Beautifully animated figures seem to be leaping out of the game player I’m holding. Planes and cars are swooping toward me so convincingly that I’m actually flinching. The graphics are detailed; the colors are natural. I’ve never had a better 3-D experience, and here’s the best part: This handheld, multidimensional marvel, a prototype from 3M, doesn’t require me to wear those clunky, chunky 3-D eyeglasses.

New glasses-free 3-D devices are about to hit the market, and their backers are hoping they’ll make 3-D spectacles as obsolete as Smell-O-Vision. These gadgets, described as “autostereo” to distinguish them from the kind requiring eyewear, will include not only game consoles like the one I’ve been playing with but also cameras, cellphones, and tablet computers. Among the first will be autostereo 3-D TVs, just now hitting stores in Japan, and Nintendo’s 3DS handheld games console, due for release worldwide early next year.

New AI Speeds Computer Graphics by Up to 5x

Neural rendering harnesses machine learning to paint pixels

Four examples of Nvidia's Instant NeRF 2D-to-3D machine learning model placed side-by-side.

Nvidia Instant NeRF uses neural rendering to generate 3D visuals from 2D images.

NVIDIA

On 20 September, Nvidia’s Vice President of Applied Deep Learning, Bryan Cantanzaro, went to Twitter with a bold claim: In certain GPU-heavy games, like the classic first-person platformer Portal, seven out of eight pixels on the screen are generated by a new machine-learning algorithm. That’s enough, he said, to accelerate rendering by up to 5x.

This impressive feat is currently limited to a few dozen 3D games, but it’s a hint at the gains neural rendering will soon deliver. The technique will unlock new potential in everyday consumer electronics.

Learn how to measure and reduce common mode electromagnetic interference (EMI) in electric drive installations

Rohde & Schwarz

Nowadays, electric machines are often driven by power electronic converters. Even though the use of converters brings with it a variety of advantages, common mode (CM) signals are a frequent problem in many installations. Common mode voltages induced by the converter drive common mode currents damage the motor bearings over time and significantly reduce the lifetime of the drive.
