Every weekday at 5:00 a.m., a nondescript gray van rolls down the underground service road beneath the French National Library, in Paris, and arrives at a svelte glass skyscraper soaring above the bustling Seine River. Here, at the Tower of the Times, the van delivers a tiny but astoundingly rich snapshot of life in this country that takes its cultural heritage very seriously.

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.

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.
