European astronauts plan to take pics of a comet from the dawn of time
The European Space Agency (ESA) hopes to photograph a yet-to-be-discovered comet as it approaches Earth's orbit for the first time. To do so, it's developing "Comet Interceptor," a composite made of three individual spacecraft, which will separate to snap photos of the comet from multiple perspectives. The photos will be used to create a 3D model, and ESA hopes to spot material from the dawn of the Solar System.
NTT DoCoMo hands-free videophone prototype replaces that off-center webcam stare with your digital doppelganger (video)
In a sort of reverse-Project Glass, one of DoCoMo's latest prototypes flips its cameras back at the wearer. This hands-free videophone headset ties together seven separate cameras, each recording 720p video from wide-angle lenses. Aside from the single camera pointing behind the user (and beaming the background image), the rest of them point at the users' face, recording different quadrants. These are then composited together, creating a three-dimensional avatar of the user that's then broadcasted to the other caller. The model then nods, blinks, and moves -- all based on the camera footage -- all in real-time. In its current guise, the bottom half of the face is still composed from high resolution stills captured beforehand, but the program is able to animate the mouth based on the words and tones that the built-in mic picks up. NTT DoCoMo had some lighter, slight less clunky, future prototypes on show, and suggested that the headset could have medical applications, embedding further sensors that could gauge blood pressure, pulse and temperature and possibly broadcast this data during a call to your future physician. Work is currently underway to utilize smaller, higher quality sensors. We take a closer look at CEATEC after the break.
Arqball modeling app now works almost anywhere
A while ago, we covered the Arqball Spin, a special stage which, when used with an app, allowed anyone to create a 3D model of any object by rotating your iPhone's camera around it a few times. Back then, the whole thing was more idea than actual product, because you needed a special setup (so your iPhone could line up and see what you were modeling at exactly the right angle). However, Arqball has now released a new version of the app, and it's a lot more adaptable. You can now use essentially any rotating stage (from a record turntable to a lazy susan), and the free app will let you capture and model almost any object. There's also a beta version of the app out for Android as well (though that doesn't matter much to us iOS users), and Arqball is also working on a feature that would let users import video of a spin from somewhere else, for example a higher quality DSLR, and/or share finished spin videos out to anyone else. The details on that aren't final yet -- Arqball says sharing may require an extra service fee of some kind. But clearly the tech is moving forward. In the future, getting a 3D view like this may be as simple as just taking a few pictures yourself.
Autodesk launches 123D Catch for iPad, lets you turn pics into 3D models
Autodesk's had its 123D Catch iPad application in the works for quite some time now, but starting today, you'll finally be able to use that Cupertino slate to turn those beautiful snaps into three-dee creations. Similar to its desktop counterpart, the 123D Catch app won't cost a dime, and it's compatible with the second and third-gen iPads. To go along with the application, the company's also introducing its "MyCorner" cloud locker, which will let users store their pictures as well as share them between other Autodesk 3D apps. You can grab 123D Catch from the iTunes link below or via the app shop on your iPad. There's also a video after the break for your viewing pleasure.
Qumarion 3D modeling mannequin coming soon for $750, still won't play with your kid (video)
Trying to get convincing, natural poses out of 3D models can be tricky, so it's a relief that two Japanese universities' joint ventures, the University of Electro-Communications' ViVienne and the University of Tsukuba's SoftEther, are close to wrapping up work on their posable mannequin. Now called Qumarion, the model formerly known as QUMA uses 32 sensors across 16 body joints to translate the humanoid statue's pose to the computer screen simply by bending limbs, much like you would the legion of action figures you had when you were eight. Neither you nor your kids will be using Qumarion to storm Fort Barbie anytime soon, but the 120 frames per second sample rate over USB does mean that poses are mirrored in your modeling tools almost instantly. You also won't have much longer to wait to buy one for your fledgling anime production: the mannequin and custom modeling software from Celsys should be bundled together sometime within the summer for a comparatively frugal $750.
New iOS app allows anyone to make 3D model from real object
Arqball Spin is a strangely-named iOS app that does something pretty magical: It will create fully spinnable 3D models from real-life objects. The app is available to download right now, so you can go and check it out for free. Engadget played with both the app and a stage (more on that in a second), and they have examples and video of how the app works. The model looks pretty great, even just viewed in a web browser. Basically, the app uses your iPad to take a series of pictures of an object, and then assembles those pictures into a "rotatable" model, essentially faking 3D (sort of similar to those old shots from The Matrix, where a series of cameras took a sequence of rotational photos that were then stitched together). The catch is that obviously all of those photos need to line up as exactly as possible. While (presumably) you could just hold your iPad in place, you'll get a rough result that jumps around in the frame, unless you get exactly the right angle every single time. To counteract this, Arqball is selling "stages" over on Kickstarter, which precisely holds and rotates your object. If you don't want to get involved in the Kickstarter (or just outright buy one after it's been funded, for $80 rather than $60), you can even make your own stage, as long as it rotates your object at the right speed. At any rate, it's a great idea, and it could mean some big things for 3D modeling in the future. We've also seen the iPad used to create 3D models that can then be printed, so someday, you might take a series of pictures of an object with your iPad, and then hook that up to a 3D printer to get a copy of that object for yourself. Very cool indeed.
