WebHash — Instant Neural Graphics Primitives with a Multiresolution Hash Encoding. Factorized components — TensoRF: Tensorial Radiance Fields. You will need them for scaling to a higher grid resolution. But we believe our simplest dense grid could still be your good starting point if you have other challenging problems to deal with. WebJul 24, 2024 · We reduce this cost with a versatile new input encoding that permits the use of a smaller network without sacrificing quality, thus significantly reducing the number of floating point and memory access operations: a small neural network is augmented by a multiresolution hash table of trainable feature vectors whose values are optimized …
