Google's 3D scans recreate historical sites threatened by climate change
Google is no stranger to reproducing historical sites online, but it's now pushing technical boundaries to recreate those sites at risk of vanishing due to the ravages of climate change. It's launching a "Heritage on the Edge" collection in Arts & Culture that will include over 50 exhibitions illustrating the effect of an evolving climate on historical landmarks, including five locations recreated in detailed 3D (with 25 models total) using a mix of scans, photogrammetry and drone footage. You can see vivid depictions of the statues at Easter Island's Rapa Nui, the Old and New Towns of Edinburgh, the trading port of Kilwa Kisiwani in Tanzania, Bangladesh's Mosque City of Bagerhat and Peru's ancient city of Chan Chan.
Hands-on with Sixense's MakeVR, a motion-controlled 3D modeling suite bound for Kickstarter (video)
The last time we saw Sixense's Stem motion controller, it was little more than a collection of prototypes. The company showed us a gaggle of Plexiglas boxes containing reference hardware and a 3D-printed shell representing the final product's design. A more functional third unit (a developer kit, actually) allowed us to play with the controller's electromagnetic tracking technology, but the overall experience was fragmented and incomplete. The company finally pulled these disparate elements together, revealing the final Sixense Stem System at CES earlier this month. We caught up with the company earlier this month to take a look at the revised controller, and found a solid, lightweight controller modeled very closely after the 3D-printed mockup we saw last year. In fact, the only major difference we found was the revised button layout: We were originally told the device would utilize a modular faceplate system, but the final version wears a symmetrical button configuration reminiscent of the Razer Hydra. Sixense hadn't met up with us merely to show us the completed Stem System, however -- it was rearing to show us MakeVR, the firm's homegrown virtual reality 3D modeling software.
Build 3D printable castles and pirate ships one cube at a time with Blokify
Alright, this is pretty neat. We suspect the responsible parties won't be mentioning the likes of Lego and Minecraft in its press material, so we'll have to do it in this post. The conceit here is pretty simple: Blokify is an iOS app with a 3D environment where you can build models with cubes -- things like castles, spacecrafts and pirate ships. And once you're done, you can print the models at home or via the cloud through 3D Systems' Cubify service (using the company's ProJet 660PRo). The iPhone/iPad app is free, but additional kits and parts are available as an in-app purchase. Professional printing will be as well, with pricing based on the size of the set you build. You can grab the download in the App Store link below. We played around with it a bit earlier today -- it's fun and dynamic, even if we aren't quite ready to drop the extra cash needed to make our tiny castle a reality.
Newly launched Smithsonian X 3D Collection offers historical models you can print at home
We've already seen first-hand that the Smithsonian has a keen interest in 3D printing and modelling, and it's now turned that interest into something of a public service with a new online collection that's just launched today. Dubbed Smithsonian X 3D, the collection not only includes a browser-based 3D viewer that lets you get up close with the objects it's already scanned -- everything from fossils to historical artifacts like the Wright Flyer -- but also lets users download the necessary files to print an actual model on your own 3D printer at home. That's all coinciding with a two-day conference of the same name that's started today, and is also being webcast on Ustream. You can start exploring the options available at the source link below.
StarCraft II Art Tools Open Beta available
If you're a 3D artist looking for some new toys to get that creative streak going, Blizzard has just the thing for you. The StarCraft II Art Tools package is now in open beta, and includes plugins for 3DS Max, along with a ton of StarCraft II source art files, tutorials, and documentation to get you up and running. The art tools package isn't just a new toy from Blizzard -- it's the same tools that the StarCraft II development team used to create Heart of the Swarm. The tools package allows artistic players to create new models, textures, particle effects, animations, or pretty much any other 3D art asset that you can dream up for the StarCraft II engine. This is, however, a beta -- so there may be bugs with the program. However, Blizzard of course has an official feedback thread for users to leave bug reports and suggestions for improvement. To participate in the open beta, simply visit the announcement page, download the program in either 32-bit or 64-bit version, grab the documentation, and get to creating!
Kinect Fusion tool coming to Kinect for Windows SDK, will help devs create 3D models
Microsoft has kept its internally-developed Kinect Fusion tool all to itself, but now, hot on the heels of Build 2012, the firm has announced that it's working on baking the software into the Kinect for Windows SDK. Concocted by Ballmer and Co.'s Cambridge, UK research lab, the tool can be leveraged to create 3D models of objects or environments, develop augmented reality applications and even take 3D measurements. By the looks of it, creating a model with the tool is a pretty painless process. When passing an object in front of a Kinect or sweeping the hardware throughout an area, the software will use the continuous stream of data collected by the device's sensors and compile it into a 3D model. Intrigued by Kinect Fusion? Hit the jump to catch a video presentation made for SIGGRAPH 2011 by the team behind the software.
