The underwater acoustic hologram seen in the image projects a sound field towards a water surface. A paper boat is propelled and pushed along the track that is generated by the hologram. 3D-printed ...

Physicists have figured out how to move an object in three dimensions without the need for any physical contact, just by the clever use of magnets. Magnetic Levitation, MagLev for short, is the ...

Researchers at the Institute of Science Tokyo have developed a neural-network-based 3D imaging technique that can precisely measure moving objects—a task long considered extremely challenging for ...

Former CNET editor Dong Ngo has been involved with technology since 2000, starting with testing gadgets and writing code for CNET Labs' benchmarks. He managed CNET's San Francisco Labs, reviews 3D ...

Describing the movement of objects in 3D space requires an understanding of mathematics. ' Moving Objects in 3D Space ' is a website that uses animated slides to explain how to mathematically ...

3D-printed plastic blocks can now be turned into acoustic holograms that generate 3D shapes made of sound, which could function like sonic "tractor beams," according to a new study. This could lead to ...

In recent years various techniques have emerged that make 3D imaging cheaper and faster. Some consumer devices, such as the iPhone X and the Microsoft Kinect, can create such images. And in industry, ...