Hands-on with Arqball Spin, the app that lets you create interactive 3D models
Sometimes, standard two dimensional photos, even those taken by a 41-megapixel sensor, simply aren't enough to accurately depict a three dimensional object. Enter Arqball Spin, a free app that lets anyone with an iOS device create high-quality 3D models of whatever they like. Using the iPhone's camera, the app takes a series of images and uses some software black magic to create the finished product. The model, or "spin", can be cropped and adjusted (brightness, saturation and contrast) like a regular photograph, plus users can create custom annotations to identify or comment on specific parts of the "spin" as well. Viewers can then rotate the model 360 degrees and zoom in on any part that piques their interest. While it's currently an Apple-centric affair, support for DSLRs and other hi-res cameras (by uploading videos to the company's website for processing) and other mobile platforms is in the pipeline. The app works best if the object is situated on Arqball's stage, which rotates at an optimal three RPM -- the stage isn't available yet, but the company's going the Kickstarter route to get the capital needed to start manufacturing. Those who pitch in now can grab a stage for $60, and it'll cost $20 more if you want to wait until it's on sale. Of course, the app still functions if you want to hold your iPhone or iPad and walk around your subject, but you won't get near the quality result that you can when using the stage. Because the "spins" are hosted on Arqball's servers, they can easily be embedded on any website via HTML. By making photo-realistic 3D modeling so easy and accessible, Arqball sees this technology as a perfect fit for online retailers, educators, and, ahem, even gadget reviewers. While the app holds obvious commercial appeal, the company's not counting out casual users, and hopes to see a future filled with user-created 3D content. We got to see the app in action, and walked away thoroughly impressed with both the speed of the app and the detailed models it produces -- but you don't have to take our word for it, see a sample spin and our hands-on video after the break.
Visual Spicer creates a 7-foot tall papercraft Gundam, films the entire process as a timelapse (video)
Believe it or not, the massive seven-foot Gundam you're looking at was mostly constructed out of paper -- 720 sheets, to be exact. The papercraft artist behind the model, Taras Lesko (aka Visual Spicer), began creating it nearly a year ago, and estimates that it took him about 350 hours and four to five months to complete. As explained on his video commentary, the process started with building a store-bought model for photographs, using the shots to render it in 3D on his computer. After that, he created various templates using a variety of programs, which were then printed, cut and assembled into place. Notably, the final product has 1,250 total parts, weighs in at about 10 pounds and packs an internal 12-piece foamboard skeleton to stand. All of that is only the part of the final product, though. Taking it a few steps further, he created a bevy of "fantasy shots" (like the one above) with his brother, Ivan -- and of course, Photoshop -- and even filmed both endeavors as timelapse videos. According to Taras, the aim was to make something "bigger and better" than the four-foot papercraft Gundam, which he made nearly three years ago and burned to ashes on video prior to this project -- we'd say mission accomplished. You'll find the construction timelapse video after the break, along with more related vids and photos at the source link below. [Thanks, Christos]
Visualized: Objet's 3D printer breathes plastic life into Hollywood creatures, layer by layer
It ain't easy being plastic, you know? Objet -- the 3D printing house that aimed to replace your office's all-in-one Epson back in July -- brought a few of its snazziest pieces here to SIGGRAPH, and we popped by to have a gander. Targeting the animation-inspired crowd that showed up here in Vancouver, the company brought along some Hollywood examples of how its multi-material Objet260 Connex helped movie makers craft prototype creatures before they were inserted into the storyline. Thor's Destroyer and Avatar's Na'vi were both on hand, as well as the two critters shown above. The hothead on the right was crafted in around 18 hours (and subsequently painted), while the cool cat on the left was built in three fewer. Wildly enough, that fellow required no painting whatsoever; so long as you're cool with shades of grey, you can program your object to be colored from the outset. Oh, and as for his cost? Around $80 for the materials -- slightly more for the printer itself. %Gallery-130291%
Microsoft application creates 3D model using a cellphone, blows our minds
Using your smartphone to take regular, or heck, even 3D images, is so last-gen -- thanks to Microsoft's Interactive Visual Media Group, we shall soon be able to use its new app to generate virtual 3D models. For example, if you want to capture that Ferrari on your neighbor's driveway, you'll need to circumambulate it while shooting around 40 photos. The final product, which is compiled using some beefed up PhotoSynth magic as each shot is uploaded to the cloud, is a beautifully crafted 3D model that can be panned around surprisingly smoothly. Hit play on the video below to feast your eyes on Redmond's new trick. [Thanks, @scienceben]
VideoMocap creates 3D animation from any 2D clip (video)
If you've ever used a video editing program, you might be familiar with the concept of "keyframes," which define the beginning and end of a particular segment. Seeing where you came from and where you're going, the computer literally guesses what's in between, and creates smooth animation as a result -- the very same technique that students at Texas A&M University use to create motion capture that doesn't require arrays of cameras or ping-pong balls. Dropping the laws of Newtonian physics into their algorithms, Xiaolin Wei and Jinxiang Chai claim to have whipped up a computer program that can turn most any 2D video into simple 3D animation in real time, with just a few keyframes to start out. For instance, in a complex weightlifting segment 310 frames long where the camera panned, tilted and zoomed, animators had only to position eleven joints in thirteen keyframes (and make seven minute adjustments) to get the entire animation to turn out. See it in action after the break, or read their entire SIGGRAPH paper at our more coverage link.
Researchers aim to give surgeons 3D maps, directions of human body
While a GPS-style "navigation system" for surgeons may not seem like the best idea to anyone that's ever been led astray by their dash-mounted co-pilot, it apparently seemed like a good enough idea for a group of researchers at the University of Twente in the Netherlands. While they do stretch the metaphor a bit, the group's TLEMsafe system does provide surgeons with a complete 3D map of the lower body, which can actually be personalized for each individual patient, giving surgeons a reference and means to practice before any actual surgery takes place -- and, yes, even an "automated navigation system" during surgery. Coincidentally, some researchers from the University of Colorado have also just announced that they've developed a similar modeling system that would give surgeons 3D views of arteries and let them see any blockages up close. It's even already been tested on patients, while the University of Twente says its system will be ready for clinical trials in about four years' time.