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.
Google sells SketchUp to Trimble Navigation for undisclosed sum
While we're probably more accustomed to Google buying assets than selling them 'round here, every now and again the search giant does shed some skin. El Goog's 3D modeling platform, SketchUp, is to be sold to Trimble Navigation for an undisclosed sum reports Reuters. Trimble says it's hoping to use the acquisition to enhance its office-to-field platform. The two firms will also work together to develop SketchUp's online repository of 3D models for designers to use, share and contribute to. SketchUp's blog reassures users that the free version won't change under the move. The deal should get the final nod in Q2 this year.
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.
Paint3D app promises to let you sketch and print 3D models straight from Android
3D printing may still have quite a ways to go before it becomes as ubiquitous as traditional printing, but there's plenty of developers out there working to make that happen. One such example comes out of the House 4 Hack group in Johannesburg, who have been working on an Android app called Paint3D that promises to let folks create 3D models and then print them out straight from their mobile device -- imagine saying that even just five years ago. Unfortunately, that's not available to the general public just yet, but you can get a closer look at the app and the results its able to produce at the source link below, and get an overview from one of the developers in the video after the break.
OrcaM sphere constructs detailed, digital 3D models of wares while you wait (video)
Ever wanted a 3D digital copy of all those Little League trophies? Well, the NEK has whipped up something to lend a hand that's a bit larger than another recent scanner. Enter the OrcaM, an Orbital Camera System capable of producing an accurate, digital 3D model of objects up to 80cm (about 31.5 inches) wide and weighing up to 100kg (around 220lbs). Making use of seven shooters simultaneously, the system photographs the object while projecting various light and shadow combinations in order to determine the ware's geometry. The OrcaM is able to reproduce high-quality digital reproductions with a geometric accuracy less than millimeter (nearly .04 inches). As if that wasn't enough, it produces complete color, texture and reflectivity maps so that every minute detail is accounted for. Once your to-be-copied object has been loaded, the OrcaM takes over and is automatic, churning out the completed rendering shortly after the requisite photos are taken. Hit the video up top for a look at the beast in action.
Kinect sensor wants to guess astronauts' weight, tell them to hit the space gym
How do you weigh yourself when there's no gravity keeping you down? Well, you can calculate your mass by sitting on an oscillating spring and comparing its standing frequency to your riding frequency (NASA's current method), or you could rig up a Kinect sensor to tell you when you're getting fat. Carmelo Velardo, a Eurocom computer scientist in Alphes-Maritimes, France, is developing the latter option. Working with colleagues at the Italian Institute of Technology's Center for Human Space Robotics, Velardo paired the Kinect sensor's 3D modeling digs with a database of weight to body measurements of 28,000 people -- the resulting system can guess your weight with a 97 percent accuracy. NASA scientist John Charles notes that while the rig works well on the ground, it might hit some snags in space. Microgravity can shift water around in an astronaut's body, changing their density and potentially throwing off the Kinect setup's readings. Still, Charles says the technique "appears feasible," and suggests pairing it with the existing weight measurement tools might "provide insights into changes in body density that might be illuminating." Velardo hopes to test the system in parabolic flight soon. If he succeeds, not even outer space will protect us from the shameful judgment of video game peripherals. Now if you'll excuse us, we have some squat-thrusts to get to.
SoftEther's sensor-laden QUMA robot demonstrates poses, intimidates your acting coach (video)
A solution in search of a problem, or a solution to a problem that you were too proud to cop to? SoftEther has just revealed what might be the final blow to Barbie's distinguished career: the sensor-splashed QUMA. So far as we can tell, the human-shaped puppet contains a myriad sensors to pick up precise bends and flexes, and then pipes that information to a screen. Aside from showing your team of ballerinas exactly how their routine should look, we're guessing that the real future here is in far more sophisticated tasks -- things like artificial intelligence, major motion pictures and scientific research. As the saying goes, a video's worth a zillion words, so have a peek for yourself just after the break.
Creepy new Air Force camera can identify and track you from far, far away
Sure you can do neat things like unlock your iPhone using facial recognition, but the Air Force has far grander visions for the tech. Specifically it wants a camera that can identify and track possible insurgents at a significant distance (though it's unclear how far we're talking about here) using only a few seconds of footage. It's turned to Photon-X Inc. to develop a sensor that combines spacial measurements, infrared and visible light to create a "bio-signature" that maps not only static facial features but muscle movements that are unique to each individual. The technology could also be used in targeting systems to identify enemy vehicles and integrated into robots to help them navigate and identify objects... or threatening meatbags. The Air Force even foresees law enforcement, banks, and private security firms using the cams to monitor customers and watch for suspicious activity. Similar tools have been created that use software to analyze video feeds, but they can't match the accuracy or range of this "behaviormetric" system. Normally, this is where we'd make some snide reference to Skynet or Big Brother but, honestly, we're too creeped out for jokes.
