Permutohedral Encoding This contains the official implementation of the permutohedral encoding which was originally proposed in PermutoSDF: Fast Multi-View Reconstruction with Implicit Surfaces using Permutohedral Lattices Permutohedral encoding is used to obtain high-dimensional features from low-dimensional space. The features can then be used by a small MLP for decoding density, SDF, RGB or whatever quantity is needed. The encoding works by interpolating features from a multi-resolution permutohedral...
