If you liked the 100x NeRF speed up from a month ago, you definitely will love this fresh new way to train NeRF 1000x faster proposed in a paper by Thomas Müller and the team at Nvidia that utilizes a custom data structure for input encoding that is implemented as CUDA kernels highly optimized for the modern GPUs. Specifically, the authors propose to learn a multiresolution hashtable that maps the query coordinates to feature vectors. The encoded input feature vectors …