Pix4D turns your 2D aerial photographs into 3D maps on the fly (video)
Assuming you own a Sensefly Swinglet CAM or some other high-res camera-equipped UAV, you could be just minutes away from turning your plain old 2D aerial photos into comprehensive 3D maps. Pix4D, a new software program coming out of EPFL -- the same institute that brought us this race of altruistic robots -- takes images shot using an aerial drone to render 3D maps in the cloud in just 30 minutes. Users upload images taken with their flying machines, at which point Pix4D kicks into action, defining high contrast points in the phots and pasting them together based on those points. It then renders a 3D model, overlays the graphics, and spits out a Google Earth-style map. So what's with this 4D business? Well, its developers claim that users can easily see the progression of any model by deploying their Sensefly drone whenever they see fit, throwing the added layer of time into the mix. You can see the fruits of Pix4D's labor in the video after the break.
Kinect + homemade Power Gloves = 3D modeling in free-space (video)
The Kinect hacks keep rollin', and we just keep on lovin' every one of 'em -- despite most being decidedly non-practical. This one actually is, created by Sebastian Pirch at 3rD-EYE, a media production company. He's made a free-space 3D modeling tool using a Kinect camera to track his hands, which he uses to create points in space and draft a model. To provide greater control he then made two Arduino-powered gloves that detect finger touches -- basically DIY Peregrines. Using different connections of finger-presses he can move the entire model, move single points, create new points, create new polygons, and basically do everything he needs to do to create a mesh, which can then be imported into 3ds Max for further refinement. He even manages to make it all look fun, thus besting Lockheed Martin's similar system that's powered by zombies.
UNC researchers develop a system for creating 3D models using images pulled from Flickr, off-the-shelf components
A group of researchers from the University of North Carolina and the Swiss university ETH-Zurich have teamed up to develop a system for creating 3D models of famous landmarks using photos from photo sharing websites like Flickr. Unlike previous projects at Microsoft and the University of Washington, the team at UNC used a home PC (albeit one with four GPUs) to process millions of images pulled from the Internet and construct 3D models of such landmarks as the Colosseum and the Roman baths at Sagalassos (above). And all the models were created in less than a day. According to UNC Chapel Hill's Jan-Michael Frahm, the process improves on current commercial systems by a factor of 1,000 to one. "Our technique would be the equivalent of processing a stack of photos as high as the 828-meter Dubai Towers, using a single PC, versus the next best technique, which is the equivalent of processing a stack of photos 42 meters tall – as high as the ceiling of Notre Dame – using 62 PCs," he said. "This efficiency is essential if one is to fully utilize the billions of user-provided images continuously being uploaded to the Internet." He sees any number of uses for this technology, from AR integration to 3D maps for rescuers in case of a natural disaster.
'Beautiful Modeler' app turns iPad into multitouch 3D sculpting device
Sure, it might not make for as good of an R&B album title as Nilay Patel's "Beautiful Handcuffs," but Interactive Fabrication's "Beautiful Modeler" iPad app is probably a bit more useful (though not as useful with the ladies). The concept is to use the iPad's multitouch screen as an input for multi-finger 3D modeling on a computer, while the tablet's tilt sense lets you navigate around the object. Sure, it's not as slick or precise as, say, the Axsotic 3D mouse, but it also looks a whole lot more "tangible." Unfortunately, the app is currently unavailable on the App Store, and we have no idea if it's ever headed for a computer near you -- Interactive Fabrication is all about the high concept stuff, leaving the execution to individuals -- but there's some freely available GPL-licensed source code if you want to take a crack at compiling and making a real product out of this. Check out a video of the sculpting in action after the break. [Thanks, Danil]
Axsotic 3D mouse takes a spherical stab at an age-old problem
The quixotic quest for the perfect 3D mouse has a long and storied history, but the German-built "Axsotic" 3D-Spheric-Mouse looks like a pretty good attempt. Axsotic tracks a 40mm ball, which can be twisted, pushed, pulled, lifted, and so forth inside its patent pending, sensor-laden cage. Optical tracking watches for rotation in three axis, while magnets track zoom and pan in three axis of their own. The design gives complete camera control in a 3D app to one hand, while your other hand is free to operate a mouse or other pointing device to actually interact with the 3D object in question. Axsotic actually works driver-free on Mac and Windows, and a plugin is available for popular 3D softwares. No word yet on price or availability. Check out some action videos after the break. %Gallery-106991%
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.
