Fabricated: Scientists develop method to synthesize the sound of clothing for animations (video)

Fabricated Scientists synthesize the sound of moving clothing, but you'll still need the Wilhelm Scream

Developments in CGI and animatronics might be getting alarmingly realistic, but the audio that goes with it often still relies on manual recordings. A pair of associate professors and a graduate student from Cornell University, however, have developed a method for synthesizing the sound of moving fabrics — such as rustling clothes — for use in animations, and thus, potentially film. The process, presented at SIGGRAPH, but reported to the public today, involves looking into two components of the natural sound of fabric, cloth moving on cloth, and crumpling. After creating a model for the energy and pattern of these two aspects, an approximation of the sound can be created, which acts as a kind of “road map” for the final audio.

The end result is created by breaking the map down into much smaller fragments, which are then matched against a database of similar sections of real field-recorded audio. They even included binaural recordings to give a first-person perspective for headphone wearers. The process is still overseen by a human sound engineer, who selects the appropriate type of fabric and oversees the way that sounds are matched, meaning it’s not quite ready for prime time. Understandable really, as this is still a proof of concept, with real-time operations and other improvements penciled in for future iterations. What does a virtual sheet being pulled over an imaginary sofa sound like? Head past the break to hear it in action, along with a presentation of the process.

AT&T’s Cutting-Edge Computer Graphics Workstation Looked Outdated Even in 1982 [Video]

Before the internet as we know it came to be, there were other services that delivered news and information to homes via computers and TVs. Like AT&T’s failed Viewtron system, which required content creators to shell out $34,000 for this Frame Creation Terminal that produced crude computer graphics even by Mario Paint standards. More »

Watch a Building Animate Itself Like a Computer Screen [Video]

This building’s animation might look like it’s computer generated but it’s actually done with good ol’ fashioned human hands. Literally. People are inside each room and shut each window to create a building wall that looks like pixels. More »

How 3D printing changed the face of ‘ParaNorman’

How 3D printing changed the face of 'Paranoman'

We drive around in circles trying to find the place. There’s no signage indicating our destination — no giant, looming cartoon characters or even a logo, just a faceless building in a maze of industrial parks, about 17 miles outside of Portland. It’s a beautiful drive of course, sandwiched on a vaguely winding highway by dense Pacific Northwest foliage, past Nike’s global headquarters. Compared to the world-class tracks and fields dotting the shoemaker’s campus, Laika’s own offices are an exercise in modesty (in spite of financial ties Phil Knight), virtually indistinguishable from the densely packed businesses that surround it. There are, perhaps, certain advantages to such anonymity — for one thing, it helps the studio avoid random drop-ins by movie fans hoping to chew the ear off of their animation heroes. It also means that our cab driver does a good three passes before finally getting out of the car and asking a smoker standing outside a nearby building where to go. He thinks about it for a moment and indicates a building — a large, but otherwise indistinguishable space.

The lobby doesn’t scream Hollywood either, but it certainly offers some less-than-subtle hints that we’ve found the place: a wall-sized black and white image of classic film cameras (ancient devices, someone tells me, that were utilized on the company’s previous film), and in one corner, a tiny room encased in glass, with Coraline seated at a table in its center. This building is the house that she built — or at least kept the lights on; “Coraline” was released after its planned successor “Jack & Ben’s Animated Adventure” failed to materialize. Inside, the cavernous space in excess of 150,000 square feet has become a bustling small town of creatives, laboring away in its recesses, many having traveled through several time zones to be in its rank, like carnies hopping from town to town. Stop-motion animation, after all, isn’t the most prevalent of professions, and while we’ve arguably entered a sort of golden age for the infamously labor-intensive art form, thanks in large part to the success of projects like “Coraline,” the number of studios actually investing in the form can be counted on one hand.

Scientists create simulation of the universe, reenact 14 billion years in a few months (video)

Scientists create simulation of the universe, reenact 14 billion years in a few months

Are animations of Curiosity’s Mars landing not enough to feed your space exploration appetite? Try this on for size: a group of scientists from the Harvard-Smithsonian Center for Astrophysics and the Heidelberg Institute for Theoretical Studies have generated what’s billed as a full-fledged simulation of the universe. Arepo, the software behind the sim, took the observed afterglow of the big bang as its only input and sped things up by 14 billion years. The result was a model of the cosmos peppered with realistically depicted galaxies that look like our own and those around us. Previous programs created unseemly blobs of stars instead of the spiral galaxies that were hoped for because they divided space into cubes of fixed size and shape. Arepo’s secret to producing accurate visualizations is its geometry; a grid that moves and flexes to mirror the motions of dark energy, dark matter, gasses and stars. Video playback of the celestial recreation clocks in at just over a minute, but it took Harvard’s 1,024-core Odyssey super computer months to churn out. Next on the group’s docket is tackling larger portions of the universe at a higher resolution. Head past the jump for the video and full press release, or hit the source links below for the nitty-gritty details in the team’s trio of scholarly papers.

Disney researchers can now digitally shave your face, clone it for animatronics (video)

Disney researchers can now digitally shave your face, clone it for animatronics video

The minds at Disney Research aren’t only interested in tracking your face — they want to map, shave and clone it, too. Through a pair of research projects, Walt’s proteges have managed to create systems for not only mapping, digitally reconstructing and removing facial hair, but also for creating lifelike synthetic replicas of human faces for use in animatronics. Let’s start with the beards, shall we? Facial hair is a big part of a person’s physical identity, a quick shave can render a close friend unrecognizable — but modern face-capture systems aren’t really optimized for the stuff. Disney researchers attempted to address that issue by creating an algorithm that detects facial hair, reconstructs it in 3D and uses the information it gathers to suss out the shape of the skin underneath it. This produces a reconstruction of not only the skin episurface, but also of the subject’s individual hairs, meaning the final product can be viewed with or without a clean shave.

Another Disney team is also taking a careful look at the human face, but is working on more tangible reconstructions — specifically for use on audio-animatronic robots. The team behind the Physical Face Cloning project hope to automate part of creating animatronics to speed up the task of replicating a human face for future Disney robots. This complicated process involves capturing a subjects face under a variety of conditions and using that data to optimize a composition of synthetic skin to best match the original. Fully bearded animatronic clones are still a ways off, of course, but isn’t it comforting to know that Disney could one day replace you accurately replicate your visage in Walt Disney World for posterity? Dive into the specifics of the research at the source links below, or read on for a video summary of the basics.

LCD Zoetrope Is a Beautiful Update To an Antique Toy [Video]

Before YouTube, TV, and even the movies, people were genuinely entertained by a device called a Zoetrope that played simple looped animations while it spun. The animations were created on strips of paper that were placed inside the inner circumference of the device—a process that’s been made considerably easier with the Pristitrope’s array of tiny LCD displays.

This Could Be the World’s First Computer Generated Animation [Video]

It’s almost impossible to pin down when and where the first computer animation was created, given several companies and research facilities were dabbling in the new medium at the same time. But AT&T—formerly Bell Labs—and others believe this simple clip dating back to 1963 could indeed be the world’s first CG animation. More »
