Nvidia researchers have developed an approach to reconstructing a 3D scene from a handful of 2D images ‘almost instantly’ A new blog post describes the feat, which leverages a popular new technology called neural radiance fields (NeRF), which is accelerated up to 1,000x compared to rival implementations. Nvidia’s processing speed is largely due to its AI acceleration leveraging Tensor Cores which speed up both model training and scene rendering. Other uses foreseen for Instant NeRF tech include providing help for robots and autonomous vehicles to understand the size and shape of real-world objects from incomplete data. It also will surely be of interest to gaming and VR / metaverse developers. Nvidia says the technique can work around occlusions and other uses . . .
