had a Hat Feature It

    How long has Photoshop had a “Hat” feature? It makes hats.

  • First Computer Graphics Film at T Satellite

    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.

  • Rives Bfk Acronym Explained

    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.

    This 3D thing will catch on one of these days…

  • Captain Picards Utah Teacup

    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!

    Obligatory: “Tea! Earl Grey. Hot.”

  • GelSight 3D Rubber Imaging

    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.

  • Simulated Heat Mapping for Computer Vision

    A new approach to computer vision object recognition: simulated heat-mapping:

    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?

  • Virtual Pottery Wheel

    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.

  • Structured Light

    Real-time 3D capture at 60fps using a cheap webcam and simple projected pattern of light points. The structured-light code is open source, looks like a pretty cool project.
