NVIDIA's NeRF AI instantly turns 2D photos into 3D objects

A new technology called Neural Radiance Field or NeRF involves training AI algorithms to enable the creation of 3D objects from two-dimensional photos. NeRF has the capability to fill in the blanks, so to speak, by interpolating what the 2D photos didn't capture. It's a neat trick that could lead to advances in various fields, such as video games and autonomous driving. Now, NVIDIA has developed a new NeRF technique -- the fastest one to date, the company claims -- that only needs seconds to train and to generate a 3D scene. It only takes seconds to train the model, called Instant NeRF, using dozens of still photos and the camera angles they were taken from. Like other NeRF techniques, it requires images taken from multiple positions.
