From a Single 2D Photo, 3D Objects Created Easily

A research presentation from SIGGRAPH has been spreading quickly online, demonstrating just how seamlessly we might soon transform two-dimensional photography into three-dimensional objects. Perhaps what makes the “3-Sweep” technique so impressive is that it doesn’t represent some sort of computational breakthrough, or algorithmic trickery. It’s simply good, inventive design. And it allows human and machine to work hand in hand – rather than try to make the algorithm do everything, humans assist by evaluating where the objects are. And making the user interface tools intuitive for those humans also makes the results more accurate. (As I saw noted by researcher …

Transforming Books, Photos in Even More Disney Research

Disney Research is apparently releasing all their latest inventions at once. The most dazzling, atop the air-interaction-feedback project we saw earlier this week, uses captured light field data to transform ordinary photography into the basis of three-dimensional scenes. Say wha?: This paper describes a method for scene reconstruction of complex, detailed environments from 3D light fields. Densely sampled light fields in the order of 10^9 light rays allow us to capture the real world in unparalleled detail, but efficiently processing this amount of data to generate an equally detailed reconstruction represents a significant challenge to existing algorithms. We propose an …

From Disneyland to You: Q+A with Creator of Disney’s Air Interaction Aireal

Ideas for interaction have come from many places. But with illusion and immersion a key part of the magic of digital experiences today, maybe it’s about time to take a stroll to Disneyland. Yesterday, we saw the novel idea of using blasts of air to provide physical feedback without requiring touch: Into Thin Air: Disney’s Aireal Vortex Rings Give Tactile Feedback Where None Exists Today, Rajinder Sodhi of Disney Research, primary inventor of the tech, answers CDM’s questions about what all of this means. CDM: What other research has gone this direction before? Raj: This research comes from a big …

Into Thin Air: Disney’s Aireal Vortex Rings Give Tactile Feedback Where None Exists

The bane of wave-your-hands-in-the-air interaction systems is that you can’t feel anything when you use them. Swatting the air with your hands in front of a Kinect, for instance, gives you nothing in tactile resistance – those invisible objects can be seen, but not felt. So what’s the solution? Well, if the interaction is in the air, you could use actual air for feedback. That’s what researchers from Disney in Pittsburgh, PA propose with their new system Aireal. (Get it? Like the mermaid? Ahem.) The device is a robotic haptic air emitter, bursting short blasts of air called “vortexes.” When …

Scanning the Universe in 3D: The Hottest Kinect Video Yet?

This video, featuring research with Kinect RGB “scans” of three-dimensional space, starts out innocently enough. Microsoft’s depth-sensing camera gets pointed at the world, resulting in some very impressive 3D scans. Then you get about halfway through. For my part, at least, I nearly fell out of my chair. By constructing a 3D model out of the world it sees — even with wildly-shaking camera — the project is able to produce virtual 3D versions of things it sees. Add in textures, just after three minutes into the video, and things get really wild. With lighting, even more so. Then, with …

Evolving Virtual Creatures as 3D Blocks: SIGGRAPH, 1994

As digital media matures, you come to the awareness that real artistry and technique, not just newness, is what matters. So, look back just a few years to SIGGRAPH in 1994 for this extraordinary video by Karl Sims. (That’s not, like, a SIGGRAPH stage name, is it?) The work involves simple physics and 3D geometry, the likes of which will now happily run on your higher-end mobile phone. But there’s some great creativity here, and because of the real-time nature and easier coding of such things, it can become a performance tool. This narrated computer animation shows results from a …

Magical, 3D-Warping Techniques Steadies Your Videos

Technology still has the power to appear like magic. And one place we may desperately need magic: straightening out our horribly shaky, handheld video shots. Software makers like Apple have already offered up some techniques for doing this – in the case of Apple’s Final Cut Studio, optical flow analysis attempts to track the image as it shakes around the screen and compensates by adjusting the orientation of the frame. But a research team at the University of Wisconsin, partnering with Adobe, will present a new approach at the legendary graphics-geeky SIGGRAPH conference in August. They go one step further, …

Cutting-Edge Image Processing Techniques: Watch All the SIGGRAPH 2007 Sessions Free

Until the end of the month, you can watch all the SIGGRAPH sessions for free at siggraph.org. There are many, many sessions worth watching, including Seam Carving for Content-Aware Image Resizing (previously mentioned here by Jaymis and vade). You can’t link directly to a particular session so here are a few titles to search the page for: Advanced Real-Time Rendering in 3D Graphics and Games Practical Motion Capture in Everyday Surroundings Visualizing Quaternions Scene Completion Using Millions of Photographs Line Drawings Via Abstracted Shading (and many similar sessions on toon shading) Interactive Cutaway Illustrations of Complex 3D Models An Interactive …
