You can understand that Instant NGP replaces most of the parameters in the original NeRF neural network with a much smaller neural network while additionally training a set of encoding parameters (feature vectors). With this novel intrinsic coordinate, IntrinsicNGP can aggregate inter-frame information for dynamic objects with the help of proxy geometry shapes. It works, but our goal is to render a 3D NERF toy gun or our images. We demonstrate instant training of neural graphics primitives on a single GPU for multiple tasks. Instant NGP introduces a hybrid 3D grid struc-ture with a multi-resolution hash encoding and a lightweight MLP that is more expressive with a memory footprint log-linear to the resolution. するとこの画面が出てくると思います. 2020] uses 2D images and their camera poses to reconstruct a volumetric radiance-and-density field that is visualized using ray marching.

The core improvement of Instant NGP compared to NeRF is the adoption of a "Multi-resolution Hash Encoding" data structure. Instant Neural Graphics Primitives with a Multiresolution Hash Encoding. 5.
